Indesit Wisl 82 error codes
Electronically controlled Indesit washing machines have a self-diagnostic system.This greatly facilitates troubleshooting in case of failures.
Certainly the machine will not tell what spare part should be replaced, but at least it will prompt in what direction to look for malfunction.
All information about faults and malfunctions the washing machine displays in the form of specific codes, for example F-12, F-05, etc.
In washing machines with a display the error code is shown on the display and you need only to read its deciphering.On machines with no display, error codes are also shown, but as a combination of blinking buttons.
Further we will consider in details how to read such codes and give the description, decoding of error codes.

ERROR CODES READING FOR INDESIT WASHING MACHINES.
Here we will tell you what each of the errors of the washing machine means
Let’s try to do it in plain language, without technical terms, so it would be understandable to a simple layman who has nothing to do with the repair of washing machines.
F-01 Short circuit in the motor control theristor.
Fault indicates no motor rotation.Consequently, look at the brushes, motor windings and tacho sensor.Besides everything the reason of occurrence of the given code can be a malfunction in the electronic module itself.
F-02 Blockage of motor rotation or breakage of tachometer winding.The error is similar to the first one, it only indicates that the washing machine does not rotate the drum.Checking the engine, electronic module.
F-03 open circuit in the sensor that controls the temperature of the water or an electric heater relay is faulty.Temperature sensor usually seldom fails, it is easy to check its resistance.Most often the electronic module needs to be repaired or replaced.
F-04 Simultaneous indication that tank is empty and overflowing.Faulty pressostat (sensor that controls the water level in the tank) or electronic module.
F-05 The washer can not drain water.The causes are usually a blockage. filters, water drainage channels and hoses.Besides, the drain pump can be defective, in this case it should be replaced.
F-07 No water heating !Is electric heater, its circuit, electronic module need to be checked.
F-08 The heating element relay is stuck or the level sensor is defective.In practice, as a rule, this error appears due to a defect in the electric heater, it must be replaced.
F-09 The program in the electronic module has malfunctioned.The manufacturer advises to disconnect the machine from the power supply and turn it on after waiting two minutes.The electronic module restarts and the washing starts again.In practice it rarely helps, the electronic module must be repaired.
F-10 The ECU can’t see the tank is empty or full.This code usually indicates a defect in the pressostat.They can be broken and need to be replaced, both mechanical and analog.
F-11 Drain pump winding disturbed, needs to be replaced !
F-12 The indication module (this is the board that shows you what is going on with the machine, washing, wringing and so on, it also has the display and control buttons) and the power module (the board that controls all the processes in the machine) do not see each other.In practice, as a rule, the power unit is defective; in rare cases, the display unit is defective.

F-13 Circuit malfunction; electronic module can not sense the temperature sensor that controls the drying air temperature.Or the drying fan (used for forced air drying) is defective.
F-14 Electric dryer heater not working or consuming electricity.
F-15 Dryer heating element relay is stuck or defective.
F-16 Only for vertical loading machines !The device which locks the drum’s movability doesn’t work.
F-17 Flap lock device defect (only for washing machines with easy door function).
Error codes of Ariston and Indesit washing machines with EVO-II control system
As is known, most modern washing machines have a diagnostic system, which registers failures that occur during operation and displays them in the form of error codes on the control panel. In addition, this system allows you to perform self-test programs, which can check the performance of SM in various modes. Diagnostic system facilitates the search and elimination of possible defects of CM, arising during the operation of these machines.
This system is also available in modern washing machines with electronic control systems of INDESIT COMPANY (formerly called MERLONI).
In all lines of this company’s SMs with the obsolete EVO-I control system, error codes were determined by the number of flashes of the LED indicator (in series). For instance, if the light flashes 5 times at short intervals and the cycle of flashes repeats after a pause, it corresponds to error code F05. Deciphering the error code is no longer difficult, for example, for F05 it is a problem with water drainage (pump, clogging in the drainage path, pressostat).
Usually, when there is an error in these SMs, the handle of the command device starts turning and the execution of the current washing program is stopped. Detailed description of EVO-I electronic modules is given in another article.
In SM made on the basis of control system EVO-II all is a little bit more complicated. As these machines have different functions and design (for example, different panels), some inexpensive automatic machines (without display, for example, AVL series, etc.) have different displays.) many repairers have difficulties with the order of reading error codes. The codes in them are calculated by the combination of light of certain LED indicators. The easiest way to read the error codes is on the models with display (e.g. machines of AVD line, etc.).). They are indicated directly on the display.
It is also possible to read the error codes of INDESIT and ARISTON EVO-I/II CMs with the help of special diagnostic key (SAT), which is connected to the service socket of CM. The key also allows you to test the CM in different modes: both offline and under the control of an external personal computer.
Let’s take a closer look at the process of reading error codes in sms INDESIT, ARISTON of EVO-II series, without using a wrench.
Error codes and how to read them
As mentioned above, in EVO-II CMs with display (AVD line), error codes are displayed on the LCD 1
Fig. 1 Front panel of the EVO-II CM with display (AVD line)
In Fig. Figure 2 shows the front panel of the AVL range SM.
In this case, the error codes are indicated by the TOOL light (LED 4) and the LIGHTING of the SCHEDULE TIMER (KN 1), SUPER WASH (KN 2), SUPER SWASH (KN 3) and RINSE RINSE (KN 4) buttons.
Actually, the “secret” of determining error codes on SM EVO-II control panels with LED indication is quite simple. Each LED is a bit of a binary error code. The very process of error code number calculation consists in matching certain indicators to specific digits of the binary code and to convert this code to decimal notation.
In our case. the KH 4 LED corresponds to the first digit of the binary code, KH 3 to the second digit, KH 2 to the third digit, KH 1 to the fourth digit, and LED 4 to the fifth digit.
If we return to error code F05 as an example, the digit 5 in the binary code will look like: 00101 (5 digits, indicators KN 2 and KN 4 are lit).
And yet, in order not to bore our readers with conversion from one number system to another, here is a universal table (table. 1) to determine the error codes.
Table 1 Error codes of the SM EVO-II (AVD and AVL series)
|Drive motor control triac short circuit|
|Tachogenerator does not give a rotation signal of the driving motor (sensor circuit may be open or short-circuited). Another reason for this error. If the drive motor is blocked|
|Temperature sensor (NTC) circuit is open or short-circuited|
|Level sensor (pressostat) generates signals “empty tank” and “overflow” simultaneously|
|After execution of the draining program, level sensor does not form “Empty tank” signal (drain pump is not working, drain path is clogged or level sensor is defective)|
|Program code not recognized (front panel key error)|
|No heating of heating element (error can occur because heating element is not immersed in water)|
|“Heater relay contact blockage. The heating element or its wiring is defective (leakage on the housing)|
|Error (failure) of the contents of the non-volatile EEPROM|
|No signals from level sensor FULL CELL and empty CELL at the same time|
|Drain pump no voltage (pump power supply open circuit)|
|No communication between display module and electronic controller|
|Drying temperature sensor circuit open or short circuit|
|Dryer heating element does not work (dryer version of this SM only)|
|Dryer heater relay defective (only for SM with dryer)|
|Drum blocked (only in upright loader)|

This is where they wanted to confuse us, but it was not easy. another “cheat sheet” is illustrated in Fig. 4 and Table. 2.
Table 2. SM EVO-II (Low-End line) error codes
Now let’s look in detail at the error codes listed in the table. 1, that is, let’s find out the causes of malfunction and how to fix them (washing machine). Actually all this information is summarized in the table below. 3.
Table 3 Description of SM EVO-II (AVD and AVL line) error codes
|F01||Short circuit (triac) in the supply line of the drive motor Check possible water ingress on the pins of connector J9 Check the terminal block of the drive motor (possible cause of the problem). Check if the contacts of the electronic module are chemically corroded.). Replace electronic module||In 90% of this malfunction is caused by a defect in the drive motor. If motor does not malfunction. See. left column. The EEPROM has nothing to do with the firmware|
|F02||90% of this malfunction is caused by a defective drive motor F02 Drive motor not running, tacho circuit shorted or open Check if the motor is mechanically blocked. Check electronic module connector J9 for tightness. Check the electrical resistance of the tachoductor (about 115. 170 0м). Measure resistance between pins 1 and 2 of J9 connector. If there is a short in this circuit, disconnect connector J9 and check the wires on the tachometer side. If the SM has an asynchronous drive motor, check that pins 6 and 7 of connector J9 are electrically connected to the sensor. Replace motor Replace electronic module||Foam may get on the tachometer, there may also be a loose contact in its socket. If this sensor is shorted. Look for burned out tracks on electronic module and 2-3 burned out resistors. The EEPROM firmware has absolutely nothing to do with it|
|F03||The NTC temperature sensor circuit is shorted or open, or the heating element relay is “stuck” Check the contact reliability of J8 connector. Check the temperature sensor, taking into consideration that its resistance at room temperature (20°C) is 20 kOhms (you can measure it on pins 11 and 12 of connector J8). If the result is different, check the continuity of wiring from the module to the sensor. Replace NTC sensor. Replace electronic module||If the actions in the left column did not lead to the faulty element, re-flash the contents of the non-volatile EEPROM|
|F04||Level sensor simultaneously generates signals Empty tank and overflow The reason for this defect is that the contact group “Empty tank” in the sensor is “stuck”, in this case the SM fills the water up to the overflow level. Drain pump starts automatically when water level reaches this level. Check the quality of the connections of J3 connector on the electronic module. Check the condition of the level sensor (on the pins of the connector and):. contacts 2-4 closed. level “empty tank”;. contacts 2-3 closed. Check level “BATTERY FULL”;. Contacts 2-1 closed. the “overflow” level (no less than half the level of the glass in the charging hatch. Replace level sensor. Replace electronic module||The EEPROM firmware has absolutely nothing to do with it|
|F05||Drain pump is blocked (does not work) or level sensor generates empty tank signal after finishing draining. Check connections at J9 connector. At the moment when the pump is supposed to work, you can check whether there is 220V AC voltage between pins 8,9 of connector J9. Check filter and drain hose. Replace drain pump. Replace electronic module||Most often such a malfunction is caused by foreign objects in the pump. You can check the function of the drain pump by applying an AC voltage of 220V to it. It has nothing to do with EEPROM firmware|
|F06||Not used in AVD and AVL series.|
|F07||After the water filling operation, level sensor does not release the empty tank signal If there is no water in the tank after the water filling operation, the heating element will not be energized. This is a safety function because without water the heating element can burn out. Possible causes:. there is no water in the plumbing or the water pressure is too low;. The water inlet valve is defective;. there is a clog in the water filling path;. The level sensor is defective. After the water has been poured (if there is any), the level sensor contact group Empty tank must be open. Its status is controlled, for example, on pins 2 and 3 of connector J3 of the electronic module. Otherwise replace level sensor and electronic module in series||The EEPROM firmware has absolutely nothing to do with it|
|F08||The heating element relay on the module was constantly turned on (“stuck” contact set) or level sensor generates signals Empty and FULL tank simultaneously Check the level sensor. see. error F04. Check heating element control relay on the module and replace with new one. Check wires connection from L connector to the level sensor. Check the connection of the heating element to the module. pins 5 and 6 of connector ^3). Check if the heating element is working correctly. Replace level sensor. Replace electronic module||The EEPROM firmware has absolutely nothing to do with it|
|F09||Error (failure) of EEPROM content, error SETUP SM In many modules the EEPROM chip is soldered on the module’s board. The best option if the chip is installed on the adapter strip. In this case, the chip is easily removed and installed without soldering, and when installing it on the module, pay attention to the coincidence of the setting keys (on the board and on the chip). If the EEPROM chip is intact, replace the entire module (make sure that the memory chip installed on it has the firmware intended for the particular SM model)||Re-flash the contents of the non-volatile EEPROM. Of course you need a programmer and the corresponding firmware file. Before attempting to flash the EEPROM it is advisable to read its content and save it as a separate file so that the original firmware can always be restored|
|F10||after the beginning of the water filling process (within the allocated time) the level sensor does not generate the signal FULL BAT (on condition that the signal Empty BAT is passive, that is there is already water in the tank). Check level sensor. see. error F04. Check reliability of electrical connections between electronic module connector J3 and level sensor. Replace level sensor. Replace the electronic module||Most often such an error can be caused by a low water pressure when filling the tank (the inlet pipe could be clogged, the inlet valve is not working properly, etc.).). Firmware in EEPROM has nothing to do with it|
|F11||Drain pump no feedback signal (pump power supply line is broken or winding is broken). Check reliability of connection between drain pump and electronic module. Check the drain pump winding resistance on connector J15, pins 1 and 2 (in case the machine is equipped with Easy Door function) or on connector J9, pins 8 and 9. Drain pump winding resistance should be about 170 ohms. Replace drain pump. Replace electronic module||There is absolutely no fault in the firmware of the EEPROM|
|F12||No communication between display module and electronic module. Check reliability of electrical connections between main electronic module connector J11 and display module. Replace the main electronic module. Replace display module||In this case you have very little choice: either the indication module or the basic module is defective. In rare cases, the pad on the side of the display module is shifted. Also check the analogous block on the main module. Based on the experience gained in operating similar ovens, the EEPROM nonvolatile memory has not caused this type of defect|
|F13||Drying temperature sensor circuit open or short-circuited (drying oscillators only), Proceed in the same way as in case of the error F0Ç with the only difference that the drying temperature sensor circuit is different|
|F14||Dryer heating element does not work (dryer only for SMD). Check the power supply circuit of the dryer heating element, as well as the heating element itself|
|F15||Drying resistance relay does not work (only for VM with drying). Check the power supply to the heating element and the heating element itself|
|F16||Drum is blocked (only in upright loader). Check the drum lock (power supply to the locking solenoid)|
|F17||Door hatch lock is not working (or door is open (for SM with Easy Door function). Check 220V voltage on pins 3 and 4 of connector J4 (not in the STANDBY mode) and also between pins 3 and 5 of the door locking switch. Check operation of the lock feedback microswitch (with the door closed and the car off) on pins 1 and 2 of connector J4 of the electronic module. Check that wires from connector M to the door locking switch are securely connected. Check that the door lock is securely latched. Replace the door lock. Replace electronic module. If the SM does not have the Easy Door function, carry out the same operations (see Energy Saving Module, page 14). Check only if there is 220V voltage on pins 2, 3 of connector J4 and on pins 1, 3 of the door locking switch. The microswitch is not checked in this case. Make sure the door lock does not catch because it is missing||The EEPROM firmware has absolutely nothing to do with it|
|F18||Error in communication between controller chips and DSP (asynchronous motor control processor) on the main electronic module. Replace the main electronic module||Such mistake is extremely rare, in any case, it has never occurred to the author|
EVO-II modules and their peripherals
As you know, the EVO-II washing machines have many modifications. They differ not only in functionality and appearance (only their control panels have several variants), but also in their electronic “stuffing. Let’s look at the main varieties of EVO-II modules. We must note right away that the appearance of the display modules (with LCD and LED indicators) is not shown on the drawings. In fact, it makes no sense, because the indication modules are quite simple and have only two connectors: one is designed for communication with the main module, and the second is connected to the program selector.

Indesit washing machines error codes (Indesit)
Before listing the error codes, it is worth detailing the different ways of displaying the errors used in the different Indesit models: they can vary greatly depending on the range.
The earliest models
The first models with the EVO-I control unit in which an error display appeared (the W, WS, WDS series, etc).д.), had very modest means of display and control: only the selector knob and a couple of indicators. The error is displayed in the following way: the selector would turn continuously and the power indicator would light up at 5-second intervals (for about two seconds): it could blink with different frequencies or be lit steadily. Now, the error number. is the number of such 2-second flashes.
Error display by indicators
The later EVO-II models have a much richer control panel, with many indicators (LEDs), although they still lack a display: here, with certain blinking indicators, the error code is displayed. The principle used was as follows: five indicators were assigned a conditional number to the power of two. 1, 2, 4, 8, 16. and the error code (more exactly, the number) was defined as a sum of numbers of lit or blinking LEDs; for example, when the LEDs 1, 2 and 4 are lit, the error is 11 (128). It should be taken into account that the dashboard looks somewhat different in different models, respectively, and the arrangement of the indicators for displaying the error will be different. The following are the most common variants.
With Low-End control unit (WIU, WIUN models, etc.).д.)
For your convenience, here is the table of correspondence of indicators and error codes: it does not contain the specific names of indicators (they depend on the SM model), but the numerical equivalents of LEDs. The names can be seen in the pictures above.
