How to descale a dishwasher?

Dishwasher is subject to scale formation, which affects its performance and life time, that’s why in this article we will try to understand what is the best means to scale the dishwasher and how to remove limescale in domestic conditions.


This part should be cleaned once a week if you use the dishwasher daily. The filter accumulates a lot of grease, which clogs the cells and causes an unpleasant smell.

After removing the filter, rinse it with clear water or soak it in a soap solution for 10-20 minutes. Then rinse it with clear liquids and reinsert it.

Mechanical cleaning of components, parts, and surfaces

The more often you use your dishwasher, the more often you need to clean it. For example, if you use the washer-dryer daily, experts recommend cleaning it once every 12-15 days. In addition to food remains, the machine can also accumulate scale, since the hardness of water in the plumbing is often quite high. These factors must be taken into account to ensure that your kitchen helper has a long and trouble-free life.

Dishwasher gets an unpleasant smell if left unchecked

Dishwasher grease and limescale can be removed using both well-known folk remedies and chemicals specifically designed for the dishwasher.

Removing the dirt from the filters

Every dishwasher has a combined coarse and fine filter. It is located in the bottom of the chamber, next to the spray fan (hereinafter also referred to as the sprayer). Filter elements need regular cleaning to remove dirt and food debris. If the washer-dryer is used daily, the filter itself should be cleaned after every 5-6 wash cycles, or even more often.

You need to remove the dirt from the filter and the grid around it

Cleaning the filter element is simple:

  • Turn off the dishwasher.
  • Remove the lower basket from the chamber and remove any residual liquid on the bottom with a sponge. If there is dirt on the framing grid, remove it (see “Cleaning the grid”). photo).
  • Locate the filter near the atomizer and turn it counterclockwise 90°. On some models you just need to pull the filter cup upwards.
  • Check the opening under the strainer for dirt and solid food remains. If there are any, remove them with a sponge.
  • Check that the pump impeller rotates smoothly. To do this unscrew the screw, remove the cover that covers it. Do not allow small objects to get under the impeller and jam it.
  • Rinse all the filter components in warm water together with a detergent that dissolves grease. Use vinegar or citric acid if heavily soiled. It is necessary that the cells of the fine mesh were free of dirt and grease.

In addition to the drain filters, it is necessary to regularly check the sieves of the inlet filters, located at the inlet to the body of the washing machine and at the inlet to the inlet hose on the side of the water supply. These parts prevent rust from the pipes and other dirt from entering the machine.

Cleaning spray nozzles

No matter how well the filter reduces the degree of water contamination, small particles can still pass through the fine mesh screen. If you add lime scale to these, the combined contaminants can clog the holes in the atomizing nozzles. So their visual inspection and periodic cleaning is also necessary.

Spray nozzles that need to be checked and cleaned from time to time

The cleanliness of the holes in the beadles determines the quality of the dishwashing. Therefore, periodically perform the following procedure:

  • Remove the upper basket to which the sprinkler is attached from the chamber.
  • Remove the atomizer head by pulling the latches.
  • Remove the lower basket and remove the lower spray arm.
  • Remove grease buildup by washing the blades with water and detergent. Check the holes by spraying the nozzles with a stream of water. Clean blocked holes with a toothpick or similar tool.
  • Reinstall in reverse order.

Removing the upper spray arm

If you have trouble removing the spray arms, refer to the user manual for your dishwasher.

Removing Dirt from Baskets

Fouling grease and limescale deposits are not easy to clean from the surface of the baskets. To make the job easier, use one of the commercially available dishwasher cleaners (see below).

  • Place the baskets in a large container so that they can be completely emptied.
  • Fill them with boiling water and add the detergent.
  • Leave to soak until the water cools.
  • Now use a soft brush to remove any softened residual dirt.
