How to Clean a Dishwasher

In order for a dishwasher to perform its duties properly, it is necessary not only to observe the rules of operation, but also to take regular care of the equipment. Otherwise, you may encounter troubles such as the smell of must, fatty deposits and mould. And in particularly neglected cases – with the breakdown of the equipment itself. All about how to clean the dishwasher at home and extend its life, you will learn from our proposed article. We’ve described in detail the ways, steps, and recommended products, like dishwasher cleaner, to take care of your dishwasher and listed some tried and tested products. With our advice, you will eliminate any problems with your machine.

Mechanical cleaning steps

Although many modern dishwashers have a self-cleaning function, this does not save you from periodically washing the filters and other machine elements. And even professional care products may not be enough when it comes to clogging or operating in hard water. Therefore, the key to a perfect dishwasher is comprehensive and timely care. Flushing the drain and fill filter On the drain of any dishwasher there is a multilayer filter, whose task – to prevent clogging the flow with pieces of food and other garbage. But even if you diligently follow the manufacturer’s recommendations and wipe the dishes with wipes before each load to remove food scraps, fat or hard water can cause the appliance to stop without completing the full wash cycle.

To get to the filter, proceed as follows:

  • Disconnect the dishwasher.
  • Remove the bottom basket, collect the remaining water at the bottom of the appliance with a sponge.
  • In the lower part of the case next to the sprayer we find a round hollow – in it there is a filter, which consists of a metal membrane for fine cleaning, a plastic glass with large holes and an inner mesh.
  • In the new dishwashers, this element can be easily removed by simply pulling it up or unscrewing it counterclockwise. But in models older than 7-10 years you may need a screwdriver, pliers and other handy tools from your home master’s arsenal.
  • Remove water with a sponge from the filter opening itself and inspect the niche for contaminants – if any solid waste particles get through the filter protection, they could damage or break the pump.
  • To make sure that the pump impeller is working properly, you can unscrew the self-tapping screwdriver, remove the protective strip and carefully turn the blades. If they rotate easily and no foreign objects are found, they can be reassembled. Otherwise, you will have to disassemble the pump structure.
  • All parts are then cleaned of debris and washed with warm water and any grease solvent. If the filter has not been cleaned for a long time, the mesh cells are clogged or the glass is covered with limescale, you can soak these elements for a couple of hours in a solution of vinegar, citric acid or spray the dishwasher.
Although the exit filter is the most popular place for clogging, a comprehensive mechanical cleaning of the dishwasher does not prevent you from checking the condition of the fence hose. Sand, rust and salt particles may accumulate here. To clean the fill in the dishwasher, disconnect the filler hose (and at the same time rinse it). There must be two filters inside: one immediately behind the T-crane and one at the inlet of the appliance itself. Both grids are removed and rinsed with warm water. If they are damaged or severely clogged, they can be replaced with new ones – such flowers are inexpensive. After checking, all filters are collected in the reverse order.

Checking and cleaning the sprinklers

Another problem element that can disable a dishwasher is the spraying system. Although the water from the hose is supplied already cleaned of coarse impurities, fine particles of sand and calcium salt can easily pass through the inlet filter cells. In addition, water with high stiffness can disable the sealing gum on the rotating rocker arms, so it is advisable to inspect them at least once a month.

The principle of cleaning the sprayers:

  • Take out the upper basket together with the rocker arm attached to it.
  • Bend out the latches and remove the sprinkler blades.
  • Take out the bottom basket and remove the bottom bracket – normally, just turn the bracket counterclockwise and pull it up while holding the part in the middle.
  • Inspect the condition of the seals (replace if necessary).
  • Flush the blades under running water, clean the nozzles and connectors.
  • Reassemble the system and make sure that the sprinklers rotate without interference or force.
The rocker arm fasteners may vary from model to model, so check the instructions before the first cleaning to make sure you do not accidentally break the latches.
