24/7 Dishwasher water doesn't drain in San Jose, CA

Issue description:

Even reliable household appliances sometimes cease to please with flawless performance. Similar problems include the following: the dishwasher does not drain the water, the dishwashing process is interrupted. Nothing seemed to bode well. In fact, the main reason for such a breakdown is improper care.

The dishwasher does not drain the water: reasons When dirty liquid is "in a traffic jam", unable to go into the sewer system, the main reasons may be: Clogged filter elements - the most common malfunction. This happens when users neglect to clean the dishes from food waste before loading them into the dishwasher or do not clean the filter itself in time.

Kink in the drain hose, which is the result of an unsuccessful installation or rearrangement of kitchen furniture.

Clogged drain hose or pump, which occurs when debris somehow gets through the filter into other parts of the drain system.

Damage to the pump or control unit can also lead to similar consequences.

Failure of the water level sensor ( further also pressostat). It is not part of the drainage system, but it may incorrectly inform the software module (hereinafter also referred to as the control unit, ECU) about the water level in the chamber.

Removing blockages

In each of the above cases, in order to restore the functionality of the equipment, it is necessary to perform certain manipulations.

Cleaning the filter and checking the pump In the dishwasher, the filter consists of two elements connected together. This structure is located in the bottom of the working chamber. In most models, the main filter is framed by a filter mesh, which is also a filter that does not allow food waste to pass through.

The inner "glass" is made of coarse mesh and is a coarse filter element. When water passes through this part, it falls on the surface of the outer metal mesh with fine cells - a fine filter element, which finally cleans the liquid from food debris.

To clean the filters, follow these steps: Remove the dish baskets from the PMM. Unscrew the filter cap located at the bottom of the chamber, next to the spray gun. Remove the two dirty filter cups from the niche. Rinse both filters thoroughly under running water. If necessary, use a toothbrush and any kind of dish detergent. Open the cover that is located under the filters and gives access to the pump impeller. Carefully check that the impeller turns freely. If something slows down it, you should remove the blockage with tweezers. After cleaning, return all the parts to their places.

Cleaning the sewage system In this case, the pump does not have time to remove all the water during its operation, because the sewer system is clogged. It is easy to localize the malfunction - disconnect the drain hose from the drain. If a dirty liquid has flowed out of it, try to clean the part on your own, for which: Pour boiling water with a diluted pipe cleaner into the drain hole (perhaps only the siphon is clogged). If there is no result, try cleaning the pipe with a steel cable (if you have one) or invite a plumber.

Checking the drain hose It so happens that cleaning the filters and checking the sewer does not lead to the desired result - the water is still not pumped out. This could mean that the drain hose is clogged or kinked. First, check if the hose is pinched by furniture or other objects. Feel it along its entire length (this manipulation helps to remove the blockage). After making sure the hose is clean and not pinched, turn on the dishwasher to check the drain system. You can disconnect the drain pipe from the sewer and direct it into a large container to make sure it works.

Checking and replacing the pump If the Bosch dishwasher does not drain the water and the sound of the pump is not heard, you will have to check and possibly replace this part. To do this: Remove water from the chamber in any convenient way. Remove the drain filter. Lay the clipper on its side. Remove the pallet and disconnect the Aquastop sensor from it. Remove the pump and disconnect the pipes from it. Check the impeller (it should rotate freely). If it sticks, replace the pump. Check the resistance at the pump contacts with a multimeter. It should be within 200 ohms if the pump is working properly. Otherwise, the pump must be replaced. Make sure the pump is supplied with voltage from the control box. If not, the ECU may be defective.
