By loading the dishes and turning on the “Start” button, do you hear that the dishwasher is buzzing but not filling with water? Or, did the car start the wash cycle, but at the discharge stage it stopped and refused to discharge the waste water? The most common causes are blockages in the system.
Types of blockages and their causes
If the dishwasher does not drain or flood water, the reason may be a clog. Depending on the brand of the dishwasher – “Bosch” (Bosch), “Siemens”, “Ariston”, “Indesit”, Eyelid — an error code may appear on the display. The code indicates a problem that needs to be found and fixed. If there is no error on the scoreboard, you will have to find the cause of the problem on your own. First you need to determine the type of blockage: external or internal.
- The sewer system, pipes or junction of a drain hose with the sewage were hammered.
- Siphon clogged (when connected through it).
- Bent over, twisted drain hose. This happens when the connection is incorrect. The hose may have been transferred by a foreign object.
What to do in this case? Check that the drainage system is properly connected. Shut off the water supply, disconnect and install the hose correctly. Also, unplug the end of it from the sewer and clean the blockage with special means. Be sure to check and clean the siphon.
An internal blockage appears if you have cleaned the dishes poorly before loading them into the chamber. Pieces of food, pieces of napkins, and toothpicks flow into the pan with water. If the dishes are broken when washing, then fragments also penetrate the filter and drain.
What parts can be clogged with garbage:
- Drain filter. It serves as a barrier behind which the impeller of the pump and the pump itself hide. Water passes through the filter to allow water to go to the drain or to start circulating through the chamber again. Therefore, it is recommended to clean it twice a month, and even better to check the filter after each wash.
- Spray bottle. Water is pumped by the circulation pump to the sprinkler, from where it flies out of the nozzles (orifices) under pressure. Nozzles are clogged — water does not flow, the system gives an error or stops working.
- Clogged drain. If the filter fails, food debris penetrates further into the pump, the drain hose.
- Inlet filter. At the entrance to the filler valve is a fine mesh, which stops large particles of debris from the plumbing. Over time, the part becomes clogged and needs cleaning.
How to clean parts and eliminate clogs
To solve problems with sewage one can call a repairman or cope on their own.
- clean the contaminated area with a thin wire brush;
- Disconnect the siphon and rinse it with water;
- Add special powder and use a plunger.
You also need to clean the drain hose: under pressure from a tap or mechanically (using a brush). Internal problems will have to be given more time.
