When the dishwasher does not bring water


If the dishwasher does not collect water, the customer service does not have to be called immediately. In a thorough exclusion of a number of possible causes, the error is often itself. The device must be tested internally as well as all supply lines, components and connections.

Check step by step

As the first cause and visual test, you should examine whether something has changed in the overall behavior of the dishwasher. Common cause, if the dishwasher does not bring water, is the imperfect pumping. In this case, the dishwashers automatically block the supply of new water.

Floats or pressure sensors serve as dosing units for the right amount of water required. For most dishwashers, a combined solenoid and air valve will do the job. It also shuts off automatically in case of malfunction. If other causes have been excluded, the component can be checked by experienced DIYers themselves.

Conventional cause of interrupting or adjusting the water supply is often pollution. If any part of the dishwasher clogs, this often leads to a failure of the water harvesting function. Grease deposits clog nozzles or stick the pump sump to the bottom of the dishwasher.

So look for the cause

  • Boiling water
  • Chemical lime and mildew cleaner
  • needles
  • nails
  • Two individual magnets
  • Wrench
  • Eventual resistance tester

1. Check power connections

After disconnecting the dishwasher from the power supply, access all electrical connections. Check the solder joints or cable lugs on the pump, the solenoid valve and all other cable connections.

2. Check water connections

Follow the course of all water pipes and look for porous or polluted areas. Test the fit of the hose connections. Release the pump sump on the bottom of the dishwasher and check for dirt.

3. Clean lines, nozzles and valves

Remove all soiling with chemical cleaning agent suitable for dishwashers. Disassemble, where possible, contaminated pipes and fittings and place them in a cleaning bath. Non-removable components can be cleaned with an inserted needle or nail and two hand magnets.

4. Check solenoid valve

If you have experience with an electrical resistance meter, you can measure the removed solenoid valve to proper function.

5. Check aquastopp

Often in conjunction with the solenoid valve unit works the aquastop. Remove it and if you can not test it yourself, have it done by a specialist.

Tips & Tricks

Only disassemble components from your dishwasher if you are sure of what you are doing and how the re-assembly must be carried out professionally. In the event of a faulty procedure, a lot can happen from the final uselessness of the dishwasher to the risk of fire.
