Insufficient water in the dishwasher can cause poor cleaning. If the floats get stuck in the raised position or the pressure bowls or pipes get blocked with slime, the dishwasher won’t fill with water. Another likely cause is a clogged inlet screen or faulty inlet valve as on this Zanussi dishwasher.

1 check to see if you have water to the dishwasher inlet valve, also check for kinked pipes or a faulty tap,

2 All the pipes that go to the main pressure switch assembly will need to be checked for blockages. By blowing into the pipes you should here the pressure switch click, this tells you that the switch should be working correctly if fitted.

3 Once you have cleaned everything and replaced them try the dishwasher again if it works great you have not need to buy a new valve.

4 If the dishwasher still does not fill you will have to try replacing the main water valve, see products below. You will need your model number to find the right one for your dishwasher.
