Hi, welcome to Just answer


Please tell me its complete model number


and how old is it ?

JACUSTOMER-650cdm1e- : its a hotpoint ultima 9kg wmud 942
JACUSTOMER-650cdm1e- : 3 years old

OK and the pump is now completely cleaned ?

JACUSTOMER-650cdm1e- : Yes and it wasn't very dirty.

ok F05 error indicates pressure switch is stuck

JACUSTOMER-650cdm1e- : Is that at the water inlet?

no, if you have already cleaned the pump then you will have to check the small pipe attached to pressure switch

This is the pressure switch

JACUSTOMER-650cdm1e- : Ok, I had the top of the machine earlier and saw this. As for the pump, I only open up the outlet at the bottom front of machine, will I need to locate pump as well?

No just try to clean the pressure switch and a small hose attached to it


with the back of screwdriver just give tap this switch few times as well lightly


take that tube off and blow through it to make sure it is clean


then check if it works, if the error is still there check the drain hose connecting the unit and also remove the pump to clean it completely


let me know how it goes

Stevie, if everything is working fine and still it wont fill with water...and also if you have cleaned the inlet hose and checked the valve then the problem is with the water inlet valve not the pressure switch... please let me know if you need more help..Thanks.
