Diplomat dishwashe will not fill

ur inside filter is full of stuff or blocking the return line

Assuming the water tap is open and the water pressure is correct, it is likely the inlet water valve in the dishwasher is faulty. If you hear a click at the time the cycle starts but still there is no water then the inlet valve needs to be replaced. Also check the inlet hose for any kinks or blockage of the filter attached to the tap inlet.
The inlet valve looks like this item


Diplomat ADP8342 Solenoid Valve

It is likely the door switch is faulty and not letting the dishwasher start the cycle. Need to have the full model number and make of dishwasher to advise further.

theres a hose that goes from the dishwasher to the sink see if the hose is full of junk

----------This will help.Thanks.

The most common cause for no washing is a failed wash pump motor. Which is probably the single most expensive part to have replaced on a dishwasher.

Please can you give me the dimentions of this Dishwasher Diplomat Model ADP 8132, as I have got to get a replacement and have been told that the Hotpoint FDL570X is the replacement offered,Many Thanks,

check to see if you have anything plugged

i had same problem and have found that under the lower basket the connecting bar to the spray arm had become detached this can be reattached by inserting the two nozzles back into position and pushing down youll see what i mean ! however i have found i now have to do this after every wash ,am currently onto diplomat to rectify this completely , hope this is any use.
