Whirlpool AWM 045-1000 washing machine has suddenly stopped working and warning light "WATER STOP" has come on. Any ideas for a fix?

Question edited for clarity, add maker, toss in some CAPS.
Question moved to maker category.

Likely needs a new controller board.

No cold water will stop it b4 rinse change water valve or turn cold water on all the way

The door lock needs to be replaced. I would recommend using a technician to replace the part just to be on he safe side.

check inlet valve

Hard to know without more information, have you checked pump filter in flap at bottom of machine or tilt forward if you get a little bit of water you have a leak inside and a sensor will stop machine, if it will run after tilting machine that would confirm your problem.

Hi,
May be the belt at the back of the machine is loosen or cut off kindly check it and replace the belt

hi.replace door seal

Hi.
I assume you have checked to see if the pump is working,
Select drain and spin, if water does not go away, then you have a pump problem, which will stop the programme completing.
Please leave feedback.
Thanks

Try checking for good water supply.
Pull out detergent tray and check for good water supply during filling.
if poor filling-
Try checking the hoses.
Turn taps off, disconnect from machine, place hose end in sink, turn tap on and check for good water flow.
if the hose has a red indicator in the side of the hose (end which is fitted to the tap) - Red indicator is a failed hose.(for models with Water Stop hose type "B")

the despencer has a motor on it are a water valve that puts the water into the right despencer at the right time to make it work look under the top if its a water valve type needs new valve
