I have a fisher and paykel top loader model MW512au. The washing machine is not letting any hot or cold water in..before it was just letting in hot water and I had to put in the cold water by hand. But now it is not even letting hot water in. It is completing all the cycles except when there's no water in the machine and then it stops. Does anyone know what the problem could be?

it could be that the water level got to high and came out of the valve you could try putting a cap on the valve and see if that works and if it does not then it might be a bigger issue.

Water will run out the hot valve if no hose on it or cap bung.

Hi just read your posting.Have you selected cold only?Are the hoses from the taps going to the correct water valve?Cold tap to c on the machine and hot tap to h on the machine.What is the model number of the machine?The model number sticker is on the back of the machine up top.Please reply with additional information and I am sure I can help rectify the fault.Looking forward to your reply/

The inlet valve has failed & needs to be replaced unless you don't use hot water then you could just swap the hoses over.

You will need to replace the "cold water valve" with this part.

If it is a musical rippling sound & hot & cold lights are flashing that usually indicates it is not getting water quickly enough. You can open the lid while it is filling & look. If water is just trickling in and taps are fully open then replace the inlet valve with a new one.

pretty sure you will have to replace the hot water solenoid valve :)

You are better off swapping the valves over in the machine until you can buy a replacement valve. I've done this for a month or so until I replaced the valve. Works as long as you only use a cold wash and your cold water is not too cold as to make the machine want to add some hot. If it does this then simply press start to clear the fault.

turn off water
disconnect fill hose from tap
examine screen inside hose end for 'muck' blockage
clean screen
reconnect hose
test washer
if no fill
replace water solenoid valve

note: cold water valve fails first, it gets most use,
if only using cold water, you can simply swap the hot and cold hoses at the tap, and swap the hot and cold electrical connectors on the solenoid valves, the hot solenoid is no the cold one and the washer can be used, cold only, for about as long as it has operated thus far..

If you talk with the company, they'll explain that their machines are designed to clean clothes in cold and warm water and that, in most instances, they don't feel "hot" water is at all necessary; especially if you use the soak cycle. You have to remember that the company is all about eco solutions and energy efficiency. They included the 'no hot water setting' work around just to as a customer accommodation. I haven't found that it takes all that much pressure, you just need to keep them depressed long enough for the unit to get the message and signal that it has.
