Re: hot water valve not closing
There's a water level sensor which sends the electronic signal to the control board to close the valve. There's tiny little pipe going from the top of the drum. at the end of it, the level sensor. Also make sure you've used Normaly Closed type valve (NC). None of above? then it's the control board

Yes you could, but the machine is not built for it.
The other problem I see time to time is that the water valve gets stuck due to the heat. Its a cold water valve, not desiged for hot water. (internal gaskets and o-rings dont like heat).
And, your tap hotwater is about 65-80 degrees celsius. Do you want that for all your clothing? I dont think so
make sure the valve is rated for the pressure of your water. I was called out to one that was unable to open or close against the pressure on the water supply. changed it for higher rated valve and it was then ok. look for the bar or psi pressure differential rating.
HI .THIS SOUNDS LIKE THE SOLENOID VALVE STICKING.INTERMITENTLY.WATER INTHE PIPE DOESNT NORMALLY FREEZE UP.IF IT DID THEN PROBABLY THE VALVE WAS LEAKING IN VERY SLOWLY THUS FREEZING UP EVENTUALLY.WATER VALVE IS CONNECTED VIA THE TIMER AS IT'S ROTATING.HOPE THIS HELPS ALI
Maybe I am not understanding your problem exactly, but if you have the instant hotwater system installed it should be measuring the temperature of the water in the hot water line and if it drops below the set level it should open the hot water side until the temperature is reached. If it was installed correctly it puts the hot water back into the cold water line so it isn't wasted.
Be sure cold supply line is going in bottom fitting and hot line attached to top fitting. Any by-pass or vlaves attached to lines in between should be closed. A check valve at top (hot) between tank fitting and hot line is usually recommended as well.
It sounds like one of the automatic water fill valves in the machine is leaking water when washer is off and the valves are closed. There are two manual water supply valves at the wall behind the washer, one for hot water and one for cold. Close the manual hot water supply valve and allow the washer to sit and see if it fills with water. If it does fill, then the cold water automatic fill valve is leaking. If not, then open the hot water manual supply valve and close the cold water manual supply valve. Allow the washer to sit again and see if it fills. If it does then the hot water automatic fill valve is leaking. Replace the leaking valve in your washer. You can order the new valve online using washer brand and model number on a appliance parts web store, or maybe even find it at a local appliance parts store.
Check that the by-pass valve(s) on or near back of water heater are in the proper position. If your stumped on how they should be for normal operation, remember this. Cold water has to flow into bottom of tank, so that valve needs to be open straight into that fitting. Then the hot comes out the top, so that valve has to be open as well. Any valves in between those lines need to be closed, otherwise it will mix cold and hot . If still not sure, get back to me, with location of any valves there, and I'll guide you through it.
1. Close hot water valve behind washer.
2. Remove hot water line from washer side and place it in the drain.
3. Open hot water valve to ensure pressure and hotwater is ok in your drain.
4. If not, problem is home related.
5. If pressure and hotwater are ok, then see if your fill valve filter is clogged where you disconnected the hotwater hose attached to the machine.. Its called a fill valve. Sometimes they get clogged.
6. If the hot water side of fill valve looks ok with no blockage, then you might be looking at a new fill valve.
It sounds like a little piece of trash (precipitated solids in the water line) have gotten in the water valve, or, the fill switch has failed.
If you know how to use a voltmeter, then see if there is voltage always applied to the water solenoid. If not, the water solenoid valve is bad. If it does have voltage all the time (when it's not supposed to be filling) then it's the fill switch.
What brand and model do you have, most domestic units have a combination hot/cold valve? You just need a meter too verify the valve is closing, if the valve solenoid is closing you may be having a water pressure issue, too much water pressure can cause leaks.
