Washer will not fill, hot or cold. I filled it manually with the hose and it runs through first part of cycle, after first spin and drain it won't contiinue after I've manually filled it again- I have to reset the main dial to the beginning of the wash cycle. Anyway, today I removed the washer sheet metal cover and exposed the internals. I tested the voltage going into the solenoids of the water inlet valve and showed 120v. So I thought the valve had gone bad, but also felt it was strange that both solenoids would quit at once. So I rigged up the valve with water supply and some alligator clips to power the solenoids from the wall outlet; when power was turned on, the solenoid opened and water flowed through the valve. Repeated with the second solenoid and had the same results. Now I don't know what to do. What else could be keeping the water valve from flowing when it's in the machine?

Good diagnostic technique!

The strange thing here is that when the timer sends 120v to the solenoids they don't open, but when you by-pass the timer and send current directly to the solenoids they do open. This situation should not exist, if current opens the valve assembly in one instance it should open it in the other.

Try different cycles and different water temp selections. If you still don't get water I can only suggest changing out the timer, and if you buy from this site and the new timer does not fix things you can return it.

Thanks for your reply sidfink43, after reading your thoughts about it, I decided "yeah, there's power coming from the wires that supply the solenoids and the solenoids worked as designed when I powered them up outside of the machine- it makes no sense."
So I reinstalled the valve back in-line, connected the water supplies and pulled the dial switch to start a cycle.....and WATER!!!!
I don't know what happened, but it's working. I've reassembled the machine and am at the moment running a small load to see if the machine runs through a full wash. So far, so good!
The only thing I can think of now is that the tankless water heater we have in this house (only been living here about 10 months) may have caused some sort of freezing of the solenoids because I've notice large quantities of scale build up in the hot supply side of the machine's inlet which I've had to clean the screens almost weekly for the past few months or the hit side would just dribble in due to the mineral buildup in the inlet valve screen(?).

Great, and I think you are correct in that scale on the screens may be one of the causes of your problem. It may also be that the valve assembly was a little stuck because of scale and your hooking power directly to them was enough to unstick them.

Thanks for the update, what you had was a real mystery.
