n,
The valves move when 24 VAC is sent from the EasyTouch to the valve. If sent on one wire, it will move the valve all the way one way, and when sent on the other wire, the valve will move 180 degrees the other way.
If the valve quit working, either the valve or wiring is bad, or the EasyTouch is not sending the voltage to the valve.
The first thing to do is move the little toggle switch on the valve from one side to the other.. The switch has an on/off/on switch.. In operation the switch should always be in one of the two on positions. Moving the switch from one on to the other on will cause the valve to move 180 degrees..
If both the Intake and Return valves stopped, it is unlikely to be the valve itself as I don't see both valves going bad at the same time.
I suggest you put the system back into the pool mode and watch what happens to both valves.. The put it in the Spa mode and watch what the valves do...
Please let us know what the each valve does when in the pool mode and then the Spa mode... You can also try moving the toggle switch on each valve and tell us what happens in each case.
Do you have a voltmeter???
Thanks,
