No bathroom heat


Recommended Posts

You are right about the stuck valve being a first suspect. Not an unusual problem. Feel if the corresponding outlet feels cool compared to others and smack it with a screwdriver handle or some other not-too-violent way. Hopefully that works and you won't even have to open the box to troubleshoot further. This pic might help, your check valve should be accessible above the box cover.

The service manual explains troubleshooting the pumps very well.  If you tap the valve and it don't work, take cover off and check wiring on  both sides of the second relay (three are stacked).  I found wiring loose and that fixed it.

Good luck
