Ok Guys, had an interesting moment today.. switched on the water pump, nothing happened....but the fill and water pump lights both came on.. either switch would cause both lights to come on..from all locations..........but nothing, no water flow unless connected, no water pump noise...kept cycling everthing, looking for a response...eventually got the water pump to kick on, and started hearing a sound, that i presume is the valve when you operate the fill switch........I still see a faint glow , when I turn the water pump switch on ..from the fill switch, but basically, back to normal..any ideas?.....dave and wendy
Bad connection, bad ground, or intermittent loose connection. could be the switch its self.
If you still have the electric fill valve, I believe there's a relay controlling it that's known to act up.
I recently had a similiar problem. The water pump and fill valve relays are located behind the white fiberglas panel located on driver's side of main bay. Found a loose wire on the relays.
Good Luck, Dave Abel
Any knowledge out there on this....Fill valve relay on order, do not know if it is bad, but intermittent problems now with water pump that seem fill valve related...sometimes, both lights come on with either switch...when this happens, water pump does not work....sometimes i hear no sound below the floor when operating the fill valve. sometimes i do.....when it seems to operate the water pump works....what is the connection between the two....Dave and wendy, 99u320.......
