Motor went out so replace new pump motor assembly. Hooked up, turn timer on, motor comes on water didn't fill. Got 120 volts at the heater, 11.5 volts to the water valve, 9.9 volts to the float switch. Ohmed the float switch and it was all over the place so replaced with new one. So should I replace the water valve next? It's hard wired from the breaker and the wires showed 120 volts but were a little corroded. Any Help appreciated!

So should I replace the water valve next?
No. By the sound of it the valve is not getting power so it is not the problem.
To confirm this measure from one side of the valve (WH on the wiring diagram) to the far side (timer side) of the float switch.
If not 120 volts when it is supposed to be filling with water then it is probably either the timer or you have a bad wire going from the timer to the valve.

If the unit filled OK before the motor change I would check the wires for continuity.

Thanks denman, I tested the water valve with a different plug and hooked up to the water line and no water would come out. The water line works fine and the valve wasn't clogged. So I'll be replacing it anyway. I'll check for bad wires and if I find none it's on to the timer next!
