Hey all-
unit started running dry recently. I got a new water inlet and float switch to fix the most typical issues. Turns out they weren’t the issue! I put a digital probe to AC-Volts/200 and plug into the water inlet connector. I never see the 120V as it cycles so I actually have no juice. The Yellow wire I assume to be the power and the whites are the neutral.
The Yellow is run over from the float switch. What’s a good way to test the juice coming to the switches. Can I bypass anything to the get the inlet to start working?

I do not have access to tech info on this unit so the above is the best I can do.
You will have to double check every thing.
Check for 120 volts across the valve and fill switch combo.
So one meter probe on the not yellow wire of the water valve and the other meter probe on the noy yellw wire of the float switch.
If still nothing
Remove power from the unit and use resistance to check the valve winding.
Should be around 1000 ohms.
Now check for this reading at the control board connector .
If you get the same reading then you know that the wiring down to the valve/switch combo is good and the most likely culprit is a bad control board.
