GE dishwasher won't fill (intermittently)

(1/1)

g3_ultra:
My GE dishwasher doesn't fill when turned on. I checked the float and it seems to be OK. Good spring action and clicks on and off. I put my meter leads on the fill valve coil wires and sure enough, no voltage when it's turned on and not filling. I finally got it to fill, and of course it reads 120V when it's filling. The next time I went to run it, same thing again; no water. Seems like maybe a bad connection or broken wire. Anyone seen this problem before?

Model GSD600G-01

Repair-man:
I have seen this problem before and it usually turns out to be a timer issue. You see, the timer on the GSD models sends voltage to the water valve only for a brief 2-minute time at the beginning of every wash and rinse program. If you manually advance the timer, it may skip the fill, as the contacts are somewhat delicate and difficult to initiate this way. When I test one of these models, I turn the timer ever so slightly until it barely comes on, then wait with my meter until the fill signal starts up about a minute later. If you try to advance it to fill, it may miss out. When it starts skipping the fill occasionally, replace the timer.

Wiring issues can occur, but are rare on this model. The timer on this model can be easily damaged by attempting to turn it counterclockwise instead of clockwise to set. Usually, timer failure occurs on this model due to little hands meddling with Mommies dishwasher, but it can occur with no help at all just from years of use.  The GSD is a very old machine.

You can try spraying the timer with a non residue cleaning spray, just turn the timer while spraying.

You mean like contact cleaner?

No, get non residue contact cleaner at Lowes.
