GE dishwasher not filling enough
Posted 29 April 2012 - 02:48 PM
So I'm trying to determine why I don't have enough water.
I have replaced the supply line from the plumbing stop valve under my sink to the fill valve of the dishwasher. (The previous pex line appeared narrowed where the compression rings went around it.) That may have improved things slightly, but the arms still don't spin rapidly unless I add water. I also disassembled the brass elbow into the fill valve and removed the fill valve from the machine to make sure the screen was not obstructed. A couple little pieces of junk came out, but not enough to obstruct the flow.
My guess is I have one of two problems:
1. Controller is not leaving fill valve open long enough before starting cycle
2. Fill valve is not opening all the way or is somehow internally obstructed so it doesn't properly fill in the time allotted.
I cannot find the tech data sheet between the tub and sheet metal, so I'm not sure get in to mess with the controller.
(Before discovering that adding watter made the arms spin, I also disassembled the motor and found the blades and chopper to be clear and in excellent contition, cleaned the screen basket in the bottom of the tub, and disassembled the check valve between the drain and the drain pump and cleaned it.)
Looking forward to a guru solution.

The micro switch may have a bent actuator arm not allowing a full fill.
Remove the toe kick panel and locate the fill valve switch.
Make sure the float stem is not binding.
Set the machine to start a cycle while watching the float stem rise.
Adjust the metal actuator for more fill.

Here's a picture of the underside of the float switch behind the toe kick.
You can reach in and push the circle part up, actuating the switch. So I started a cycle and watched the switch. The water flow stopped at 50 seconds, and the switch did not move at all during that time. Could you tell me what I might try to adjust?

But I don't see why I would replace the float switch when the float switch is not what's turning off the water. The switch never activates, and water never gets anywhere near it, but yet the fill valve shuts off after 50 seconds every time. Want to tell us why you think that will fix it, jumptrout?

If you are not filling within the 60 seconds(50) should be sufficient the water valve could be weak or restricted or the float switch is out of adjustment(dirty and sticking) inside.
Look at the float switch and follow the pink wire to the water valve.
That is the L-1 power in to the water valve.
Use your volt meter to time the power flow at the switch and the valve.
