Came home yesterday after my writing session with a few grocery purchases, including a sandwich for lunch. When I entered the kitchen, my wife said, “The dishwasher isn’t working.”
The dishwasher is a GE Profile. I think we bought it about six years ago. “Okay let me eat and research and I’ll get on it.”
So I did those things and then ran the dishwasher on my own, studying the symptoms. Which were:
- lights come on; program selected; door closed; WASHING displayed
- pump runs to empty dishwasher
- time passes, and the machine is quiet
- WASHING display goes off; all lights go out
- I opened the dishwasher; bone dry; no water was entering
I pull and clean the fine and macro filters. That’s an easy first step and one I’ve done several times before. Neither are blocked or very dirty because I just cleaned them at the first of the month. They’re usually the culprits because unhindered water circulation and solid water pressure is needed for the dishwasher to properly operate and clean.
The manual is read. Nothing useful emerges. To the net!
The net suggests the overflow valve might be stuck. Just lightly tapping it with a wooden spoon might free it. Or it might be the recirculating pump.
I spend time looking for the overflow valve and can’t find it. I search for more information on the net but nothing helpful is found. I finally reverse my thinking and search, “Do all dishwashers have overflow valves?” No, more modern dishwashers don’t have ’em. Great; that was a lot of wasted time.
I put the machine into its diagnostic mode and run through those, confirming the dw isn’t filling with water.
More searching leads me to the inlet valve and how to reach, remove, and test it. The water feed to the dishwasher is turned off, as is the power via the circuit breaker. The pieces I need to access are behind the kick panel. It comes off easy enough but tight clearances and sharp edges make removing the inlet valve a tedious and time-consuming process. Some bleeding is involved but I get it off. The valve coil is tested for continuity and is good. They don’t recommend cleaning the inlet valve because of seals and tolerances. I resign myself to ordering a new one but on a whim, I gently shake the valve, thinking the valve is stuck and maybe shaking it will release it. Why not, right?
After replacing the inlet valve, turning on the water and powering up, I now have trickle of water. WTAF? I listen. The dishwasher stops and tells me on the panel, H2O.
Well, heck, it wasn’t showing that before. I confirm the water is on and no lines got kinked while I was messing around in the underside and try again. Same-oh.
Following nebulous thoughts, return to the net to search for other problems and find a video which suggests, pressure sensor. Attached to the recirculating pump, it’s easily accessible since I already have the kick panel removed. I pull the sensor, follow the cleaning instructions and re-install it, power back up, etc.
Works like a charm.
I’m astonished. I’m not mechanical, so I’m always pleased when I can find the instructions and guidance from wherever I can and repair something. It’s like a small victory in a big universe when I can declare something ‘fixed’.
Especially when I’m the one who did the fixin’.
