I have an old GE Profile dishwasher (PDW9280NOOSS) that started having some issues a few months ago where we would start the washer and it would not run. We would then start the washer again and it would work. Unfortunately, now when we start the dishwasher it will run about 1 minute and fill the bottom with about 1 inch of water and then stop (and the start light on the control panel goes out). Any ideas what I should check/replace to get it working again? Thanks, Ken

Just wanted to give you an update on some testing I’ve done. I tested it in “Service Mode” and it seemed to pass all 5 tests (Heater fan, water valve, detergent cup, auxiliary pump, and main pump. I then ran the “factory test mode” and it seemed to stop at “main pump”. Can I assume the main pump has gone bad? If so, could I use this quick fix at https://www.youtube.com/watch?v=wiKm_bMq6P4 or should I just replace the main pump? Thanks, Ken

Ken, I don’t know that a quick fix is going to be permanent. It would be something you certainly can try. Let me know how it turns out.

Thanks! I’ll give the quick fix a try this weekend and let you know the results

Sorry for the delay in getting back on this. I tried the “quick fix” in the video link above but the main circulation pump motor was not locked at all and moved freely. I also tested the motor with a multi-meter and it had .021 continuity and an ohm resistance of .018. It is supposed to have a resistance of 10 ohms. Am i correct that the .018 resistance reading is much too low and the circulation motor likely has a short and needs to be replaced?

Another update on this. It turns out I may have had an bad multi-meter. I bought a new multi-meter and tested everything I could think of on the dishwasher. The circulation motor has continuity and a resistance reading of 18 (supposed to have 10) so I’m assuming the motor is okay?

Here are the readings for the rest of the items tested. Does anything stand out as an issue? I’m new to using a multi-meter so wanted some expert opinions.

  1. Door interlock beeps when I close it. Assuming it works.
  2. Water intake valve. No continuity beep but has resistance of 1.105 (supposed to have between 725-1200)
  3. Heating element. Continuity beep and has resistance of 15.3 (supposed to have 17)
  4. Vent louver motor. No continuity beep and resistance of 12 ( not sure what resistance should be)
  5. Drain pump. Continuity beep and resistance of 25.2 (supposed to 16)
  6. Detergent module. No continuity beep and resistance of 2.32 (supposed to be between 1200-2800)
  7. Vent blower motor fan. No continuity beep and resistance of 65.5 (supposed to be 65)
  8. Turbidity sensor- Continuity beep and resistance of 25.31 at room temperature (should be 9.9k at 75 degrees) I also cleaned it as well as cleaning entire sump, particle filters, etc
  9. Flood switch- No continuity beep and resistance of 000.2 (but the resistance reading also “jumps around a lot” and then settles on 000.2). Not sure what resistance should be.
  10. Transorb. No continuity beep and resistance of 1.2 (should be 100k or higher)
  11. Main Control Board. J1- Door Interlock Switch (no continuity beep and 222.5 resistance), J2- Heating Element, Circulation Pump, Drain Pump, Fan, Water Valve, Detergent module (continuity beep and 000.1 resistance) J3- Turbidity Sensor (no continuity beep and 7.23 resistance) J5- Vent Louvre Motor (no continuity beep and 12.00 resistance J7- Membrane Keypad Ribbon Cable connector (no continuity beep and 39 resistance) J8- LED ribbon cable connector for 3-digit display (no beeping continuity and 002. resistance)
  12. I have also attached the “tech sheet” in case you need it.

Thanks,

Ken

Just to give you an update on this. I installed a refurbished control board and a new water inlet valve and the dishwasher now runs part way through the cycle beyond just filling with water. However, it does not complete the cycle. It left a pool of water in the bottom after it stopped. I then pressed the start button again and it drained the water. The keypad also does not allow me to enter “factory reset” mode with this control board. Any ideas what I should try to fix my dishwasher?
