Question and Answers


How do I diagnose the failure of my GE Profile Dishwasher that has no power?


In order to diagnose the failure will require checking and verifying the voltage supply at the dishwasher junction box and where it connects to the electronic control board and sequencer. The door switches will also need to be checked for proper operation too. NOTE: I do not recommend checking and verifying voltages unless you have experience and feel safe and confident in doing so, otherwise I recommend calling a service technician to diagnose and repair your dishwasher. The junction box is located under the right front corner of the dishwasher. You will need to remove the lower access panel in order to access the junction box cover. You will also need to separate the inner door panel from the outer panel in order to access the control board and sequencer. I added an image below with the wiring circuit and instructions on how to separate the inner and outer door panels.

The voltage supply should be tested and verified at the junction box first and then tested and verified on the control circuit board at terminal connector (D). There should be 110-120 volts when measuring across D3 and D4, D3 and D2 and voltage should be present when measuring across terminal 5 at the Black plug #B (black wire with white stripe) and D3.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Thanks much Joey S for the info. I have the same problem. I checked the voltage supply to the unit is about 123v using a Multi-meter. I will need to verify the voltage as you mentioned. Does it has a fuse? If it does, I hope it is just a burned fuse. They should have a fuse to protect the device, I hope. The image you attached is way too small to view. Could you please upload a bigger version or a PDF? Thanks much.
