Mus for Model Number GU2400XTPS7 My dishwasher has a time remaining digit display. It is showing "--" on the display. All keys work fine on the control panel. But pressing start button will not start the unit. Tried to turning off dishwasher breaker.. No help.. Ran diagnostic mode. Shows d3 and runs diagnostic cycle with no issues. Pressing cancel initiates 2 min drain cycle. I had the control panel (part# 3385741) already replaced from this site on 1/5/2014, because of a stuck/shorted key problem. Owners manual says -- means that door is not closed properly. Tested both door switches with multi-meter and both are good. Is it another problem with control panel again? Or is the logic board this time? Could it be thermal fuse? Please help.
Answer Hello Mus. You will need to repair the door switches or latch. The error is for bad door switches. Make sure the unit is level also. You need to look at the wiring on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
