My user interface (as you call it) was having a very difficult time working right. I would push the buttons on top and it just wouldn't start the dishwasher and some of the lights wouldn't light up. I replaced the part and the dishwasher worked for a month perfectly. Then out of the blue, none of the buttons would work at all or even light up. I got another user interface and it won't work any buttons either. I am thinking that isn't the problem ? I did a test with a power finder and it chimes as I get close to the start buttons, which makes me think power is getting up to the board.
Answer Hi RHY. Use a volt/ohm meter part #@ TJMA-DM1 to assist you in your diagnostics. It will be advantageous to find the supplied tech sheet inside the cabinet to aid you in the diagnosis. It allows you to put the unit in a diagnostic mode which brings up fault codes and tells you which circuit needs assistance. It is located in the control panel area or the lower kick plate. Use the door striker to trip the door latch to make sure you are getting full 120 volts to the control board through the thermal fuse part # 8193762. A very common board lost voltage power issue that now is upgraded. If not back up and check the door switches to insure you are not loosing voltage there. If you still do not have full voltage then back up to the lower power junction box and make sure the connections are tight at full supply voltage there. Use the breaker for safety. As you have a solid copper supply line and the dishwasher has a solder tinned stranded wire, it is common the stranded wire will lower under the wire cap twisting effect to the bottom of the solid wire and not allow the proper total stranded wire length to tighten with the solid wire together. Knowing this is an importance that the unit can get apparent voltage but will not draw the correct amperage needed under a load and starve a control board and prematurely ruin it. It all can go back to a improper installation issue. Make sure the 14 pin control board is connected fully and that all female spade connections will contact the solid board pin tightly. Use a pick tool and a magnifying glass to close the wire connector female spade connectors. Let us know how to help further if so needed. Thank You.
My dishwasher has power but will not start. The buttons on the control panel light up green but the dishwasher will not start. The door clicks closed as usual so I don't think it's the lock. The "rinse only" button is blinking and will not go out even if I press the cancel button.
Is it the control panel or user interface?
Answer Hi John. DISHWASHER : Flashing green light means the heating circuit or the drain circuit/hose has an issue. Ohm out the heater to see if it has continuity and not open. Make sure all wires are connected tight and not bad.Heater part # 8194200.The thermistor part # 8269208 will tell the board if the heater has to be initially used to increase wash temperature to at least 120°. Are you running the sink water hot while loading the dishwasher? Is the water heater set to at least 120°? Is the drain pump clogged or inoperative part # 661658? Make sure the drain hose is not clogged at the sink or the sink clogged. Use the lower kick panel tech. sheet or behind the control panel. There is a tech.sheet to aid in a field service test to aid after you have checked these issues. Make sure the door neutral and line switches are working properly. Let us know if we can assist further. Thank You.
