Joe for Model Number GDT580SMF7ES Dishwasher control doesn't light up unless I push START and SELECT CYCLE at the same time. Then 817 comes up on the display and all lights light for a few seconds. Then the display and lights go out and the LOCK CONTROLS light comes on until I press something on the control. Then that light goes out too. The ui control board has been changed with no change. I suspect the main control board. What do you think?
Answer Joe, at the main control board at the bottom, there will be an LED that might be flashing once the control housing is opened. If it is flashing 7 times within 3 seconds, then there was an overcurrent issue. In this case, the heater WD05X30818 would need to be replaced and the software would need to be updated using the SUM module WD98R2327901. Read More...
