Green light on front of dishwasher blinking 7 times and dishwasher shuts down. I ordered replacement heating element and control board but when I opened the door panel I noticed that some of the wiring looked burned and the insulation on the door had melted in those areas. The original control board part number is 8564546. The new part number that came with the heating element kit is 8564543. Two questions: Is the new part number correct? Will replacing the control panel eliminate the burning wire issue?
Answer Hello Swtsgg,
This is a heating circuit failure fault code. If the harness was melted into the black insulation material, as per the manufacturer, the harness and the inner door liner will have to be replaced. This may correct the heating circuit issue since the wiring can conduct through the insulation. The insulation has been changed to prevent this issue from recurring. I would have provided part numbers but could not without your units' model number from its' I.D. tag. I would not replace the control until the harness and door liner have been replaced.
