Al for Model Number 665.17369301 I noticed some smoke coming through the door handle of the dishwasher, when I opened the door, the dishwasher would not shut off. Cancel worked, but had to push a second time after drained to stop. Pulled the control board after securing the circuit breaker and found significant scorching. The terminal for the white/red wire at P6 pulled off the board with the connector. I didn't find any shorts to ground on any of the wires. What else besides the control board should I look at? By the way, I've had the dishwasher for 10+ years without any problems.
Answer Al, The P6 terminal (wht/red wire) is the heater element circuit(power/voltage out) You'll want to check the wiring to the thermostat and heater element for loose connections, corrosion etc, causing an increase in the amperage draw. You may want to test the resistance of the circuit. At the control board, disconnect the P6 connector and the white wire on the P7 terminal, across the two wires you should have a resistance reading of 10 to 30 ohms +/- 10% if all's OK.
