DW trips cicuit breaker (by 2 users)

I have seen a lot of these older dishwasher break the wires running up to the timer. the break right near the bottom of the door where they flex when you open and close it. I would turn of the power, remove all the torx screws along the inside edges of the door, as well as the 2 on the bottom edge of the door facing up (you cant see them, just gotta feel around for them) and loosen the 2 on the top of the door near the latch ( so you can tilt the control panel out to remove the outer door) follow the wires from the timer down to the bottom of the door and see if any are broken or missing insulation. If not, take the bottom panel of the dishwasher as well and locate the 2 terminals hooked to the heater and check them with an ohmeter to see if they are grounded to the frame of the dishwasher. the dishwasher may be doing a heated rinse just before the dry cycle even though you have low temperature and no heated dry selected, so the problem may still be the heater. Good Luck!
