Had the Sears repairman here who replaced the control board then the outlet pump. Still tripping breaker after 1-2 loads. New guy came out and he discovered the wire from the house to Dw was hot on all three prongs (including the ground). Husband replaced wire from junction box to dw. No obvious breakage noted Ran a drain cycle then started a wash cycle. Ran for about 20-30" then tripped the circuit breaker. He took the cover off the breaker box and there is no obvious issues. Wiring is only 4 years old, dw is almost 6. Nothing has changed. Help!
