Appliance Repair Wisdom for the Ages

Went on a dishwasher service call the other day. Complaint was that the dishwasher was completely dead. The customer had already verified that the circuit breaker wasn't tripped.

First thing I always do on a dead dishwasher complaint is to verify that power is available at the power junction box in the dishwasher. I removed the kickplates, then open the junction box cover and, SHAZAAM! that's what I saw. It's a wonder the breaker didn't trip!

Invariably, I get asked, "What caused those wire connections to burn?" Loose electrical connections generate heat-- these wire nuts were probably not installed correctly and loosened enough over time to cause the connection to burn. In this case, the connections were contained by a grounded metal box, so there was little fire danger.
