I had an old GE portable dishwasher that I converted to be a builtin. After a couple years of use, i.e., normal vibration, the insulation on the power supply feed to the unit wore through, shorted to ground, and started an electrical fire under my countertop. Eventually the wood countertop caught on fire and started to bubble the formica above the builtin. The entire house filled with smoke. Luckily we were home at the time. I had to literally rip the unit out of its cabinet recess and get up underneath the counter to extinquish the fire. I discovered later that the supply breaker to the unit was defective, i.e., failed to trip properly.
To prevent the same insulation wear on the replacement dishwasher, I used a section of flex to encase the power supply line. |
