WP BUILT TT DW CIRCUIT BOARD FIRES
We have seen many of these boards that shorted and burned, I feel that it is a board overheating and burning. I have seen no evidence of water causing the problem as this part [ as you would expect ]is very well protected from water leaks from the machine or spilled water from the counter top above.
Unfortunately major appliances have been having minor shorts and electrical fires since electricity came into homes 100 years ago. The problem today is that too much plastic is used around the electrical parts and when things go wrong it can result in a BIG problem and can more easily cause a house fire. Properly protecting the electrical parts of appliances would go a long way to minimizing any danger when things go wrong. I have never liked plastic control panels on appliances, A high school friend had their house burned down by an early 1960s Westinghouse TL portable DW when water got on some electrical parts and the plastic control panel went up in a blaze and set the kitchen and house on fire.
This is another big reason why I don't want a DW, washer, dryer etc that runs for three hours at a time, I also don't want one that is so quiet that you are unaware that it is even on. Major appliances do pose some danger of fire, flooding, explosion, injury and death from electrocution.
