My Kitchenaid dishwasher suffered from the faulty part that was involved in a lawsuit. Luckily ours didn't start a fire but started melting during use while we were home. Kitchenaid paid to replace the board portion. The thermal fuse blew after the warranty period (of course) and it worked fine for four months until I washed a sponge that fell down onto the heating element. A corner of the sponge was burnt off. I suspect that it would have started a fire if it hadn't used up all of the oxygen inside. The lights on the panel still lit up but after hitting start, the 'sensing' and 'add a dish' sensors wouldn't light up. We opened up the panel and removed and checked the thermal fuse, which was ok. After putting it back together, the 'sensing' and 'add a dish' light up after hitting start but then promptly shut off with a click. Is there something else that we can test? The dishwasher was working great previously and I am hesitant to replace it, especially with all the horrible reviews I've read for new dishwashers. Or is it time to just give in?

TIA
