I have had many problems blowing my bi metal fuse on my dishwasher. No talked to appliance people and they told me to replace the heating element so I did. Month later it blew again. They told me to replace the motor, which I did and it blew again. I noticed it always blew when it was winter and Inturned it on sanitize. In the winter I turn up the water heater so we can all shower with hot water. The temp increase along with the temp increase in sanitize mode made it too hot inside and it would blow the fuse. Just turn down the water temp and it is great.
