Question by Papi: can a too-hot water heater damage a dishwasher and washing machine?
I had a hot water repair guy turn my hot water heater way up, saying that was why it wasn’t starting. Then my dishwasher latch stopped staying closed and the steam damaged my counter-top,and on the same day my washing machine left dark spots on my white laundry! When I measured the temperature of the water it was 170 degrees with the meat thermometer.
Answer by ASHLEY
Dishwashers are cold fill only and should not be attached to the hot water pipe.
Washing machines only use hot water when the program exceeds 60 degrees C.
It sounds as if the machines are either plumbed in wrong or that it’s coincidence.
