Your dishwasher may have a heater built in to get the water to the temp
desired, mine does and it is older.

My washer specifies incomming water to be atleast 120 deg F. It is then
heated to 140 to 160 deg F depening on the cycle used.

I would assume most washers would have internal heaters to get the water hot
enough. The recommended setting for the house water heater is usually less
than 130 deg F.
