What should the water temperature be?
To avoid personal injury or death, disconnect your appliance from its power source before you start any troubleshooting or repair work. Use caution when working inside any appliance.
The water temperature entering the dishwasher should be at least 120F, and up to about 140F. If you want to determine the water temperature as it enters the dishwasher, run the faucet nearest the unit into a cup or glass for a few minutes, until it gets about as hot as it's going to get. Insert a meat or candy thermometer into the cup and watch it until it doesn't go any higher. The water entering the dishwasher will be about this temperature.
You can try running this faucet for a few minutes before using the dishwasher. Then the unit will not have to pause as long while it heats the water to the desired temperature. You can also raise the thermostat setting on your hot water tank, but be very careful. You don't want to raise it too high and risk someone getting scalded by it being too hot.
