Dishwasher Correct Water Temperature

Water entering the dishwasher must be at least 120 degrees Fahrenheit and not more than 150 degrees Fahrenheit for the best cleaning and to prevent damage to the dishes.

You can check your water temperature with a candy or meat thermometer: Turn on the faucet nearest the dishwasher, place the thermometer in a glass and let the water run into the glass until the temperature stops rising (one minute or more).

If the water is not hot enough, the water heater may need to be adjusted. It is always a good idea to let the water run in the sink until it gets hot before starting the dishwasher. This makes sure the dishwasher is starting out with the hot water it needs for good wash and dry performance.

Note: If this is a new installation, confirm that the dishwasher is connected to the hot water line, not cold. Turn on the hot water at the sink, then feel the water pipes under the sink - make sure that the dishwasher water line is connected to the pipe that feels warm or hot.
