Factors Affecting Performance
WATER PRESSURE
The hot water line to the dishwasher must provide
water pressure between 20 and 90 pounds per
square inch (psi).
Low water pressure may occur when laundry or
showers are in operation. Wait until water use is
reduced before starting dishwasher.
WATER TEMPERATURE
Hot water is needed for best dishwashing and
drying results. Water entering the dishwasher
should be at least 120°F (49°C) to give satisfactory
results.
To check water temperature entering the
dishwasher:
1 Turn on hot water faucet nearest dishwasher
for several minutes to clear cool water from
pipes.
2 Hold a candy or meat thermometer in stream
of water to check the temperature.
3 If temperature is below 120°F (49°C), have a
qualified person raise the water heater
thermostat setting.
IMPORTANT
Before starting a cycle, run hot water to clear
cool water from pipe.
