Factors Affecting Performance
Water Pressure
The hot water line to dishwasher
must provide water pressure
between 20 and 120 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 dishwasher
should be at least 120°F (49°C)
to give satisfactory results.
To check water temperature
entering dishwasher:
• Turn on hot water faucet
nearest dishwasher for
several minutes to clear cool
water from pipes.
• Hold a candy or meat
thermometer in stream of
water to check the
temperature.
• If temperature is below 120°F
(49°C), have a qualified
person raise the hot water
heater thermostat setting.
Important: Before starting a
cycle, run hot water to clear
cool water from pipe.
