Follow loading instructions.
If needed, turn home water heater up to ensure
water entering dishwasher is 120°F (49°C)
minimum. See the “Energy saving tips” section.
Use recommended dishwasher detergents
only. See the “Using the detergent dispenser”
section. Never use less than 1 tablespoon per
load. Detergent must be fresh to be effective.
Always store detergent tightly closed in a
cool, dry place.
Use only fresh detergent. Do not allow deter-
gent to sit for several hours in a wet dispenser.
Check dispenser for caked detergent. Clean
dispenser when caked detergent is present.
Home water pressure should be 20 to 120
pounds per square inch (psi) for proper
dishwasher fill. A booster pump on the water
supply may be necessary if pressure is
too low.
Never use soap or laundry detergents. Use
only recommended dishwasher detergents.
Use rinse agent to help prevent spotting
and filming. See the “Using the detergent
dispenser” section. To remove hard water film,
see “Removing spots and film” at the end of
this section.
If needed, turn home water heater up to ensure
water entering dishwasher is 120°F (49°C)
minimum.
