SOLUTION
Follow loading instructions on pages 6-9.
Use the HIGH TEMP WASH option. If
needed, turn home water heater up to ensure
water entering dishwasher is 120°F (49°C)
minimum. See "To check water temperature"
on page 21. NOTE: In some cases, loads may
not dry as well when using the HIGH TEMP
WASH option.
Use recommended dishwasher detergents
only. Follow recommendations on page
10 for amounts. Never use less than one
tablespoon per load. Detergent must be
fresh to be effective. Always store detergent
tightly closed in a cool, dry place.
Use fresh detergent only. Do not allow deter-
gent to sit for several hours in a wet dis-
penser. 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
recommended dishwasher detergents only.
Use rinse agent to help prevent spotting
and filming. See page 11. To remove hard
water film, see "Removing spots and film"
on page 24.
Use the HIGH TEMP WASH option. If needed,
turn home water heater up to ensure water
entering dishwasher is 120°F (49°C) minimum.
See '3-0 check water temperature" on page 21.
NOTE: In some cases, loads may not dry as
well when using the HIGH TEMP WASH
option.
Use recommended dishwasher detergents
only.
