SOLUTION
Follow loading instructions on pages 6-9.
Use the HI-TEMP WASH option. If needed,
turn home water heater up to ensure water
entering dishwasher is 120°F (49°C) mini-
mum. See “To check water temperature” on
page 17. NOTE: In some cases, loads may
not dry as well when using the HI-TEMP
WASH option.
Use of incorrect, too
little, or ineffective
detergent
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.
Detergent cakes in
dispenser
Use fresh detergent only. Do not allow
detergent to sit for several hours in a wet
dispenser. Check dispenser for caked
detergent. Clean dispenser when caked
detergent is present.
Insufficient fill due to
low water pressure
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.
Spotting

arm due to high suds
Hard water or high
mineral content in

Never use soap or laundry detergents. Use
recommended dishwasher detergents only.
Use rinse agent to help prevent spotting

water film, see “Removing spots and film” on
page 20.
