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 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
