SOLUTION
Follow loading instructions.
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 the “To check water temperature”
section.
NOTE: In some cases, loads may not dry as
well when using the Hi-Temp Wash option.
Use recommended dishwasher detergents
only. Follow recommendations 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
detergent 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) (138 to 828
kPa) 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. To remove hard water film, see
“Removing spots and film” at the end of this
section.
Use the Hi-Temp Wash option. If needed,
turn home water heater up to ensure water
entering dishwasher is 120°F (49°C)
