SOLUTION
See the “Loading Your Dishwasher” section.
Use the High Temp Wash option. If needed,
turn home water heater up to ensure water
entering dishwasher is 120°F (49°C) mini-
mum. See the “Cycle and option tips”
section.
NOTE: In some cases, loads may not dry as
well when using the High Temp Wash option.
Use recommended dishwasher detergents
only. See the “Using the Dispensers” section.
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. See the “Loading Your Dishwasher”
section. To remove hard water film, see
“Removing spots and film” at the end of
this section.
Use the High Temp Wash option. If needed,
turn home water heater up to ensure water
entering dishwasher is 120°F (49°C) mini-
mum. See the “Cycle and option tips”
section.
NOTE: In some cases, loads may not dry as
well when using the High Temp Wash option.
