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) 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.
