Drying with Energy Saver Dry option
Water temperature should be at
least 140°F (60°C). Set water heater
thermostat to a higher setting. Run
water at sink until hot before
starting, and/or use Hi-Temp
Washing option, if available.
Use more dishwasher detergent.
Use detergent with highest
available phosphorous
content...especially with hard
water.
Use only fresh dishwasher
detergent. Store tightly closed
container in cool, dry place. Discard
old detergent. Do not fill dispensers
until ready to start dishwasher.
Make sure dishes and glassware
are loaded so spray reaches all
surfaces and items drain properly.
Do not overload. Do not nest items.
Make sure large items do not block
spray from reaching detergent
dispensers.
Is a new solid rinse aid needed or
does the rinse aid dispenser need
filling? See instructions on page 7.
Drying without heat may result in
some spotting of glasses and silver.

they turn freely after loading. Be
