Whirlpool DU8900XT manual Inadequate rinsing

PROBLEM

Dishes not washing clean

Cloudy film on glassware, etching - permanent corrosion

CAUSED BY

Water is not hot enough

Improper loading

Spray arm or arms not rotating freely

Not enough detergent or improper

detergent

“0ld”detergent

Water pressure may

be low, dishwasher IS not filling properly

Too much detergent in soft water

Inadequate rinsing

SOLUTION

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 WASH Option.

Make sure dishes and glassware ore loaded so spray reaches all surfaces and items drain properly. Do not ov- erload. Do not nest items.

Make sure large items do not block spray from reaching detergent dispensers.

Check spray arms to make sure they turn freely after lood- ing. Be sure a utensil has not prevented theirturning.

Use more dishwasher detergent. Use detergent with high-

est available phosphorus 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.

If water pressure is low, do not use water for other purposes while dishwasher is running [to assure correct fills].

Check for rarnbow hue on glasses. A rarnbow hue IS the first sign of etching [corrosion of glass]. Reduce the amount

of dishwasher detergent. Use a detergent with 0 lower phosphorus content

If water pressure is low do not use water for other purposes

while dishwasher is running [to assure correct water fills). Make sure dishes and glassware ore loaded properly to

assure adequate rinsing and draining. Do not overload.

gap

Allow dishwasher to complete cycle.

Some plumbing codes require use of a drain air gap be-

tween an undercounter dishwasher and the drain system of the house. The air gap is usually located above the sink or on the top of the counter near the dishwasher to prevent the possibility of water backing up from the drain into the dish- washer due to a plugged drain. The drain air gap is NOT a

part of the dishwasher and is NOT covered by the dish- washer warranty. The drain air gap should be kept clean to ensure proper draining of the dishwasher.
