SOLUTION

Water temperature should be at least 14O’F [6O’C). Set water heater thermostat to a higher setting Run water at sink until hot before starting

Make sure dishes and glassware are 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 reachrng detergent dispensers.

Check spray arms to make sure they turn freely after load- ing Be sure a utensil has not prevented their turnrng.

Use more dishwasher detergent. Use detergent with high-

est avarlable phosphorus contenttespecially 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 rainbow hue on glasses. A rainbow hue IS the first sign of etching [corrosion of glass]. Reduce the amount

of dishwasher detergent. Use a detergent with a 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 are loaded properly to

assure adequate rinsing and draining. Do not overload.

Temporary remedy:

1 Set empty dishwasher for a “one wash” cycle.

2. Start dishwasher and unlatch door to stop it when it has filled for the wash part of the cycle.

3 Add Iq to I; cup (120 to 240 mL) of citric acid crystals

(usually available in drugstores).
