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 betore 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 reaching detergent dispensers.

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

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 drspensers 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 parl of the cycle.

3.Add Y, to % cup (120 to 240 ml) of citric acid crystals

(usually available in drugstores).

4.Close and latch door to complete cycle.

Permanent solution: Install on iron or mangcnese filter to home water supply.

Rinse flatware that is to stand for several hours before washing [use Rinse & Hold]. Clean stained items with silver polish and re-wash. Do not put stalnless steel and sliver

flatware In the same sllverware basket compartment. Direct contact between these metals can cause perma- nent damage to the sllver.

Remove spots with silver polish. Avoid spilling concentrated detergent on wet flatware.

,.			.
Remove tarnish with silver polish. Have silver replated.

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

dishwasher due to a plugged drain. The drain air gap is

NOT a part of the dishwasher and is NOT covered by the

dishwasher warranty. The drain air gap should be kept clean to insure proper draining of the dishwasher
