Allow more time when using AIR DRY Option, or use HEAT DRY. Plastic items may need towel drying.

Use care In loading aluminum utensils, especially any

llghtwelght foil container. Place so they do not touch dlshes. Remove black marks with plastic scouring pad and a mild abrasive cleanser.

Do not overload. Load glasses in the top rack only Load

between prongs, not over them. Glasses loaded over prongs will not be supported and may chip or break.

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 rt has filled for the wash part of the cycle.

3.Add % to % cup (120 to 240 mL) of citric acid crystals

(usually available in drugstores].

4.Close and latch door to complete cycle.

Permanent solutlon: Install an iron or manganese filter to home water suoolv.

PI-

Clogged

drain air

Some

plumbing

codes

require

use

of

a drain

air

gap

be-

gap

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

posslbility

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
