Dlshes 6 lnterlor of dlshwasher yellow or brown

CAUSED BY

Water is not hot enough

Improper loading

Spray arm or arms not rotating freely

Not enough detergent or improper

detergent “0ld”detergenl.

Water pressure may

be low, dishwasher is not filling properly

Too much detergent in soft water

Inadequate rinsing

Iron or manganese in water

SOLUTION

Water temperature should be at least 140°F (6O”CJ. 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 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 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 ‘/4 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 an iron or manganese 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

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

Remove tarnish with silver polish. Have silver replated.

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.
