(49°C) minimum. See recommended

procedure on page 14.

Use of incorrect

detergents

Use recommended dishwasher deter

gents only.

Incorrect amount of

detergent

Follow recommendations on page 11 for

amount. Heavy soil and/or hard water

generally require extra detergent.

Use of ineffective

detergents

Detergent should be fresh. Store in a

cool, dry place, preferably in an airtight

container. Discard lumpy detergent.

Insufficient fill caused

by low water pressure

Home water pressure should be 20 to 120

psi for proper dishwasher fill. A booster

pump on the water supply may be neces

sary if pressure is too low.

Cycle Takes

Extremely Long

Time

mended procedure on page 14.

Dishes Do Not Dry

Completely

Dishes do not drain

properly

Dishes must have proper water drainage.

Do not overload. Follow instructions for

loading dishwasher on pages 16-19. Use

a liquid rinse agent to speed draining.

Plastics

Some plastics, due to material, may

need to be towel dried.

Silica Film or

Etching (Silica Film

is a White Irides

cent Deposit;

Etching is a Cloudy

Film)

A water chemical

reaction with certain

types of glassware.

Usually caused by

some combination of

soft or softened water,

alkaline washing

solutions, insufficient

rinsing, over-loading

the dishwasher, and

heat of drying.

It may not be possible to prevent problem,

except by hand-washing. To retard this

process, use a minimum amount of

detergent but not less than one table

spoon per load. Use a liquid rinse agent

and underload the dishwasher to allow

thorough rinsing. Silica film and etching

are permanent and can not be removed.

Use the Air Dry option.

Black or Gray

Marks on Dishes

Aluminum items

Aluminum items should be loaded so that

they will not rub against dishes during

washing. Throw-away aluminum items

should not be washed in the dishwasher

because they may break down and cause

marking. Aluminum markings can be

removed by using a mild abrasive

cleanser.
