Whirlpool DU4099XX Dishwasher User Manual


 
For Best Results
Hot water is a must
For best cleaning and drying results,
water should be at least 140°F (60°C).
1. Turn on hot water faucet nearest the
dishwasher. Let water run until it is as
hot as possible.
2. Hold a candy or meat thermometer
in the stream of hot water to measure
the temperature.
3. If the temperature is too low, have a
qualified person raise the water heater
thermostat setting.
Quiet operating tips
To avoid thumping and clattering noises during
operation:
l
Make sure lightweight load items are secured
in the rack.
l
Make sure pot lids and handles, pizza pans,
cookie sheets, etc. do not touch interior walls,
interfere with the spray arm rotation or cover
spray tower.
l
Load dishes so they don’t touch one another.
NOTE: Keep sink drain plugs inserted during
dishwasher operation to prevent noise transfer
through drains.
Special tips
Remember, use your dishwasher only for the
job it was designed to do. Some items are not
dishwasher safe or may require special care.
Read these special tips for the following items:
Aluminum: Aluminum loses its bright, shiny
appearance and darkens in color due to minerals
in the water and the alkalinity of the dishwasher
detergent. Colored aluminum may fade.
TIPS: If washed in the dishwasher avoid
placing directly in front of detergent dispenser
where it could be sprinkled with undissolved
detergent, causing spotting, pitting, and
discoloration. Follow utensil manufacturers’
cleaning instructions.
China: Check manufacturer’s recommendations.
Hand-painted, metal-trimmed, and antique china
fade due to high water temperatures and alkaline
detergent solution in the dishwasher.
NOTE: Delicate, antique items should not be
washed in the dishwasher.
TIPS: Load china carefully. Do not allow
pieces to touch each other. Test one piece by
washing it daily in the dishwasher for several
weeks. Then compare it with the rest of the
set to see if colors have changed.
Crystal and decorative glasses: Crystal can
break from sudden exposure to high water temper-
ature. Metal trim and colorful decoration on glass
will fade in time when washed in the dishwasher.
NOTE: Delicate, antique items should not be
washed in the dishwasher.
TIPS: Load crystal carefully in top rack
only. Be sure to load a few larger items in the
bottom rack to reduce amount of force of
water spray reaching glassware from lower
spray arm. Use the shortest cycle.
Flatware: Salty and acidic food may tarnish
silver and stainless flatware if allowed to remain
on the utensils. A film may form on sterling silver
and silver plate items washed in a dishwasher.
This film is caused by reaction of silver with
chlorine in the detergent. Gold flatware is not
dishwasher safe. The adhesive used in some
flatware with hollow handles is not heat resistant,
causing the handles to come off in the dishwasher.
Wash by hand.
TIPS: Rinse flatware as soon as possible,
especially if it is not to be washed right away.
Dishwasher detergent may remove antique
finishes. Wash by hand. Tarnish and film
build-up can be removed with silver polish.
Cast iron utensils: The seasoned finish will be
removed in the dishwasher. Rusting will result.
TIPS: Wash by hand. To re-season, coat with
unsalted fat and heat in a slow oven for an
hour or two.
Plastics: Many plastics will have “Dishwasher
Safe” written on them. Some plastics are heat
sensitive and may melt or warp.
TIPS: If in doubt, try one piece. Place in
upper rack only. AIR DRY option provides
additional protection.
Non-stick finish utensils: Most can be washed
in the dishwasher.
TIPS: Follow manufacturers’ suggestions.
Wood: Many wooden items will crack and warp or
lose their finish.
TIPS: Do not wash cutting boards,
wooden salad bowls or knives with
wooden handles in the dishwasher.
Pewter or pewter-like materials: May streak,
discolor, and pit.
TIPS: To keep pewter at its very best, hand
wash with mild detergent.
