1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all instructions.
5 Clean only with a damp cloth.
6 Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
7 Make sure that the available AC power matches the voltage requirements of this appliance.
8 Refer all servicing to qualified service personnel. Servicing is required when the appliance has been damaged in any
way or it does not operate normally.
WAR NING
Electric Shock Hazard
Failure to follow these instructions can result in electric shock, fire, or death.
1 WARNING–DANGER—Never allow children to play with, operate, or crawl inside the dishwasher.
2 Turn off the dishwasher before carrying out user maintenance on it.
3 If a component part is damaged, it must be replaced by the manufacturer, its service agent, or similar qualified persons

• To reduce the risk of injury, do not allow children to play in or on a dishwasher.
SAVE THESE INSTRUCTIONS
Features
How your dishwasher cleans
The dishwasher fills with water, covering the filter area at the bottom. Water is then pumped through the various filter and
spray arms, spraying a mixture of hot water and detergent against the soiled surfaces of your dishes and silver ware. Soil
particles are separated and go down the drain as the dirty water is drained and replaced with clean water. The number of
water fills is determined by the cycle selected.
Wash cycle selections
Cycle times are approximate and will vary with options selected. Hot water is necessary to activate dishwasher detergent
and melt fatty food soils.
An automatic sensor checks the incoming water temperature and, if it is not hot enough, the timer will be delayed to allow
for the water to heat for the main wash of all cycles.
Filter system
Your dishwasher has a multiple filter system which includes four separate filter meshes. It separates dirty water and clean
water into different chambers. The multiple filter system helps your dishwasher to get better performance with less water
and less energy.
Smart wash system
Your dishwasher has a smart wash system under the normal wash program which selects the wash cycle based on how
large and how soiled the load is, permitting your dishwasher to clean more efficiently every time. When a partial load of
lightly soiled dishes is placed in the unit, a short wash cycle is automatically selected. When a full load of heavily soiled
dishes is placed in the unit, a heavy wash cycle is automatically selected.
Adjustable upper rack
The upper rack of your dishwasher can be raised or lowered to accommodate loading dishes of varying heights in either
rack. The upper rack clearance height can be adjusted from 8" to 10" (20 to 25 cm). The lower rack clearance height can be
adjusted from 11" to 13" (28 to 33 cm). See "Loading the upper rack" on page 10.

Page 6
Loading the upper rack
The upper rack is designed for cups, glasses, small plates, bowls, and plastic items marked dishwasher-safe.For best
results, place the items with the soiled surface facing down or toward the center.Tilt them slightly for better drainage.
Note: Make sure that the loaded dishes do not interfere with the rotation of the middle spray arm, which is located just below the upper
rack. You can check this by rotating the middle spray arm by hand.
Loading the bottom rack
The bottom rack is designed to accommodate plates, bowls, saucers, and cookware. The adjustable rack lets you load items
up to 13” (33 cm) high. Large items should be placed along the edge, with the inside facing down, so they do not interfere
with the middle or lower spray arms or prevent the detergent dispenser from opening.
Adding a dish
CAUTION: TO AVOID BURN INJURY: Open the door slowly and wait until the spray arms and wash action stop. Hot water may splash out of
dishwasher. Failure to do so may result in injury.
Before adding dishes, refer to "Preparing and loading dishes" on page 9 for instructions on loading more dishes. Also see
information on Start/cancel in the "Controls and indicators" on page 8. To add or remove items after the wash cycle
starts: 1 Open the door slightly and wait a few seconds until the wash action stops before completely opening.
2 Add the item, then close the door firmly.
3 Press START/Cancel on the control pad and close the door within four seconds. The cycle automatically resumes.
Filling the detergent dispenser
1 Push the detergent dispenser cover latch downwards to open the detergent cup.
2 Add detergent (dry powder, liquid, or packets) to the cup.
3 Close the detergent dispenser cover.
Loading the silverware basket
The silverware basket is divided into three separate sections, which can be placed in either the upper or lower racks.
The amount of detergent required depends on the cycle selected and the soil level on the dishes. Refer to the following
table for the recommended amount.
Filling the rinse aid dispenser
Your dishwasher is designed to use a liquid rinse aid. The use of a rinse aid greatly improves drying performance after the
final rinse. Do not use a solid or bar-type rinse aid. Under normal conditions, the rinse aid will last approximately one
month. Try to keep the dispenser full, but do not over fill it.
1 Turn the rinse aid dispenser cap 1/4 turn counterclockwise and lift it out.

2 Add rinse aid until the liquid touches the indicated fill level. Do not overfill since this can cause over-sudsing. Wipe up
any spills with a damp cloth. The dispenser holds enough for 35 to 140 washes, depending on the dial setting.
3 Replace the cap and turn it 1/4 turn clockwise.
Factors affecting performance
Using rinse aid
Rinse aid greatly improves drying and reduces water spots and filming. Without rinse aid, your dishes and dishwasher
interior will have excessive moisture. In addition, the heated dry option will not perform as well without rinse aid. The rinse
aid dispenser, located next to the detergent cup, automatically releases a measured amount of rinse aid during the last
rinse.
If spotting and poor drying is a problem, increase the amount of rinse aid dispensed by rotating the dial to a higher
number. The dial is located under the dispenser cap.
If the rinse aid is low, the rinse aid light turns on at the beginning and end of the cycle indicating that it is time to refill.
Refer to "Filling the rinse aid dispenser" on page 11.
Water temperature
Hot water is required for optimum dish washing and drying results. Water entering the dishwasher should be at least
120° F (49° C) to achieve satisfactory results.
To check the water temperature entering the dishwasher:
1 Turn on the hot water faucet near the dishwasher and let it run for several minutes.
2 Hold a thermometer (a candy or meat thermometer will work) in the water stream to check the temperature. If the
temperature is below 120° F (49° C), have a qualified person raise the hot water heater thermostat setting.
Important: To make sure that the water entering the dishwasher is hot, run hot water from the nearest hot water faucet to clear cool water
from the pipe before starting the cycle.
Heat dry function
The heat dry function, when used with a rinse aid, enhances drying performance. If you do not choose the heat dry
function, items in your load that will not be completely dry at the end of the cycle.
Water pressure
For optimum performance, the hot water supply line for your dishwasher must provide water pressure of at least 20 psi
(138 kPa) and not more than 120 psi (828 kPa). You may experience low water pressure during high-demand periods, such
as when laundry or showers are in use while you are washing the dishes. To eliminate this problem, wait until hot water
demand is reduced before starting the dishwasher.
Maintaining your dishwasher
CAUTION: TO AVOID BURN INJURY: Allow the heating element to cool before attempting to clean the interior of your dishwasher.
Cleaning the stainless steel panel
Clean the stainless steel door and handle regularly with a soft cloth and standard household cleaner to remove the debris.
CAUTION: Do not use appliance wax, polish, bleach, or products containing chlorine to clean the stainless steel door.
Cleaning the control panel
Clean the control panel gently with a soft, lightly dampened cloth.
Cleaning the stainless steel inner door and tub
The tub is made of stainless steel. It will not rust or corrode, even if the dishwasher should be scratched or dented.
Clean the spots on the steel inner door and tub with a damp non-abrasive cloth.
Cleaning the filters
The filters are designed to collect debris and need to be cleaned monthly to maximize wash performance.
1 Remove the bottom rack.
2 Rotate the cylinder filter, then lift it out.
3 Lift the fine filter from the bottom of the tub.
12 13
Page 8
4 Take out the fabric filter.
5 Flush the filters by holding
them under running water.
6 Replace the fabric filter.
7 Replace the fine filter.
8 Replace the cylinder filter.
9 Replace the bottom rack.
Cleaning the door and tub gaskets
Clean the door gasket with a damp cloth to remove food particles regularly.
The inside of the dishwasher is self-cleaning under normal use. If needed, the
tub gasket can be cleaned with a damp cloth. Use a brush to clean the opening
in the end of the gasket.
Cleaning the air gap
If there is an air gap installed with your dishwasher, make sure that it is clean so the dishwasher will
drain properly. The air gap is not part of your dishwasher.
Before you clean the air gap, turn off the dishwasher, then remove the plastic air gap cover and clean
with a toothpick.
Protecting your dishwasher for long periods of non-use
Your dishwasher should be protected from freezing if you plan to leave it for extended periods in an
unheated place. Have a qualified person do the following:
To disconnect service:
1 Turn off the electrical power to the dishwasher at the supply source by removing fuses or tripping
the circuit breaker.
2 Turn off the water supply.
3 Place a pan under the inlet valve, then disconnect the water line from the inlet valve and drain it
into a pan.
4 Disconnect the drain line from the pump and drain the water into a pan.
To restore service:
1 Reconnect the water, drain, and electrical power.
2 Turn on the water and electrical power supply.
3 Fill the detergent cup and the rinse aid cup and run the dishwasher through a heated-wash cycle.
4 Check all connections to make sure that they do not leak.
