long
Odor
Water remains in tub
after completion of cycle
Spots and filming on

Possible Causes
Door is not completely closed.
Power supply or power cord is not con-
nected.
Fuse is blown or circuit breaker tripped.
Dishwasher is connected to cold water.
The previous cycle was stopped before
completion and residual water remains in
the dishwasher.
There is food in the bottom of the unit or in
the filter.
Unwashed dishes are left in the unit for a
long time.
Drain hose is kinked or clogged.
Low water temperature.
Wrong amount of detergent used.
Overloading.
Improper loading.
Insufficient water pressure.
Insufficient detergent.
Rinse aid dispenser is empty.
Extremely hard water
The best way to eliminate spots on your dishes is to install a whole house water softener in your home. If
a water softener is already installed or you do not plan on installing one, try adding the "Extra Rinse" op-
tion as part of the wash cycle to help minimize this condition. To add an extra rinse to the cycle, select the
wash cycle and then press the RINSE button.
NOTE: Selecting "Extra Rinse" will increase cycle times and water usage.
To remove hard water build up in the tub
Remove all dishes, silverware and silverware holder from dishwasher. Only racks should remain in tub.
For best results, use citric acid powder (can be found in canning sections of most grocery stores or on-
line). Measure 6-8 tablespoons (90-120 g) of citric acid powder. Fill main wash compartment with mea-
sured powder. Place remaining powder in shallow bowl and place bowl in lower rack. Add warm or hot
water to bowl and stir to dissolve citric acid powder. If you cannot find citric acid powder, pour approxi-
mately 1 ¾ -2 cups (400-500mL) of white vinegar into shallow bowl and place in lower rack. Run Normal
cycle with Extra Rinse and Sanitary options.
DO NOT USE DETERGENT. After cycle is complete, remove bowl and run a quick cycle to clean tub of any
remaining vinegar or citric acid.
Solutions
Make sure that the door is completely closed and
latched.
Connect the power supply or cord properly.
Replace the fuse or reset the circuit breaker.
Check the water supply connection or water heater set-
ting. (Heating cold water takes longer.)
Turn on the power, run the Cancel cycle option to re-
move the residual water, then run the Quick cycle using
detergent but with the dishwasher empty.
Clean the filter and the interior according to the "Care
and Cleaning" section of the owner's manual.
Run an empty cycle with detergent, or run an empty
cycle with one cup of white vinegar in a dishwasher safe
glass or bowl placed on the upper rack.
(Vinegar is an acid, and with constant use it could dam-
age your appliance.)
Adjust hose or clear blockage.
Water supply should be at least 120°F for best wash
performance.
Use the recommended amount of detergent.
Do not overload the dishwasher.
See the Using Your Dishwasher section.
Water pressure should be between 20 and 120 psi.
Add the recommended amount of detergent. See the
Using Your Dishwasher section.
Refill rinse aid dispenser.
