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 setting. (Heating cold
water takes longer.)
• Turn on the power, run the Cancel
cycle option to remove the residual
water, then run the Quick cycle using
detergent but with the dishwasher
empty.
• Clean the filter and the interior
according to the Maintenance section of
the owner's manual.
• 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 damage
your appliance.)
• Adjust hose or clear blockage.
• Select correct cycle based on soil level
and type of dishware being washed.
• Check water supply connection or water
heater setting.
• Use recommended detergent.
• Water pressure should be between 20
and 80 psi.
• Clean the spray arms.
• Make sure dishes do not block spray
arm rotation or interfere with detergent
dispenser.
• Clean filters.
• Use less detergent and use a rinse aid
to minimize the problem.
• Reposition the dishes.
