- The filter that is fitted near the bottom of the dishwasher should be cleaned regularly.
The dishwasher owner's manual gives instructions on removal and cleaning of filters.
If there are holes in the filter, replace it to protect the pump and motor seals
from particles that may be in the dishwasher.
- Clean the small holes in the spray arms of the dishwasher occasionally as they may
become clogged with dirt and debris from time to time. This will enable the dishwasher
to work more efficiently.
Problem: The dishwasher will not drain.
1. Inside the dishwasher at the bottom of the unit, there is what looks like an
upside down cup. This is the float or pressure switch that should move up and down
freely. Gently attempt to move it; if any large food particles, glass, plastic,
etc. have become lodged under this switch, remove them so the unit can function
2. If the float switch is OK, there may be a clog in the air gap. This is the hose
that runs under the sink from the dishwasher to the silver cap on top of the sink.
There may be an obstruction in the line or in the air gap itself. Remove the silver
or plastic cap that exposes the air gap. If you see an obstruction (i.e., food particles,
etc.), remove them. If no obstruction is visible, the top of the air gap should
pop or unscrew. Remove it to find out if you can see any other obstruction. If no
obstruction is visible, invert a plastic cup over the air gap opening (making sure
the cup is suctioned tightly to the sink) then advance the dishwasher timer to the
drain cycle to start pumping water through the line. If the obstruction is in the
line, it should be pressurized out of the air gap opening. Be sure to keep your
hand on the cup to prevent the water pressure from pushing it out of place. If the
water runs through the air gap, shut off the dishwasher and reassemble the air gap.
3. If the disposal was recently replaced, the installer may have failed to remove
the plug on the side of the disposal where the drain hose connects, preventing the
unit from draining. This plug normally requires a special tool and can be rather
difficult to remove. To prevent damaging the unit, contact the installer directly
to remove the plug.
Problem: The dishwasher is not cleaning dishes properly/ is leaving behind food particles or soap.
Food and soap properly dissolves if the water temperature is above 140 degrees. Try increasing the temperature on the water heater or run the faucet at the kitchen sink until it comes out hot prior to starting the dishwasher.
