CARING FOR YOUR DISHWASHER
Cleaning the Pump and Spray Arms
Your dishwasher is designed to flush away all
normal food soils that may not have been removed
from dishes. However, certain foreign objects such
as fruit pits, bottle caps, and bones may collect in
the openings of the pump and should be removed
periodically to avoid clogging the drain system.
NOTE: Do not clean the dishwasher interior
until it has cooled.
1. Remove tower base by turning
counterclockwise.
2. Remove locknut and spray arm.
3. Clean out spray arm holes.
4. Clean in and around pump openings.
5. Replace spray arm and securely tighten
locknut. Spray arm should rotate freely.
6. Replace tower base.
Cleaning the Float
Clean the float to prevent it from sticking. The float controls the water
level in the dishwasher; sticking may cause an overflow or no water fill.
When removing float to clean, pull up firmly until it snaps out. To replace
float, push down until float locks into place. This will activate the float
switch.
NOTE: The float should move up and down freely for approximately
one inch when replaced on tube. Never run the dishwasher without
the float in place.
