SOLUTION
1. Check for blockages from the drain
pump to sump. Potential items: blocked/
stuck drain pump or drain hose check
valve, and/or plugged hoses.
2. Check the resistances of all connections
between the drain motor and control.
3. Disconnect the harness connections and
check the resistance of the drain motor
windings.
4. Remove the drain pump and check the
impeller by pulling and rotating it. If the
impeller pulls off easily, or turns freely
(normally there is some uneven resis-
tance), it is stripped. Replace the pump.
5. Disconnect the drain hose at the air gap.
Elevate the hose above the dishwasher
and fill with water. If water flows into
dishwasher, replace the drain hose.
6. Check the operation of the drain motor
by the control during Diagnostics.
1. Instruct the customer on the cycle selec-
tion.
2. Inspect following 3 screens. Remove the
dish rack and inspect the fine filter
screen. Remove the coarse filter and the
drain screen basket. Clean or replace as
needed.
3. Check for free and proper arm rotation
by operating the dishwasher and open-
ing the lid to check that the location of
the arms are not always in the same
place. If the arms are blocked, instruct
customer on stacking dishes. May also
have restricted flow/movement due to
misalignment or misassembly of the
spay arm water delivery system.
1. Check for water hardness. If hard, in-
struct the customer to use the maximum
detergent, or try pouring 1/8 cup of Glass
Magic into the bottom of dishwasher. To
clean the dishwasher, recommend run-
ning with 1/2 cup of white vinegar sitting
upright in the dish rack.
2. Check water hardness. If below 10
grains, instruct customer to use less
detergent.
3. Disconnect the drain hose at the air gap.
Elevate the hose above the dishwasher
and fill with water. If water flows into
dishwasher, replace the drain hose.
