FUNCTION CODE ERROR CODE
CAUSES
WHAT TO CHECK
7 - Wash Motor
1 - Motor not
running
Loose connection in motor circuit
and/or faulty wash motor.
1. Check operation of wash motor during diagnostics.
2. Unplug dishwasher or disconnect power.
3. Check resistances of connections in wash motor
circuit.
4. Check for loose connections or replace wash
motor.
Control motor drive circuit or sense
circuit
1. Unplug dishwasher or disconnect power.
2. If meter check of wash motor circuit shows normal
resistance and still not getting power to the wash
motor, replace control.
2 - Variable
speed motor
failure
Loose connection in motor circuit and/
or faulty wash motor.
1. Check operation of wash motor during diagnostics.
2. Unplug dishwasher or disconnect power.
3. Check resistances of connections in wash motor
circuit.
4. Check for loose connections or replace wash
motor.
Control motor drive circuit or sense
circuit
1. Unplug dishwasher or disconnect power
2. If meter check of wash motor circuit shows normal
resistance and still not getting power to the wash
motor, replace control.
8 - Inlet Water
1 - No water
No water to dishwasher
Verify water supply is turned on and supply line
adequate. Check for kinked fill hose.
Bowls or pots loaded or flipped upside
down and captured wash water
Instruct customer on loading. Refer to
Water leaking from dishwasher
Check for leaks under dishwasher.
Fill valve or water line plugged with
debris
Turn off water supply to dishwasher, disconnect
water line to inlet valve and inspect/clean the inlet
screen of fill valve and reconnect water line.
Fill valve electrical problem
Check other fault codes to see if F8E2 is also
recorded. See F8E2 description below.
Flow meter intermittent or failed
Check other fault codes to see if F8E6 is also
recorded. See F8E6 description below.
2 - Fill valve
electrical
problem
Loose connection in fill valve circuit
and/or open fill valve solenoid
1. Unplug dishwasher or disconnect power.
2. Check resistances of fill valve solenoid and all
connections in the fill circuit with meter.
3. Fix/replace open connection/part.
Open fuse on control to fill valve
Refer to “Fuse Service and Resistance Check” in
section 3.
Faulty fill valve drive circuit on control 1. Unplug dishwasher or disconnect power.
2. Check resistances of fill valve solenoid and all
connections in the fill circuit. If all connections and
solenoid measure good, replace control.
