Description
Cause/Corrective Action
WASH, RINSE,
SPIN 1 time
Over Motor Temperature Error
Motor temperature is detected to be too high. Check that wash-
tub spins freely when empty. Check for overloading of machine.
Check motor harness for damage. Reduce agitation time and du-
ty cycle if rotate/pause times are very short and programmable.
Unpower to clear error. Replace drive board if error persists.
All LEDs 4 times
Fatal IPM Over Current Shunt Error
Check that washtub and motor spins freely. Unpower to clear er-
ror. Check the motor phase windings. Continuity should be uni-
form between phases L1 and L2, L2 and L3, L1 and L3. Replace
motor if not uniform. Replace drive board if error persists.
All LEDs 3 times
Fatal I2T Hardware Over Current Error
Check that washtub and motor spins freely. Rotor may be locked
up. Check the motor phase windings. Continuity should be uni-
form between phases L1 and L2, L2 and L3, L1 and L3. Replace
motor if not uniform. Unpower to clear error. Replace drive
board if error persists.
WASH, RINSE,
SPIN 2 times
IPM Over Temperature Error
IPM temperature is detected to be too high. Check that washtub
spins freely when empty, check for overloading of machine, re-
duce agitation time and duty cycle if rotate/pause times are very
short and programmable. Unpower to clear error. Check for lint
build-up on heat sink on drive board. Replace drive board if er-
ror persists.
All LEDs 2 times
Motor Not Connected Error
The motor or one of its electrical phases is not connected. Check
that the harness from the motor to the drive board is fully plug-
ged in on both ends and that there is no damage to the motor
harness. Make sure to push in the motor harness on both ends
just in case it is a little loose and not fully inserted. If the harness
looks fine and the error still occurs, try replacing the drive board
or harness. Unpower to clear error.
WASH, RINSE,
SPIN 3 times
Fatal Overload Current Detection
The drive stopped the motor because it is too hot. Let motor
cool, check for anything that may be preventing free rotation of
washtub and fix. If error persists, try replacing motor and/or
drive board.
WASH, RINSE,
SPIN 4 times
Back EMF Error
The phases of motor are decompensated. It is not possible to
control the motor. The drive stopped the motor. Cycle power and
try to run machine again. If error persists, try replacing motor
and/or drive board.
WASH, RINSE,
SPIN 5 times
Fatal Start-up Failure
After more than five occurences the drive turns off all outputs
and fatal error will be set. Cycle power and try to run machine
again. If error persists, replace drive board.
WASH, RINSE,
SPIN 6 times
Locked Rotor Failure
Locked rotor detected due to high motor current with low motor
voltage. Check for anything that may be preventing free rotation
of washtub and fix. If error persists, try replacing motor and/or
drive board.
All LEDs continu-
ous
Overcurrent Shunt Detection Circuit Fail
Error
Hardware failure. Unpower to clear error. Replace drive board if
error persists.
