MAH22 – MHN30 – MHN33
0F
Oversuds detected during cycle, and washer was not able to
resolve an unbalance condition detected during final spin.
32
More than 6 unbalance retries during the final spin – spin
(and cycle) has been aborted.
33
Oversuds detected during wash cycle and washer was not
able to resolve the condition – cycle has been aborted.
71
Generation 2 debit card cycle polling message out of
sequence.
74
Generation 2 debit card remaining balance message out of
sequence.
75
Generation 2 debit card new card balance message out of
sequence.
88
Invalid messaging state found in data acquisition
communications
MAH14 – MHN20 – MAH21
8 Motor sensed not turning during wash cycle
F
Suds lock possible or machine overload with clothing,
spinning at less than 500rpm
10 Moto sensed not turning during spin cycle
17 Door was not locked at end of the final spin
19
Water level was reached during the wash cycle, but water
level was not maintained during cycle.
1b
Slow fill, water level never reached resulting in water valve
being turned off during pause in cycle
1d
Unbalance within a speed at greater than 500rpm and less
than 675rpm during final spin cycle
2A
Motor on full power for 15 seconds during the final spin at
500rpm and less than 675rpm. Machine will spin at slower
speed.
2F Motor speed error during spin
30 Motor speed error during wash cycle
31
Spin cycle was delayed due to wash level being sensed for
more than 60 seconds at the start of the spin
32
Unbalance at less than 500 rpm during final spin. Spin cycle
was stopped.
33 Suds detected during wash cycle
34 Spinning below 85 rpm too long during spin cycle
35 Tumbling above 50 rpm too long during wash cycle
36
Motor not slowing down after 120 seconds of coasting down
after reaching 300 rpm
37 Motor running too fast during tumble cycle
39
Motor still running after 120 seconds of coasting down after
and unbalance
40 Motor running faster than 85 rpm and the door is not locked
