2. Check that there are no clothes or other foreign objects preventing
the clutch from re-engaging, and that there aren’t any defects with
the clutch mechanism.
3. Check that the pressure tube has not come off and that it is not
kinked.

(00111001) Brown Out During Display EEPROM Write Fault
The Display has requested the Motor Control Module to perform an EEPROM write. Prior
to writing, the Motor Control Module has tested the 15 Volt supply and found that it is below
the safety level for writing EEPROM and has reported this to the Display. This may be due
to transients at the time of writing or due to a faulty Motor Control Module.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
60.
(00111100) Motor Control Memory Check Fault
On power up, the Motor Control Module has checked its memory against a known
Reference and found differences.
Primary Source:
Motor Control Module Module.
Action:
Replace Motor Control Module.
68.
(01000100) Pressure Transducer Error – Count Too High
The pressure transducer has measured a water level far above what the machine should
physically be able to measure. This suggests that the pressure sensor has been
disconnected from the Motor Control Module, damaged or not actually placed on the PCB.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
69 (01000101)
Pressure Transducer Error – Zero Too Low
The pressure sensor is zeroed in the factory, but to compensate for zero-drift during the life
of a product the zero is adjusted at the end of each cycle if required. The product only
zeros the pressure sensor once, on first power up when the Pressure Transducer EEPROM
locations are out of the expected zero bounds. During the zeroing process if the zero value
is below what is expected then fault code 69 is flagged.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
70 (01000110) Pressure Transducer Error – Zero Too Low
Similar to fault code 69, however, it protects against a zero, which is too high and could
cause flooding.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
72.
(01001000) Pressure Transducer Error – Maximum Positive Drift
Over the life of a product it is expected that the pressure transducer characteristics will drift
slightly. To compensate for this the zero is re-calibrated at the end of every cycle. If this
zero is significantly different to the original factory programmed zero the fault code 72 is
flagged.
Primary Source:
Motor Control Module.
Action:
Replace Motor Control Module.
