36. (00100100) Water Leak Fault
The Motor Control Module has needed to top up the water level more than 4 times during
agitate. This is excessive, as normally only one or two top ups are required to replace the
air that has escaped from a full load during agitate. The most likely cause is that the
machine is siphoning. The other alternative is that the machine has developed a leak.
Primary Source: Pump System.
Action 1) Check the height of the drain hose outlet. Minimum 33.46in /
850mm, maximum 47.24in / 1200mm.
2) Check that the hose guide is fitted and check that the hose does
not protrude more than .78in / 20mm beyond the guide.
Secondary Source: Mechanical.
Action: 1) Check the pressure tube connections on the outer basket and
Motor Control Module.
2) Check that the drive shaft seal and the pump housing seal have
not developed a leak.
Tertiary Source: Motor Control Module.
Action: Replace Motor Control Module.
37. (00100101) Pump Blocked Error (No change in the water level)
While draining, the water level reading from the pressure sensor has not changed for over 3
minutes. There are four likely reasons for this fault.
1) The drain hose or the pressure switch hose has been squashed or kinked and the
pump out rate has been dramatically reduced.
2) The pump is partially or fully blocked.
3) The pump is not operating due to Motor Control Module, wiring or pump failure. This
fault could also appear if the machine is pumping to an unusually high head of drain
hose or into an extended length of drain hose.
4) A diverter valve fault or blockage, water level is not altering as the diverter is stuck in
the recirculation mode, giving the module the appearance the pump is not lowering
the water level.
Primary Source: Pump System.
Action: 1) Check that the drain hose has not been kinked.
2) Check the length of the drain hose and try to reduce the length if
excessively long. A 39.36in / 1 metre extension hose of the same
diameter fitted to the existing drain hose is the maximum allowable
length.
3) Check for open circuit windings in the pump. (Note: Pumps are
fitted with a thermal cut-out, which will reset on cooling.)
4) If the basket is empty of water, remove the pump from the pump
housing and check that it is not blocked. Also check the drain
hose is not blocked.
5) If the basket contains water, then service the pump from the top of
the machine by removing the top deck and inner basket. Bail out
the water, remove the pump cap and hood and clear the
restriction.
Secondary Source: Wiring.
Action: 1) Check the pump harness is connected correctly to the pump.
2) Check continuity of the pump harness.
Tertiary Source: Motor Control Module module.
Action: Activate the pump by operating the machine in spin mode. Check the
pump is rotating. If it is not operating, and Primary and Secondary
checks have been performed, then replace the Motor Control Module.
