36. (00100100) Water Leak Fault
The Motor Controller 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 min 33 1/2" (850mm)max 47"(1200mm.)
2) Check hose guide is fitted and check hose does not protrude more than 3/4" (20mm) beyond
the guide.
Secondary Source - Mechanical.
Action
1) Check pressure tube connection on outer tub and Motor Controller Module.
2) Check that the drive shaft seal and the pump housing seal have not developed a leak, by
looking through the front inspection cover.
Tertiary Source - Motor Controller Module.
Action - Replace Motor Controller Module.
37. (00100101) Pump Blocked Error
While draining, the water level reading from the pressure sensor has not changed for over 30
seconds. There are three likely reasons for this fault. One is that the drain hose has been
squashed or kinked and the pump out rate has been dramatically reduced. The second possibility
is that the pump is partially or fully blocked. The third is that the pump is not operating due to
Motor Controller 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.
Primary Source - Pump System.
Action
1) Check that the drain hose has not been kinked.
2) Check length of drain hose and try to reduce length if excessively long. A 39"(1 metre)
extension hose of the same diameter fitted to the existing drain hose is the maximum
allowable length.
3) If basket empty of water, remove the basket from the top and check that it is not blocked.
Also check the hose is not blocked.
4) If basket contains water, attempt to flick start the pump fan while draining to clear water
before servicing as in 3. If unsuccessful then service pump from the top of the machine by
removing the top deck and inner basket.
5) Check for open circuit windings in the pump. (Note: Pumps are fitted with a thermal cutout,
which will reset on cooling).
Secondary Source - Wiring.
Action
1) Check Pump Harness is connected correctly to pump.
2) Check continuity of pump harness.
