(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 three likely reasons for this fault. One is that the drain hose or the
pressure switch 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 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. The fourth possibility is 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.

(00100110) Pressure Sensor Fault
The Motor Control Module has recorded a water level of empty while it is agitating. The
water level must have been greater than empty for the machine to enter the agitate mode
initially. The most likely cause of this fault is that the pressure sensor hose has been
severed or fallen off during agitate. Alternatively, the pressure sensor may be faulty.
Primary Source:
Mechanical.
Action:
Check that the pressure tube is intact and has not been cut.
Secondary Source:
Motor Control Module.
Action:
Replace the Motor Control Module if the pressure tube shows no sign
of being faulty.
39.
(00100111) Pressure Tube Fault
The probable cause of this fault is that the pressure tube has become blocked or kinked or
has fallen off completely. Alternatively, the pressure sensor may be faulty.
Primary Source:
Mechanical.
Action:
Check that the pressure tube is intact and not blocked with water or
dirt and is not kinked.
Secondary Source:
Motor Control Module.
Action:
Replace the Motor Control Module.
