37. (00100101) Phase 1 to 6 - 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
Controller module, wiring or pump failure.
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:
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 inch (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 Tub 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 Tub contains water, then service the pump from the top of the machine
by removing the top deck and Basket. Bail out the water, remove the pump
cap and hood and clear the restriction.
Secondary Source:
Action:
1) Check the pump harness is connected correctly to the pump.
2) Check continuity of the pump harness.
Tertiary Source:
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 Controller module.
Note: Consider fitting Pump Hood Kit (WM013). If (5kg) 11lb Smartdrive fit splash
guard to pump.
Quaternary Source:
Action:
Check the diverter valve, see fault code 51
38. (00100110) Phase 1 to 6 - Pressure Sensor Fault
The Motor Controller 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:
Action:
Check that the pressure tube is intact and has not been cut.
Secondary Source:
Pump System.
Wiring.
Motor Controller module.
Diverter Valve failure (Phase 5 and 6 Eco's )
Mechanical.
Motor Controller module. (Display Module Phase 1)
