Fisher and Paykel GWL11 washer not going into rinse cycle, getting error code 37
Pump should read
110V AC pump 60Hz 7Ohms +/- 8% @ 20oC
230V AC pump 50Hz 33Ohms +/- 8% @ 20oC
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 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 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 bowl 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 bowl contains water, then service the pump from the top of
the machine by removing the top deck and inner bowl. 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.
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.
