Fisher Paykel model GWL11 washer will not drain water after…

Hello and thank you for your question, I will be assisiting you with your inquiry today,

Your fault code is as follows and relates to a blockage or faulty water pump:

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. 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 Controller 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 Controller module.


A new pump is worth about $60, check the resistance of the water pump, if should be around 33 ohms at the pump wiring terminals. If it checks out okay, remove the pump to check for blockages,,

See if you can start the machine in the last spin cycle, the pump should run by itself for a few minutes before the machine tries to spin dry, if no pump is running and the fault code continues, there is definetaly a problem there...
