Check that there is no excessive wear to the pump housing port caused by
foreign objects. Replace pump if necessary.

SmartPump Timeout Fault (No change in water level)
While draining, the water level reading from the pressure sensor has not changed for 3 minutes. This
fault will generally be caused by a problem with the pump system, from either a blockage or restriction in
the pump system. This will also flag if the machine is By-Passing.
Primary Source:
Pump System.
Action:
1. Check that the drain hose has not been kinked.
2.
Check the length of the drain hose. A 1-metre extension hose of the same
diameter fitted to the existing drain hose is the maximum allowable length.
3.
Check that the machine is not pumping to a head that exceeds the pump’s
limits (2.4 meters is maximum head height).
4.
Remove the inner bowl and check that the pump hood hasn’t been fitted
around the wrong way.
5.
Check for lint streaming from the pump hood that may be blocking the cap
inlet.
6.
Remove the pump hood and cap. Check for lint, grit and debris.
7.
Check for free movement of the flapper and that the impeller hasn’t come
off the rotor.
8.
Check for free movement of the flapper (replace if broken).
9.
Check for lint and foreign objects in the ports of the pump housing.
Secondary Source:
Motor Control Module.
Action:
Replace Motor Control Module.

SmartPump Loss of Sync
This fault is normally as a result of the pump not starting and is usually caused by an object that has got
into the pump, and is either under or on top of the impeller, which is causing the motor to stall when
trying to start.
Primary Source:
Pump stator winding open circuit.
Action:
Check the resistance of the pump stator. Resistance per Phase: 8.1Ω +/-
10% (16.2Ω +/- 10% phase to phase).
Secondary Source:
Pump System.
Action:
1. Check that the drain hose has not been kinked.
2.
Check the length of the drain hose. A 1 metre extension hose of
the same diameter fitted to the existing drain hose is the maximum
allowable length.
3.
Check that the machine is not pumping to a head that exceeds the pump’s
limits (2.4 meters is maximum head height).
4.
Remove the inner bowl and check that the pump hood hasn’t been fitted
around the wrong way.
5.
Check for lint streaming from the pump hood that may be blocking the cap
inlet.
6.
Remove the pump hood and cap. Check for lint, grit and debris.
7.
Check for free movement of the flapper and that the impeller hasn’t come
off the rotor.
8.
Check for free movement of the flapper (replace if broken).
9.
Check for lint and foreign objects in the ports of the pump housing.

Bridge Test Failure
The Motor Control Module has tested the motor bridge electronics and sensed current when there
should not have been any.
