249. (11111001) 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
(refer to section 4.9.11).

Secondary Source: Motor Control Module.
Action:
Poor Flapper Seal.
1. Clean any foreign objects out of the pump, concentrating especially
on the flapper and drain/re-circulating port areas.
2. Remove the flapper to ensure no foreign objects exist below and
around the flapper.
3. Check the flapper damage, especially the lip seals. If damaged,
replace.
1. Check that the hood/cap is tight. If loose and screws are difficult to
tighten, foreign objects could be in the screw boss. Remove pump
fully and inspect/ replace if in doubt.
2. Check the cap is not warped or it is not excessively worn in the
area where it contacts the flapper. Replace the cap if warped or
worn.
Damaged Pump Housing Port.
Check that there is no excessive wear to the pump housing port
caused by foreign objects. Replace pump if necessary.
Replace Motor Control Module.
Pump System.
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.
Replace Motor Control Module.
