246. Wash Boost / Bleach Valve Fault
The Motor Controller module has detected that the Bleach valve (red clip) is faulty. It determines this by
measuring voltages from the valve diagnostic circuit. The most likely cause is that the valve harness has
not been connected correctly or the valve is open circuit.

247. Smart pump Flapper Fault

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.
Motor Control Module.
Replace Motor Control Module.
Wiring.
Check the valve harness is correctly fastened to the valve or the pins are not
bent backwards.
Bleach Valve.
Check the valve coil is not faulty (i.e. not open circuit – See 1.8).
Motor Controller module.
Replace the Motor Controller module.
Flapper valve.
Check for free movement of the flapper valve (replace if broken or damaged).
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.
Cap not tight, warped, damaged (worn).
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.
