Note: - Always carry out an earth insulation test before using the fault guide, an earth fault on a
component or damaged wiring may display fault codes not related to the component signalled, e.g.
an earth fault on the element can display A02.
If any earth faults are found on initial testing they must be rectified before using the fault code chart,
to avoid erroneous codes being displayed.
Modern components especially modules are very reliable, therefore edge connectors, contacts and
wiring should be thoroughly tested before trying components.
A01
The micro-switch in the base tray has been closed for 9 seconds to signal the alarm.
Water is leaking from components or hoses in the base of the machine.
Programme will abort and the drain pump will be energised.
A02
The module has detected movement of the turbine for 9 seconds when the inlet valve was not
energised.
The inlet valve is letting water by when the valve is closed.
The programme will be aborted and the drain pump is energised.
Note: Earth faults on the heating element and wash pump can display A02.
A03
The drain pump has been energised for 4 minutes, but the pressure switch has not switched
to the empty position (contacts 11-12).
The drain pump is fed from the wash pump; therefore an open circuit wash pump could stop
the drain pump from working.
Check continuity of the pump coil.
A jammed drain pump or blockage in the outlet hose or plumbing.
A blocked pressure chamber or pressure switch air tube.
A faulty pressure switch.
Check wiring to pump and module connections.
If all the above are OK, replace the module.
A04
The module has detected either an open or short circuit on the thermistor or its associated
wiring.
A05
Filter blocked
The machine has tried to carry out the filter cleaning cycle but has failed to clear the blockage.
Check the filter or sump is not blocked.
Check the pressure switch is not stuck in the empty position (contacts 11-12) or the
pressure chamber or air tube are either blocked, unattached or split.
Check the high pressure sensor or the connecting hose for blockages.
Check the wash pump is circulating the water.
Check the wiring to the pressure switch and high pressure sensor.
Check the edge connector blocks on the pressure switch and module card.
Check the outlet hose is not too low causing the machine to siphon.
If all the above tests are OK replace module card.
Aborts the cycle and energises the drain pump.
