NO
NO
NO
YES
EA1: Drum positioning system (DSP) faulty (top-loaders)
EA1
No signal or discontinuous signal from the sensor for more than 10 seconds during actioning
of the motor to position the drum
EA1
Tests to be performed:
YES
Is the drive belt OK? Is the pulley OK? Is the ferrite plate
positioned correctly?
(fig. 20)
Replace the belt/pulley and restart
the diagnostic cycle to check for
further alarm conditions.
If there are traces of burning on the
circuit board, refer to page
59
Remove the connector and measure directly on the
sensor: - circuit closed when on the normal section of the
pulley
(fig.18)
- circuit open when on the ferrite plate
(fig.19)
.
Is the sensor efficient?
Replace the positioning sensor and
restart the diagnostic cycle to check
for further alarm conditions.
YES
Replace the connector and measure across J12-1 and
J12-3 on the wiring connector: when the drum is rotated,
the circuit should open and close. Check for leakage to
ground across the same terminals.
Is the wiring OK?
Check/replace the wiring and restart
the diagnostic cycle to check for
further alarm conditions.
Start the diagnostic cycle (
phase 9
). If alarm EA1
reappears, replace the circuit board and restart the
diagnostic cycle to check for further alarm conditions.
