Ea1: Drum Positioning System Faulty (Top-Loaders) - Electrolux EWM25 series Service Manual

EA1: Drum positioning system faulty (top-loaders)

EA1
No signal or discontinuous signal from the sensor for more than 10 seconds during actioning
Checks to perform:
Is the belt ok? Is the pulley ok and the ferrite plate correctly
Remove the connector and measure directly on the
- closed circuit when it is in the normal part of the pulley
(fig. 18) - open circuit when it is on the plate (fig. 19).
Is the sensor ok?
Reconnect the connector on the sensor and measure
across J12-1 and J12-3 of the connector wiring: turning
the drum, the circuit must open and close. Check between
the same contacts if there is current leakage.
Start the diagnostic cycle (phase 9). If alarm EA1 appears
again, replace the circuit board and restart the diagnostic
cycle to check for further alarms.
