Electrolux EWM1100 - Error E52 no Signal from Motor Generator; E52: no Signal from the Motor Tachometric Generator (Second Part)

2007-10 SOI/DT-mdm FCPD-dp Quality-fz 38/59 599 70 32-47
YES
YES
E52: No signal from the motor tachometric generator (second part)
E52
Cycle blocked after 5 attempts during the cycle or immediately if detected at the start or during
diagnostics.
E52
Tests to be performed:
To check the wiring, measure (Ω)
across the following terminals of the
circuit board connector (fig.4) and
compare with the correct values
(see page 39: step 4 – motor
parameters)
- across J7-2 and J7-5, the value must
be as in 4 - B (Stator)
- across J7-1 and J7-5, if present, the
value must be as in step 4 - D (stator ½
range).
- across J7-2 and J7-4, the value
must be as in step 4-C (rotor).
Are these values correct?
Replace the circuit board and restart
the diagnostic cycle to check for
further alarm conditions.
Check the motor
as described on
page 39.
Is the motor OK?
The motor does not rotate at all.
NO
Replace the motor
and restart the
diagnostic cycle to
check for further
alarm conditions.
NO
Check/replace
the wiring 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
