E32: Electronic Pressure Sensor calibration problems

E32
Water inlet valve defective, Pressure Sensor defective, Drain pump defective,
Drain pipe blocked, wiring or Main Control Board
Checks to perform:
Is the air tube connected properly (check also for kinking
and leaking)? (Disconnect the tubes and blow into them to
make sure the system is unobstructed) (See Fig. 1)
Is the frequency of Pressure Sensor between 45 Hz to 45.5
Hz? (Measure it on the pressure sensor wiring connector at
Main Control Board when machine is owered with empty
tub (No water)) (See Fig. 2)
Is the resistance measurement of the
Solenoid Valve approximately 1375Ω
± 10% (Measure it directly on the
connector on the Main Control Board
side between terminals J20-1 & J20-3,
J18-1& J18-3 and J18-4 & J18-6
(See Fig. 3).
Is the drain pipe positioned correctly and not causing
the siphon effect? (See Fig. 5)
Is the resistance measurement of
the Drain pump approximately 12Ω
to 17Ω? (Measure it directly on
the connector on the Main Control
Board side between terminals J15-
3 & J15-4). (See Fig. 6)
Replace the Main Control Board and repeat the Diagnostic
Cycle to check for any further alarms.
