E32: Pressure Sensor Calibration Problem

E32

Pressure Sensor defective or Main Control Board defective.

Checks to perform:

 WARNING

Check that all the connectors are correctly 

inserted.

Check if air tube is connected properly without 

kinking and leaking? (Disconnect the tubes, and blow 

into them to make sure the system is unobstructed.)    

(See Fig. 1)

Y

E

S

Is the frequency of Pressure Sensor between 44.5 Hz 

and 45 Hz? (Measure it on the Pressure Sensor wiring 

connector at Main Control Board when machine is 

powered with empty tub (No water).) (See Fig. 2)

Y

E

S

Replace / Repair the air tube, and repeat the 

diagnostic cycle to check for any further errors.

Replace Pressure Sensor and repeat the 

diagnostic cycle to check for any further error.

NO

NO

Replace the Main Control Board and repeat the 

diagnostic cycle to check for any further errors.
