Thiss code indicates that the motor is not working. Please, be careful, because 3E and E3 are different codes indicating different things. The 3E fault code signals a motor stop due to an over-current. Please, note the following appropriate readings:
- Pin 1 and Pin 2 of CN9 = 3.0 ohms.
- Pin 1 and Pin 3 of CN9 = 3.0 ohms.
- Pin 2 and Pin 3 of CN9 = 3.0 ohms.
- Any 2 Pins (1, 2, 3) on Motor Connector = 3.0 ohms.
If there are no big deviations, you are in for a little guesswork.
The E3 means that the ain control board is trying to get the motor to run, but cannot detect a tachometer signal. The motor will not be running. This can happen because:
- Stuck drum. Unplug the washer and make sure there is nothing to block it.
- The hall sensor has gotten loose or faulty. It won’t let the control board recognize it as spinning. As a result, the motor will stop and there will be E3 on the display. It may read rpm partially. Then you will see SUdS on the screen.
- Check the wire harness and connections around the motor. Try unplugging each connection and plugging it back at a time. If you find any loose one, bend-lock it.
