(Injection error, foreign material)
- The water pump terminal is not connected: rubber
band, bills, cotton, hair pins, coins have collected
inside the drain pump ASSY.
- The signals between the sub and main PBAs are not
sensed because of commuication error.
- Check the connector connections between the sub

faulty soldering.
- The Power button is pressed continually. (for more

pressed. (for more than 30 seconds).
- Deformation of an internal plastic injection part.
- A screw for assembling the sub PBA is tightened too
much.
