Is the washing machine installed
at an angle?
Adjust the height of washing
machine to be kept horizontally.

Is the laundry mixed?
The few items of clothing will clump together
and their weight will be in one area of the drum,
throwing the weight off during spin mode.
So add some laundry to overcome UE error.
And rearrange load to allow proper spinning.
Try rearranging the laundry in drum
Or the laundry is separated by size, type, and color.

m maximum.
- Your washer will not be able to drain out
water adequately, if the standpipe exceeds 1.0 m.
In this case, water may flow back into the washer.
