Error code 27, LEVEL OFFSET
This error code is generated by the CPU board. The error code arises if the
level system indicates a level at the start of the wash program (when the
drum should be empty) that exceeds what the program unit can compen-
sate for automatically. This can be caused by blocked drain, blocked level
hose, a drop of water in the level hose, leaking level system, defective level
control, etc.

not contain any water.
