and observe the washing machine’s operation
carefully.
: Check the voltages. (An error occurs when
under or over voltage is supplied.)
: Check whether a plug receptacle is used.
When the connecting wire is 1m, a momentary
low voltage may drop up to 10 V
- Main PBA fault (sometimes)
- Please check the door conditions if there is no
problem in a consumer’s power and main PBA.
