Error codes
The door lock control has three LEDs that show
whether the door lock operates normally or
whether an error has been detected. During
normal operation, the LEDs blink when the drum
is not turning and are off when the drum rotates.
In case of an error, the three LEDs will show the
error condition according to the table below. If an
error disappears, the error code condition
disappears. If the error is still present at the
programme end, the error is automatically
cleared after 5 minutes and the door is unlocked.
