Fault/defect
Short acoustic signal when
the cover is closed
(mains device plugged in),
but no double beep after
5 - 8 seconds
Regularly recurring
acoustic signals
Long acoustic signal before
water flows
Long acoustic signal instead of
water flowing
Recurring short
acoustic signal (every 2 seconds)
Incorrect water temperature
No water
Too little water
Water flows constantly
No acoustic signal when
the cover is closed
(mains device plugged in)
Possible cause
