Fault/ cause/ remedy
Fault
Cause
Remedy
Indicator lamp in electronics
flashing continuously after
calibration
• Calibration incorrect
• Obstacle during calibration
- Perform calibration again, ensuring there
is no obstacle in the adjustment range of
the servo motor, see Calibrating the
servo motor
• Servo motor defective
- Replace servo motor
No flushing after pressing the
button
• Water supply interrupted
- Open isolating valve in cistern
• Radio transmitter not registered
- Register radio transmitter
• Electronics defective (indicator lamp
does not flash when button is pressed)
- Replace electronics
• Servo motor defective (no rotation)
- Replace servo motor
• Plug-in connector without contact or not
connected
- Attach plug-in connector
• Radio transmitter too far away
- Install radio transmitter closer to cistern
• No voltage
- Switch on voltage supply
• Transformer defective
- Replace transformer
• Battery in radio transmitter discharged
- Replace battery, see Replacing the
battery, Technical product instruction:
96.485.XXX
• Actuation plate is not suitable
- Replace actuation plate
Water flowing continuously
• Waste valve not closing
- Calibrate servo motor
- Waste valve defective (repair, replace),
see Cistern instructions
Undesired flushing
• Adjacent radio transmitter unintentionally
registered
- Delete all radio transmitters and re-
register the correct radio transmitters
Flow volume too low
• Flow volume set too low
- Adjust flow volume
• Outlet valve does not lift fully out
- Calibrate servo motor
• Servo motor defective (incomplete
rotation)
- Replace servo motor
