Fault/ cause/ remedy

Fault
Indicator lamp on front
of electronics flashing
continuously after calibration
No flushing
Water flowing continuously
Undesired flushing
Flow volume too low
Flow volume too high
Cause
• Obstacle during calibration
• Servo motor defective
• Water supply interrupted
• No voltage (indicator lamp on back of
electronics not flashing)
• Electronics defective (indicator lamp not
flashing or permanently on)
• Servo motor defective (no rotation)
• Plug-in connector without contact
• The detection zone of the sensor system
is set too low/too high
• Outlet valve not closing
• The detection zone of the sensor system
is set too high
• Flow volume set too low
• Outlet valve does not lift fully out
• Servo motor defective (incomplete
rotation)
• Residual flow rate too high
• Flow rate in cistern too low
• Flow volume set too high
Remedy
- Perform calibration again, ensuring there
is no obstacle in the adjustment range of
the servo motor, see Maintenance,
Calibrating the servo motor
- Replace servo motor, see Maintenance,
Replacing the servo motor
- Open isolating valve in cistern
- Switch on power supply or check plug-in
connection or transformer defective, see
Maintenance, Replacing the transformer
- Replace electronics, see Maintenance,
Replacing the wall plate with electronics
- Replace servo motor, see Maintenance,
Replacing the servo motor
- Attach plug-in connector
- Increase/reduce detection zone using
remote control (special
accessory 36206)
- Adjust servo motor position, see
Calibrating the servo motor, or outlet
valve defective (repair, replace, observe
replacement part), see cistern
instructions
- An opposing object is detected. Reduce
detection zone using remote control
(special accessory 36206)
- Adjust flow volume, see Setting the flow
volume
- Adjust servo motor position, see
Calibrating the servo motor
- Replace the servo motor, see
Maintenance, Replacing the servo motor
- Push residual flow slider downwards, see
Preparations, Fig. [10a]
- Turn float of filler valve further upwards,
see Preparations, Fig. [8]
- Adjust the flow volume, see Setting the
flow volume
