Care
For directions on the care of this fitting, refer to the
accompanying Care Instructions.
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, see Maintenance
Replacing the servo motor
No flushing after pressing the
button
• Water supply interrupted - Open isolating valve in cistern
• Radio transmitter not registered - Register radio transmitter, see
Registering a radio transmitter
• Electronics defective (indicator lamp
does not flash when button is pressed)
- Replace electronics, see Maintenance
Replacing the wall plate with electronics
• Servo motor defective (no rotation) - Replace servo motor, see Maintenance
Replacing the 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, see Maintenance
Replacing the transformer
• Battery in radio transmitter discharged - Replace battery, see Replacing the
battery, instruction: 96.485.XXX
• Actuation plate is not suitable - Replace actuation plate
Water flowing continuously • Waste valve not closing - Adjust servo motor position, see
Calibrating the servo motor, or waste
valve defective (repair, replace), see
Cistern instructions
Undesired flushing • Adjacent radio transmitter unintentionally
registered
- Delete all radio transmitters, see Deleting
a radio transmitter, and re-register the
correct radio transmitters, see
Registering a radio transmitter
Flow volume too low • Flow volume set too low - Adjust flow volume, see Setting the flow
volume
• Outlet valve does not lift fully out - Adjust servo motor position, see
Calibrating the servo motor
• Servo motor defective (incomplete
rotation)
- Replace servo motor, see Maintenance
Replacing the servo motor
• Residual flow rate too high - Push residual flow slider downwards, see
Setting the flow volume for manual
actuation
• Flow rate in cistern too low - Turn float of filler valve further upwards
Flow volume too high • Flow volume set too high - Adjust flow volume, see Setting the flow
volume
