Care
For directions on the care of this fitting, refer to the
accompanying Care Instructions.
Cause
• Calibration incorrect
• Obstacle during calibration
• Servo motor defective
• Water supply interrupted
• Radio transmitter not registered
• Electronics defective (indicator lamp
does not flash when button is pressed)
• Servo motor defective (no rotation)
• Plug-in connector without contact or not
connected
• Radio transmitter too far away
• No voltage
• Transformer defective
• Battery in radio transmitter discharged
• Actuation plate is not suitable
• Waste valve not closing
• Adjacent radio transmitter unintentionally
registered
• 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
