Cleaner with radio remote:
-
Investigate if both ON/OFF (cleaner and remote) are non-functional.
If remote ON/OFF working, but not cleaner ON/OFF:
-
Investigate if the plastic knob reaches the ON/OFF switch on the PCB.
-
Replace the control unit (display PCB).
If cleaner ON/OFF working, but not remote ON/OFF:
-
Investigate if the LED on the remote indicates transmission. If not, change
battery and try again.
-
If still no LED indication on remote, change remote control and reprogram

Cleaner with active motor nozzle:
-
Investigate if both ON/OFF (cleaner and remote) are non-functional..
If remote ON/OFF working, but not cleaner ON/OFF:
