How to resolve possible problems
[B]=
battery machines
[C]=
cable machines
Possible problems affecting the whole machine.
PROBLEM
The machine does not function
The brush doesn't rotate
The brush motor has trouble in
starting (cable models only)
The machine does not clean
evenly
No detergent is delivered
The detergent flow does not stop
TROUBLESHOOTING
CAUSE
[B]= battery connector disconnected
[B]= the batteries are flat
[B] [C]= fuse blown
[B]= temperature power board > 85°C
[B]= MOSFET temperature > 150°C
[C]= the machine is not plugged into the mains
socket
the brush button LED is off
the LED in the brush button is flashing
the brush lever has not been pressed
[B] [C] the brush motor thermal cutout has trip-
ped; the motor has overheated
[B]= MOSFET temperature > 150°C
[B]= excessive motor absorption >30 A for 1
second
the power supply or motor thermal cutout con-
nectors are disconnected
[C]= fuse blown
[B]= the batteries are flat
the reduction unit is faulty
the motor is faulty
you are working with a dry brush on a very rou-
gh floor
you are working with power cable extensions
with an inadequate section, or the voltage is
considerably lower than the rated value for the
scrubber drier as shown on the rating plate (15%
less)
the motor is faulty
the brush or disk is worn
the detergent button LED is off
detergent tank empty
• the brush motor is off
the hose delivering the detergent to the brush
is blocked
the tap is dirty or faulty
the solenoid valve is faulty
the filter is dirty
the solenoid valve is faulty

REMEDY
[B]= connect the batteries to the ma-
chine
[B]= charge the batteries.
[B] [C]= replace the fuse
[B]= stop the machine, leave to cool
down for 45'
[B]= stop the machine, leave to cool
down for 45'
[C]= plug into the mains socket
press the brush button
reduce the pressure of the microfibre on
the work surface
press the brush lever
[B] [C] release the brush lever, press the
brush button (LED off), leave the machi-
ne to cool down for at least 45'
[B]= stop the machine, leave to cool
down for 45'
[B]= stop the machine and check the
motor
reconnect the power supply or motor
thermal cutout connectors
[B] [C]= replace fuse
[B]= charge the batteries
have the reduction unit replaced
have the motor replaced
open the detergent tap
avoid the use of inappropriate exten-
sions. Increase the section of the electric
wires and locate sockets with a higher
voltage
have the motor replaced
replace
press the detergent button
fill the detergent tank
turn the motor on by operating the brush
lever
unblock and open the circuit
have the tap cleaned or replaced
replace the solenoid valve
clean the filter
replace the solenoid valve
