The brush doesn’t rotate
• the brush button LED is off
• press the brush button
• the brush lever has not been
pressed
• press the brush lever
• [B] [C] the brush motor thermal
cutout has tripped; the motor
has overheated
• [B] [C] release the brush
lever, press the brush button
(LED off), leave the machine
to cool down for at least 45'

>30 A for 1 second
•[B]= stop the machine and
check the motor
• the power supply or motor
thermal cutout connectors are
disconnected
• reconnect the power supply
or motor thermal cutout
connectors
• [C]= fuse blown
• [B] [C]= replace fuse
• [B]= the batteries are flat
• [B]= charge the batteries
• the reduction unit is faulty • have the reduction unit
replaced
• the motor is faulty • have the motor replaced
The brush motor has trouble in
starting (cable models only)
• you are working with a dry brush
on a very rough floor
• open the detergent tap
• 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)
• avoid the use of
inappropriate extensions.
Increase the section of the
electric wires and locate
sockets with a higher voltage
• the motor is faulty • have the motor replaced
The machine does not clean
evenly
• the brush or disk is worn • replace
