11. TROUBLESHOOTING
11.1 How to overcome possible failures
[B]= machines with battery
[C]= machines with cable
[BT]= battery machine with electrical drive
Possible failures affecting the whole machine
FAILURES CAUSES REMEDIES
The machine does not work
• [B]= the battery connector is
disconnected
• [B]= connect the batteries to
the machine
• [B]= the batteries are flat
• [B]= recharge the batteries
• [C]= the machine plug is
disconncted from the mains
• [C]= plug the machine
The brushes do not turn
• the brush switch is at the
position “0”
• turn the brush switch to
position “1”
• the brush lever is not pressed • press the brush lever
• [B]= the brush motor thermal
protection has tripped: the motor
has become overheated
• [B]= release the brush lever,
turn the brush switch to
position “0” (off), letting the
machine cool down for at
least 45’
• [B]= the power supply
connector or the motor thermal
protection connector are
disconnected
• [B]= connect again the
power supply connector or
the motor thermal protection
connector
• [C]= the motor power supply
connector is disconnected
• [C]= connect again the
motor power supply
connector
• [B]= the brush motor fuse has
blown
• [B]= check and remove the
causes that made the fuse
blow, then replace it
• [B]= the batteries are flat
• [B]= recharge the batteries
• the gearmotor is broken • have the gearmotor replaced
• the motor is faulty • have the motor replaced
The brush motor has trouble in
starting (in models with cable
only)
• you are working with a dry brush
on a very rough floor
• turn on the detergent
solution cock
• you are working with extensions
having an inadequate section on
the power supply cable, or the
voltage is sensibly lower than
that intended for the scrubber
(15% less)
• avoid the use of inadequate
extensions. Increase the
section of the electric wires
and find out sockets with a
higher voltage
• the motor is faulty • have the motor replaced
The machine does not wash
evenly
• the brush or abrasive disc is
worn
• replace them
The solution does not come
out
• the cock control lever is at the
position “CLOSED”
• move the lever to the position
“OPEN”
• the solution tank is empty • fill it up
• there is an obstruction in the
tube through which the solution
is pumped to the brush
• remove the clogging,
cleaning the ducts
• the tap is dirty or does not work • clean or replace the tap,
unscrewing the screw ref. 1
