PROBLeM:
The detergent flow does not stop
CAUSE
SOLUTION
The solenoid valve is faulty.
Replace the solenoid valve.
PROBLeM:
The suction motor does not start
CAUSE
SOLUTION
The suction button LED is off.
Press the suction button.
There is no power to the suction motor or the motor is faulty.
Check that the motor power connector is correctly connected
to the main wiring; if it is correctly connected, have the motor
replaced
MOSFET temperature > 150°C
Stop the machine, leave to cool down for 45’.
PROBLeM:
The squeegee does not clean or suction is ineffective
CAUSE
SOLUTION
The edge of the rubber blades in contact with the floor is worn. Replace the rubber blade.
The squeegee or hose is blocked or damaged.
Unblock and repair the damage.
The float switch has tripped (dirty water drum), is clogged by
dirt or broken.
Empty the dirty water drum or reset the float switch.
The suction hose is blocked.
Unblock the hose.
The suction hose is not connected to the squeegee or is
damaged.
Connect or repair the hose.
There is no power to the suction motor or the motor is faulty.
Check that the motor power connector is correctly connected
to the main wiring and that the fuse is not blown; in the
second case have the motor replaced.
PROBLeM:
The batteries do not provide the normal work time
CAUSE
SOLUTION
The battery poles and charging terminals are dirty and oxidised. Clean and grease the poles and terminals, charge the batteries.
The electrolyte level is low.
Top up all the elements with distilled water as described in the
instructions.
The battery charger does not work or is unsuitable.
See battery charger instructions.
There are considerable differences in density between the
various elements of the battery.
Replace the damaged battery.
PROBLeM:
The battery discharges too fast during use, even though it has been charged correctly and when
tested with a hydrometer at the end of recharging, it turned out to be uniformly charged
CAUSE
SOLUTION
The battery is new and does not deliver 100% of its expected
capacity.
The battery must be “run-in” by performing 20-30 charges and
discharges to obtain maximum performance.
The machine is being used at maximum capacity for continuous
periods and the working time is not sufficient.
If possible, use batteries with a higher capacity or replace the
batteries with others charged previously.
The electrolyte has evaporated and does not cover the plates
completely.
Top up all elements with distilled water until the plates are
covered then charge the battery.
