1. The machine doesn’t starts

1) TROUBLE: Rotating the main switch “0 – I” (A) the high pressure cleaner doesn’t starts or

starts, but suddenly stops after a while.

CAUSES: 1a No electrical connection

1b No electrical supply to the electric motor or motor thermal sensor overload

intervened or burnt fuses

1c The micro-switch of bypass valve not working

(only for machine with total stop system)

1d Contactor not working (on versions three phase or P4)

REMEDIES:

1a Check the power supply voltage using a “multimeter”.

The machine power supply characteristics are indicated on the machine data plate placed on the

rear side of its chassis.

For single-phase models, the allowed voltage tolerance is +/- 5%.

For three-phase models, the allowed voltage tolerance is +/- 10%.

If the voltage is over or lower than the above mentioned tolerance, the machine electric

components may become damaged.

Pay maximum attention while checking electric component: danger of electric shocks.

1b Pay maximum attention: danger of electric shocks.

Disconnect the machine from the power supply before opening the electric enclosures, hence:

- check using a multimeter, the conductivity of the main switch contacts, rotate the switch knob to

position “I” and in case of problems, replace the switch with a new component.

To open the electric enclosures, proceed as following described:

Opening:

3. Remove the main switch knob

Remove the machine cover

5. Check the main switch contacts continuity using a

multimeter, if damaged replace it.

2. Remove the handle cover

4. O

pen the electric box cover

Pag. 9

- If the thermal sensor of the electric motor is intervened, the electric motor is disconnected and

the machine cannot work.

The thermal sensor, intervenes when the motor winding temperature is over 155°C and in order

to cool it down and allows its automatic reset, are required some minutes with the electric motor

off.

The thermal sensor is built-in into the motor winding of single phase models, while is wired into

the electric box for three-phase models or for P4 models.

The thermal sensor is a protection against overload and needed to prevent burning of the motor

windings, but has a limited life in term of number of interventions and if the machine has been

used continually under overloaded, the thermal sensor can become damaged and loose the

capacity to self reset, hence not allowing the motor to restart when decreases the winding

temperature.

In order to restore a damaged thermal sensor, is needed to replace the complete electric motor

stator.

- If the fuses of the socket or to the plug are burnt, the machine is not power supplied; replace the

fuses and check if their amperage is enough for the machine Amperage characteristics that are

readable on its data plate.

Take into consideration that a low voltage supply can cause difficulties to the motor starting and

as a consequence can makes that fuses burn.

We recommend to check the machine amperage using a clamp meter in order to be sure that the

machine working at the maximum pressure is not absorbing more Ampere than what indicated on

its data plate.

Measured

Amperage

should be less or

equal than Amperage wrote to the machine

data plate.

Check the Amperage with a A clamp meter

after switching on the machine and checking

that the machine is correctly power supplied

by the fuses.
