7       TROUBLE SHOOTING

           

7.1       TOO MUCH WATER ENTERS THE BOILER

·      The level control  (tav. 06 -  ref. 12) is faulty: replace the entire component or the mercury bulb  (tav. 06 - ref. 13).

·      The level control is not perfectly regulated : re-set by means of the regulation shaft.

·      The floater ball of the level control (tav. 06 - ref. 17)  is damaged or weighed down by calcium deposits: clean or replace.

 

7.2       THE ELEMENTS ARE ACTIVATED BUT THE BOILER DOES NOT REACH                    PRESSURE LEVEL

·      The heating elements  (tav. 06 - ref. 19) are cut out and no power is getting through : replace.

·      The  elements circuit is cutout: check the circuit and re-connect..

 

7.3       THE ELEMENTS ARE NOT ACTIVATED

·      The pressure switch (tav. 06 - ref. 7) is faulty: replace.

·      The thermal relay switch coil (tav. 07 - ref. 12) is burnt out: replace.

·      The level control (tav. 06- ref. 12) is faulty: replace the entire component  or the mercury bulb which activates the element.

·      The electric circuit of the element is cutout : check the circuit  and re-connect.

 

7.4       THE PRESSURE IN THE BOILER REACHES TOO HIGH OR TOO LOW VALUES

·      The pressure switch (tav. 06 - ref. 7) is not correctly regulated:  regulate correctly by screwing/unscrewing the regulation screw to increase/decrease pressure.

·      The pressure switch  is faulty : replace.

 

7.5       THE SAFETY VALVE OPENS

·      Pressure switch ( tav. 06 - ref. 7) set at too high values: lower the set pressure,  see 7.4

·      Pressure switch  faulty: replace.

 

7.6       THE PUMP DOES NOT START     

·      The level control (tav. 06 - ref. 12) is faulty: replace the entire component or the microswitch  (tav. 06 - ref. 13) which activates the pump.

·      The electric circuit of the pump is cutout: check and re-connect

·      The electric winding of the pump is cutout : if possible re-connect or re-wind .

·      The pump is blocked :  unblock by using a screwdriver on the rear  of the motor  on the cooling fan side. 

 

7.7       THE PUMP TURNS BUT NO WATER GOES INTO THE BOILER

·      The  water solenoid valve (tav. 08 - ref. 8) or only the coil  (tav. 09 - ref. 3) is faulty : replace the damaged part.

·      There is air in the pump fan housing : partially unscrew the cap positioned near the water outlet pipe, let out all the air and screw up again.

·      The check valve (tav. 08 - ref. 9) is blocked: some light taps on the valve can re-establish functioning,  if this is not sufficient dismantle and clean.

 

7.8       THE VENTILATOR DOES NOT START - VERY LITTLE AIR

·      The motor of the built-in vacuum is burnt out ( tav. 05 - ref. 25) : replace or re-wind.

·      Ventilation timer  (tav. 01 - ref. 6) is faulty : replace

·      Contactor coil ( tav. 07- ref. 12) is burnt out : replace

·      Ventilator switch ( tav. 01- ref. 7) is faulty : replace ( this can only happen when machine is working on manual cycle.

 

7.9       NO STEAM ISSUE

            Steaming timer (tav. 01 - ref. 4) is faulty : replace

            Steaming solenoid valve ( tav. 06 - ref. 3) or only the coil ( tav. 10-ref. 3) is damaged :           replace the defective part.

            Steam switch (tav. 01-ref. 3) is faulty : replace. ( This can only happen when machine is          working on manual cycle)

 

7.10     THE CYCLE DOES NOT START

            The microswitch ( tav. 05-ref. 33) of the start pedal is faulty : replace.

            The electric circuit of the pedal is cutout : check and re-connect.
