SCC
Edition 10-2008a
Controling the SC pump and solenoid valves before starting the cleanjet process:
If the Cleanjet Start key is pressed the unit will check rst for the proper function of the SC pump and
the solenoid valves.
The SC pump is operated shortly until the level electrode shows low water.
In case of failure “Servcie 10” is displayed and Cleanjet can not be started.
Y1 lling solenoid valve is started, function checked by CDS sensor
In case of failure “Low Water” will be indicated
Y3 moistening solenoid valve is started, function checked by CDS sensor
In case of failure Service 41
Y4 care solenoid valve is started, function checked by CDS sensor
In case of failure Service 42
All solenoid valves are switched off, CDS shall not send any pulses;
In case of failure Service 43
New Service Error codes
Service 40
Care pump faulty or does not ll enough care solution into steam generator;
- After lling of the care solution into the steam generator the CDS sensor sends too many pulses
until the level electrode recognises water.
- Cleanjet nishes without care phase;
- Reset by successfull completion of Cleanjet process;
Service 41
- Solenoid valve Y3 defective or moistening nozzle blocked; CDS does not send any pulses;
- Reset error by successfull CDS measuring during next Cleanjet start;
Service 42
- Solenoid Y4 Care defective or hose to care container vlocked or kinked; CDS does not send any pulses;
- Reset error by successfull CDS measuring during next Cleanjet start;
Service 43
- CDS sensor sends always pulses; Solenoid Y1, Y3 or Y4 is passing water
- Reset error by successfull CDS measuring during next Cleanjet start (Self test)
Service 44
- No temperature raise during recognised by B5 during steaming time while being in Cleanjet phase
- Reset error by successfull B5 tempoerature measuring during next Cleanjet;
Service 110
- Malfunction of SC pump during the time when Care solution was inside the steam generator,
- Reset error by successfull completing a cleanjet abort cycle;
Service 120
- After operating care pump M12 ( lling care solution into steam generator) and topping up with water (Y1)
the level electrode does not recognise water;
- Y1 or level electrode defective;
- Display only after twice starting lling solenoid Y1 yet no water is detected;
- Reset error by successfull completing a cleanjet abort cycle;
