buzzer will sound for 3 seconds when the “Maximum water level” is reached to indicate
that the tank is full. If you do not hear the signal, excess water will flow out from the filler.
• If the alarm is displayed during the cycle , fill the tank and proceed as shown in the
INSUFFICIENT STEAM ALARM procedure. Furthermore, check and replace the clean
water tank 10 level probe insulation.
Note: In 18 S Dynamica and 18/24 S - B - BHD models, the steriliser introduces water into the
chamber by means of the pump to generate steam until the water touches the chamber
probe 21 . If water is not sufficient during the water inlet phase, it means that there is
leakage of steam from the valves, from the chamber or from the pipes.
• In extreme conditions, when a SPECIAL cycle is run with three fractioned vacuum pulses
and with a very heavy porous load, the expected minimum level may not be sufficient.
Reduce the load or use two vacuum pulses only.
Note: Steam is generated in 6 S Dynamica by introducing water in the chamber using the
pump and measuring the required amount by means of the volumetric counter. If there
are no leakages of water from underneath the steriliser, check correct operation of the
volumetric counter and replace it, if required.
Chamber level alarm
This alarm indicates that the time required to fill chamber 09 with the required amount of
water has elapsed.
In 18 S Dynamica and 18/24 S - B - BHD models this alarm is displayed when chamber probe
21 does not detect water in the chamber. In 6 S Dynamica the alarm appears when the
volumetric counter does not detect the required amount of water before the timeout.
• When using 18 S Dynamica and 18/24 S - B - BHD, check inclination of the steriliser (see
USE AND MAINTENANCE MANUAL, chapter INSTALLATION).
• If the problem persists, check:
- that the
water inlet pump 35 and the solenoid valve EV1 are pumping water into
chamber 09 ;
- if solenoid valve EV1 winding has blown;
- the water inlet pump 35 ;
- the water filter;
-
fuse F1 on the power board 34 .
If none of these causes are found, check chamber probe 21 which is probably not
detecting the level and the probe electric connection.
To check correct operation probe:
- open
door 16 and remove the entire contents of chamber 09 ;
- remove tray support 08 ;
- remove coil grid 19 by loosening the corresponding screw;
- reassemble back to front, i.e. by turning the grid and seal horizontally;
- switch the steriliser on in STAND-BY mode;
- run Chamber load test from the Technician Menu (option 15).
The probe could be dirty or the power cable could be interrupted. Furthermore, check
level probe grounding.
