• In configuration (B), check that the water supply tap is open and that the mains water
pressure is higher than the minimum pressure indicated for the installed demineralisation
system.
• If the problem persists, check if solenoid valve EV7 opens correctly.
In both cases, check:
- that all connections are properly connected;
- that all pipes are in their seats and neither cracked nor twisted.
Door alarm
This indicates that door 16 is not correctly closed.
The steriliser may display this message when an attempt is made to start a cycle but the
door is not completely locked. The steriliser will not start in this condition.
• Close the door well before starting a cycle.
• If the problem persists, despite the door being locked, micro-switch M1 36A and/or
micro-switch M2 36B are not correctly pressed or faulty. Check that:
- the lock nuts on the micro-switches are tight;
- the pin is not bent, out of its seat, or loose;
- there is continuity at micro-switch contacts (use a tester);
- there are no obstructions or dirt near the micro-switch rod;
- the connection cables between the door and the steriliser are operating and
properly connected.
Note: To determine which of the two micro-switches is generating the signal, check:
- if the alarm is triggered immediately after starting the cycle, it means that the pre-closing
micro-switch is not working (micro-switch M2 36B);
- if the alarm is triggered 3 minutes after starting the cycle, it means that the door lock
micro-switch is not working (micro-switch M1 36A).
