thermostat at the front of the machine.
If the problem persists contact the
assistance service.
E19
Excessive pressure
during sterilisation in
emergency cycles.
Fault during the
sterilization phase.
Allow the steriliser to cool and then
perform a sterilisation cycle with a small
load in the boiler (just one tray). If the
problem persists contact the assistance
service.
E21
Excessive pressure
during sterilisation.
Fault during the
sterilization phase.
Allow the steriliser to cool and then
perform a sterilisation cycle with a small
load in the boiler (just one tray). If the
problem persists contact the assistance
service.
E22
Insufficient pressure
during sterilisation.
Sterilisation phase
fault, or overload, or
steam loss.
Allow the steriliser to cool and then
perform a sterilisation cycle with a small
load in the boiler (just one tray). Make sure
no water leaks or drips on the front. If the

service.
E24
Insufficient
temperature during
sterilisation.
Fault during the
sterilisation phase,
probably due to a leak
during a vacuum
phase.
Allow the steriliser to cool and then
perform a vacuum test. If this is successful,
perform a sterilisation cycle with a small
