LCD A 250 Indication Alarm description Effect / Symptom
PV1 TIMEOUT
1st vacuum pulse not reached
within timeout.
During the 1st vacuum pulse, the 0.80 bar value is
not reached within timeout time
Possible causes / Checks Solution
Problem with autoclave
loading – check load.
Check quantity and arrangement of load inside chamber.
Observe the indications provided in the User Manual.
Problem with chamber
drain lter – check
component.
Check and clean chamber lter.
Observe the indications provided in the User Manual.
Problem with vacuum pump
activation – check pump.
Conrm vacuum pump start-up.
To perform this check, it might be a good idea to activate the vacuum pump from menu
SERVICE/COMPONENT TEST/OTHER COMPONENTS – SOLENOID VALVES SQ
14, that lets you detect air suction from the chamber.
Measure pump power supply voltage.
Change vacuum pump.
Problem with vacuum
pump performance – check
device.
Check vacuum pump tube connections.
Check vacuum pump diaphragms.
Check vacuum pump shutters.
Vacuum pump maintenance.
Problem with solenoid valve
activation – check solenoid
valves.
Check for proper activation and opening of EV3 – EV4.
To perform this check, it might be a good idea to check for EV3 –EV4 opening activate
from menu SERVICE/COMPONENT TEST/OTHER COMPONENTS – SOLENOID
VALVES – SQ 15, that lets you detect air suction from the chamber.

Problem with water
injection pump of steam
generator – check device.
Problem with steam
generator clogging – check
device.
Check feed tank lter and water injection pump inlet lter.
Check for proper activation of water pump and check that EV6 opens.
To perform this check, it might be a good idea to activate vacuum pump and EV6 from
menu SERVICE/COMPONENT TEST/OTHER COMPONENTS – SQ 17, that lets you
detect water owing through the generator and into the chamber.
Identify leaks on tubes connecting water pump and generator.
Change vibration pump.
Steam generator maintenance – see datasheet ST01.
