10.1 Troubleshooting: Solutions / Remedies
01- tPt
Repeat the sterilizing process or contact the after-sales service center.
02- rEt
Wait until the power supply returns. Check the socket and replace it if necessary.
Eliminate any reductions / multiple sockets to which the machine may have been
connected. Keep electronic machines well away from the appliance as they may create
disturbance (e.g. ultrasound equipment, microwaves, cellular telephones or other
equipment that emit radio frequencies). Do not touch the machine for 3 minutes wih
the switch on.
Once the 3 minutes have elapsed, the machine will make a double acoustic signal.
Leave the main switch on. Make sure that the pressure gauge needle is on the “0” mark
(zero). Open the door and keep the “DEDUCTION” key depressed for at least 5
seconds, then release it. The machine will reset automatically now to begin a new
sterilizing cycle.

Wait until the message stops flashing and then open the door.
04- SLP
Press any key to re-activate the functions if the machine must be used again, otherwise
switch off the machine.

correct way. NOTE: this operation must only be carried out by After-sales Service
staff.
11- HIt
Temperature too high:
- Check and calibrate temperature probe type PT 100: NOTE: this operation must only

and replace the probe with a genuine spare if necessary.
NOTE: both these operations must only be carried out by After-sales Service staff.
