Operational errors / Malfunctions
7.1
What to do if the autoclave malfunctions
________________________________
If the autoclave does not seem to be working properly (e.g. poor drying, warnings, or error reports) then follow
these instructions in order to exclude possible operational errors.
Following these instructions continue to work with the autoclave. If the malfunction occurs repeatedly then
contact our dealer, and authorised MELAG customer service or contact MELAG directly. You should describe
the problem precisely and include the works number of your appliance.
7.2
Malfunctions without display messages
_________________________________
7.2.1 No
display _______________________________________________________________________
After switching on the autoclave, the display should show the initial setting (see Section: 4.1.2).
If there is no display: Check:
1. Is the cable plugged into the mains?
2. Is the mains supply O.K.? (if necessary check with another appliance).
3. Exchange the two power fuses (page 4, Fig. 1, Pos.9) under the switch as follows: Disconnect the
power cable and remove the screw cap over the fuses using a screwdriver or a coin. Exchange the
fuses (two reserve fuses are on the inside of the door lining) then replace the screw cap and
reconnect the autoclave to the power supply. If there is still no display when the autoclave is switched
on, or if the display blacks out repeatedly, please inform your specialist dealer. If you exchange the
fuses, order two new spare fuses through your dealer (MELAG-Art. No. 57590).
7.2.2 Excessive
water
consumption ______________________________________________________
The consumption of distilled or demineralised water will vary depending on the program and the load in the
autoclave. If much more water is consumed than the amount specified in the Annex (see Section 9.2), then
you should:
1. Check that the autoclave has been set up correctly, and is higher at the front, so that condensate
can flow out at the back (see Section 0).
2. Check that the condensate outflow is not blocked by dropped, instruments, filter paper, etc. on the
floor of the pressure chamber.
3. If neither of these measures help to reduce water consumption, please inform your specialist dealer.
7.2.3 Poor
drying ______________________________________________________________________
Good drying depends only on the correct operation of the autoclave, but also on the way the autoclave is
loaded. If drying is not satisfactory:
1. Check that the autoclave has been set up correctly, and is higher at the front, so that condensate
can flow out at the back.
2. Check that the condensate outflow is not blocked by dropped, instruments, filter paper, etc. on the
floor of the pressure chamber.
3. Check that the maximum load has not been exceeded (particularly for textiles), that the autoclave
has been loaded properly (no direct contact with the walls of the pressure chamber), and that the
appropriate tray-rack assembly has been used (see Section: 4.2).
4. Activate automatic pre-heating (see Section: 6.5).
5. Start with "Additional heating" (see Section: 6.2).
6. If none of these measures help to reduce water consumption, please inform your specialist dealer.
