13.7 ELIMINATION OF SMALL TROUBLE
In some cases it is possible to eliminate possible small trouble with the help of the following instructions.
1. If the program doesn’t start, verify that:
• The instrument washer is plugged to the power.
• Power supply has not been interrupted.
• Water faucets are open.
• The instrument washer’s door is correctly closed.
2. If water is stagnant in the device’s tank, verify that:
• The outlet pipe is not bended.
• The discharge siphon is not clogged.
• The instrument washer’s filters are not clogged.
3. If the general loading elements do not get cleaned, verify that:
• Detergent has been inserted, and in the proper quantity.
• Instruments have been correctly placed.
• The selected program is suitable to the type and quantity of dirt on the instruments.
• All the filters are clean, and they are correctly inserted in their places.
• The water outlet holes in the sprayers are not clogged.
• Objects haven’t blocked the sprayers rotating movement.
4. In case the loaded elements don’t dry or are opaque, verify that:
• Conditions of the absolute drying filter: hour of functioning viewable as device parameter (the hours of
default functioning are established in reference to normal usage conditions; environments with higher
quantity of dirt reduce the residual life of the drying filter)
• Neutralizer is present in the appropriate container and its distribution is correctly set.
• The detergent in use is of good quality and has not lost its properties (for example because of wrong preservation,
with its box open).
5. In case the processed elements show strips, stains or similar signs, verify that:
• The dosage quantity of the neutralizer is not excessive.
6. In case there are rust traces in the tank:
• The tank is made of steel which is corrosion resistant, therefore possible rust traces are usually due to external
elements (traces of rust coming from water pipes, etc). Specific products are available to eliminate such traces
• Verify that the right dosage of detergent is being used. Some detergents can be more corrosive than others.
7. In case the optional printer doesn’t work:
• Verify that thermal paper is present and suitable for usage with the device.
• Verify that the device is correctly connected (both to power and data connection).
8. If the sliding door doesn't close or doesn't open:
• Check that the detergent compartment and bottom door are closed correctly.
• Check that the technical safety key (for manual operation of the loading door), if fitted, is correctly positioned:
turn it to “0”.
9. If the display (loading or unloading side) remains off or unresponsive even with the switch correctly set
ON:
• Wait a few seconds, the display PCB might be initialising.
• If the display still does not come on after a few moments (screen completely dark): do not touch the display and
switch the device off using the main switch. Wait at least 10 seconds after switching off before switching back on
again.
• If the display does not reset correctly and remains "dead": contact the after-sales service, as no procedures are
possible on the machine if the interface is not active and correctly operational.
If the functioning trouble is still persisting even after following of the above mentioned instructions, it will be
necessary to ask the intervention of the closest authorized technical assistance centre.
