RECOMMENDATIONS FOR A CORRECT PREVENTIVE MAINTENANCE
The aim of this schedule is to prevent as far as possible equipment from breaking down, through the periodical check-up
and replacement of components subject to fair wear and tear, thus reducing service calls and relevant cost in working hours.
This schedule is based on the suppliers recommendations along with previous service history on equipment currently out in
the field.
It is designed to assist in extending the operational life of the equipment.
A. Pre delivery inspection:
We test all machines before shipping using water. Therefore we consider our machines ready to installation.
Anyway we suggest to carry out a Pre Delivery Inspection on all machines before deliver them to final customer. PDI can
detect inconveniences which may occur during transportation or a long storage. For instance:
- screws and nuts which fit the body-work may become loose;
- flowmeter may be block by dust especially after long storage;
- screws which fit the power supply wires may become loose.
B. 2 or 3 weeks after installation:
Parts to be checked or adjusted:
1. the grinder/s settings
2. the dose settings
3. if daily cleaning of group and milk frother is carried out by the operator.
C. At 4 months’ intervals:
Parts to be changed:
1. o-rings for milk frother
2. milk silicone tube for milk frother
3. o-rings for group pistons.
Parts to be cleaned or replaced (check and decide on site):
4. o-rings for the drip tray
5. group upper piston micro screen
6. group lower piston screen
7. milk frother
8. clean the hopper by the oil of the coffee
9. clean the coffee chute by means of a dry brush
Parts to be checked or adjusted:
10. grinder setting (coarseness of the coffee powder)
11. air adjustment for milk frother
12. coffee silicone tube
13. pump pressure should be 8-9 bars, check after had closed the coffee flow valve on upper piston
14. coffee boiler expansion valve should leak at 13 bars after a few coffee deliveries
15. front door switch
16. grounds beans tray switch
17. heating element of the brewing chamber (PTC), if it's not working check the fuse next to the group
18. check the gasket underneath the sweeper
Check the functioning of the machine with the customer:
19. dose settings (setting of milk frother, steam boiler pressure…)
20. that the double coffee spout delivers consistent quantity of coffee in the cup, if not replace it
21. check how many times the group cleaning procedure has been carried out
22. check how many times the milk frother cleaning procedure has been carried out.
