What the Service Includes
Brew unit repair is a comprehensive restoration of the coffee machine’s core component. The service covers:
- full diagnostics of the brew group and related systems
- complete disassembly of the mechanism
- deep cleaning of all parts from coffee oils, scale, hardened deposits
- replacement of worn seals, gaskets, O-rings, shower screen
- repair or replacement of piston, gears, bushings, springs
- lubrication of all moving parts with food-grade silicone
- adjustment of the puck compression mechanism
- leak testing after reassembly
- testing in various brewing programs (espresso, lungo, doppio, large cup)
- flushing the hydraulic system and boiler from old residues
In severe cases (cracked housing, destroyed gears, deformed piston), the entire brew unit is replaced with an original or high-quality compatible part. Work is always performed according to the specific machine model.
When Brew Unit Repair Is Required
Signs indicating the need for brew group repair:
- coffee is watery, weak, almost no crema
- puck comes out wet, loose, or does not form properly
- very fast jet-like flow during brewing
- water bypasses the coffee or fails to pass through the grounds
- machine displays brew unit related error codes
- brew group does not return to home position or moves jerkily
- grinding, crunching, scraping or knocking noises during operation
- inconsistent drink volume in the same program settings
- symptoms return quickly after cleaning and lubrication
- visible cracks, chips, or excessive play in the group housing
These issues usually appear after 800–2500 brewed cups (depending on water hardness, bean quality, and maintenance regularity). Timely repair often prevents the need for full replacement of this expensive component.
