Models we service and repair
Rocket Espresso is built in Milan, under its current name since 2007, before that under various predecessor brands (Echo, Cellini). The lineup spans from the compact Appartamento up to the R Nine One. We service all models.
Appartamento is the compact heat-exchanger machine, the best-seller in the Berlin prosumer market in recent years. Small, no plastic, E61, 1.8-liter tank. Fiddly to service because everything is packed in tight, but solid in itself.
Mozzafiato and Giotto are the next size up, also heat-exchanger models. Cronometro V (with shot timer) or R (with an additional PID kit). Classic E61 layout, plenty of room under the hood, a pleasant machine to work on in the workshop.
R58 / Cinquantotto is the dual-boiler variant. PID on both boilers, rotary pump (with plumbed-in water). The Cinquantotto special edition has the pre-infusion tank, which needs its own attention during service work.
R60 and R Nine One are the premium line with pressure profiling. Pressure curves are controlled via Gicar modules, and each brew group has more sensor-side components. Service on an R60 is about 30 percent more work than on an R58, because every profile curve has to be recalibrated after any intervention.
Sotto Banco is the under-counter build, similar to La Marzocco's Modbar. We work on that too.
Boxer is the commercial café machine, in two- or three-group configurations. Service characteristics are typical gastro work — on-site appointment, call-out, often emergency service.
Common problems and our fix
Appartamento, pump hums, pressure won't come through. Nine times out of ten it's the Ulka pump at the end of its life. On the Appartamento the pump is built in especially tight, so replacement takes longer than on a Giotto — about 45 minutes. Original Ulka, pressure adjustment, done. Keep running the machine with a humming pump and you risk the solenoid valve and pressure switch falling out of sync too.
Mozzafiato Cronometro V, E61 dripping after the shot. Lower brew group gasket at the end of its life. Replacement including a check of the solenoid valve takes about 75 minutes. While we're in there we always do the upper disperser gasket too, since it's rarely worth justifying as a standalone job — small part, big effect.
R58, one brew group hotter than the other. Sounds odd, the R58 only has one brew group. In practice the symptom means: water reaches the portafilter at different temperatures depending on the time of day. The cause is almost always the PID probe in the brew boiler — scaled up, drifting. Replacement and calibration done within an hour. If the problem persists after replacing the probe, we move on to the heat-exchange loop and the pump.
R60, pressure curve won't ramp up cleanly anymore. That's Gicar module territory. We check the sensors first (pressure sensor on the brew group), then the module itself. R60 control electronics are complex and need tools not every workshop has. Repair takes longer than on an R58, but it's solvable.
Appartamento, water doesn't flow back into the drip tray. Classic 3-way solenoid valve problem. The valve doesn't switch cleanly, pressure in the brew circuit doesn't release, and water stays sitting in the brew group. Disassemble the solenoid valve, clean or replace it, done.
Original parts from Milan
We source Rocket spare parts through the German distributor for Rocket Espresso. Pumps (Ulka or Fluid-O-Tech, depending on the model), solenoid valves, PID probes, control boards, Gicar modules for the R60, brew group components, heating elements.
Standard E61 parts (brew group gaskets, springs, cam pistons) we cover from the general E61 parts universe — these parts have been standardized for 60 years and often come from the same Italian suppliers anyway. What doesn't happen: aftermarket pumps or gray-market Gicar clones for an R60. Original or nothing.
On-site or workshop
Appartamento, Mozzafiato, Giotto, R58, R60 at home: Workshop. We pick up in Berlin and Brandenburg, work in Oranienburg, bring it back. Especially worthwhile for the Appartamento, since the inside is so tight — good tool setup saves half an hour.
Boxer in the café: On-site. Classic gastro service, two- or three-group machine in ongoing operation, call-out fee plus hourly rate, usually same-day.
Sotto Banco: Mixed. The tap head stays, the under-counter unit comes with us. Workshop job with an on-site lead-in.
Prices and flat rates
Service on Appartamento / Mozzafiato / Giotto: flat rate, standard parts material included. Service on R58 / R60: flat rate somewhat higher, due to dual-boiler complexity and (on the R60) Gicar calibration. Ulka pump replacement: low three-digit range. Fluid-O-Tech rotary pump (R models): mid three-digit range. Boxer on-site service: flat call-out fee plus hourly rate.

What we don't do
We don't install pressure-profiling mods on an R58 that the factory never designed for. The R58 is a great machine without profiling — if you want pressure profiles, get an R60 or an R Nine One, it'll save you frustration.
We don't repair counterfeit Rocket machines. There are imports from Russia and Turkey that look deceptively similar but have nothing to do with Milan technically. Bring one of those in and you'll get an honest heads-up and no invoice.
We don't fit third-party PID kits into a Mozzafiato Cronometro V "because someone recommended it on a forum." If you want PID, get a Cronometro R — that's exactly what it's built for.
