Rocket Espresso RE Doppia — PSSR examination & servicing
RE Doppia machines are used in specialty cafés, espresso bars and roastery sites nationwide. The engineer carries out the statutory PSSR examination, the front-end service and the water treatment on this model — a standalone examination is £295 + VAT, or £500 + VAT with the service included.
Quick answer
Does a Rocket Espresso RE Doppia need a PSSR examination?
Yes, if it operates in a workplace. It carries a single steam boiler with its own protective devices, which is the pressure system in scope. Steam is a relevant fluid under PSSR 2000 and steam systems are covered at any pressure and any volume, so the boiler must have a Written Scheme of Examination and be examined periodically by a competent person.

The machine
Why the RE Doppia matters to the Rocket Espresso owner
Rocket Espresso's commercial machine: Italian build with manual control and a traditional look, aimed at specialty cafés.
In practice you will find it in specialty cafés, espresso bars and roastery sites — which shapes what the examination looks like on site: how the machine is accessed, how long it can be offline, and how much scale it has accumulated.
On the day
- The steam boiler is drained and inspected internally with an endoscope for scale, corrosion and weld condition.
- The safety valve, anti-vac valve and fittings are checked and tested.
- The pressure gauge is verified against our calibrated test gauge, not against itself.
- A 3 group boiler holds more water than a 2 group, so the drain, refill and heat-up all take longer — allow the full appointment window.
- The Written Scheme of Examination names the vessel and the protective devices it covers.

All prices exclude VAT. The additional drain and heat-up time a 3 group boiler needs. We confirm the exact figure on the call.
Filters are fitted on site by an engineer and are not posted out. The filter price applies when ordered with a PSSR examination, service, call-out or water test; booked alone it is charged at the standard call-out.
What we see on this model
- The steam boiler and its protective devices are what the examination covers.
- Dual boiler commercial machine: service boiler 9 L (2gr) / 12 L (3gr), coffee boiler 4 L / 6.3 L; 5 kW (2gr) / 5.8 kW (3gr); steam boiler 0-1.5 bar; coffee boiler 80-100 C; sound pressure <70 dB. Available as RE Doppia/2, /3 and /4. Rocket's user manual does not publish part numbers, so order by description from a Rocket distributor.

Fault finder
What actually goes wrong on a Rocket Espresso RE Doppia
Owners usually call us with a symptom, not a diagnosis. This is what that symptom most often turns out to be on this machine, and what putting it right involves.
| Symptom | Usual cause | What fixes it |
|---|---|---|
| No steam from the wands. | Steam wand sprayer clogged, or the machine is switched off. | Clean the steam wand sprayer; check the machine is on. |
| No coffee dispensed. | Water mains tap closed or the grind is too fine. | Open the mains tap and adjust the grind. |
| Water leaking from the machine. | Drip tray not draining, or the drain pipe is broken, detached or obstructed. | Check the drainage system and re-establish/clear the drain hose. |
| Boiler water goes stale and steam tastes flat. | Water sits in the boiler; Rocket requires periodic renewal. | Have a technician renew the boiler water at least every 3 months, and after any week-long shutdown replace all water in the hydraulic circuits. |
| Brew pressure out of specification. | Pump bypass out of adjustment. | Set brew pressure to 0.8-0.9 MPa (8-9 bar) and boiler pressure to 0.08-0.14 MPa (0.8-1.4 bar); both are monthly/weekly gauge checks. |
These are faults documented for this model, not a generic list.

How much does a PSSR examination cost on a Rocket Espresso RE Doppia?
A standalone examination is £295 + VAT, because the additional drain and heat-up time a 3 group boiler needs. Combined with a front-end service it is £500 + VAT, which is what most specialty cafés, espresso bars and roastery sites choose, since the boiler has to be drained for the examination either way. We confirm the exact figure on the call.
How often does a Rocket Espresso RE Doppia need examining?
The Written Scheme of Examination sets the interval, and for a commercial machine used in specialty cafés, espresso bars and roastery sites it is typically 12 to 14 months. A 3 group boiler holds a larger volume of water, so scale accumulates faster than in a smaller machine on the same duty and the scheme usually sets the shorter interval.
How long does a Rocket Espresso RE Doppia examination take, and what happens on the day?
A 3 group boiler holds more water than a 2 group, so the drain, refill and heat-up all take longer — allow the full appointment window. The visit runs: the steam boiler is drained and inspected internally with an endoscope for scale, corrosion and weld condition. the safety valve, anti-vac valve and fittings are checked and tested. The gauge is then verified against our calibrated test gauge, the system is pressure tested and held, and the machine is re-assembled, refilled, heated and function tested. The Written Scheme of Examination, signed report and asset record follow within 48 hours.
