Wega Pegaso — PSSR examination & servicing
Pegaso machines are used in cafés, pubs, small restaurants and contract 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 £265 + VAT, or £440 + VAT with the service included.
Quick answer
Does a Wega Pegaso 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 Pegaso matters to the Wega owner
A straightforward mechanical workhorse favoured for low maintenance costs.
In practice you will find it in cafés, pubs, small restaurants and contract 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 single compact boiler drains and refills quickly, which makes this the shortest appointment we book.
- The Written Scheme of Examination names the vessel and the protective devices it covers.
Typical rates for this model
- Standalone PSSR examination
- £265
- Service + PSSR bundle
- £440

- Explained in writing
All prices exclude VAT. A single steam boiler with one set of protective devices to examine. 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
- Mechanical machines have fewer failure points and cheaper repairs, so a combined service and examination is particularly good value here.
- Older mechanical builds sometimes carry gauges that no longer read accurately — we check against our own calibrated gauge as part of the examination.
- No Pegaso fault or service document is public — Wega's technical material sits behind a dealer portal, and no model-specific fault thread or manual was retrievable. Documented specification (UK dealer sheet): 2-group 10.5 L copper boiler, 3.4 kW, 13/20 A; 3-group 16 L boiler, 5.0 kW, 20/30 A; four programmable doses per group plus manual override, two steam wands. Present this model as specification only, not as a documented fault list.

Manufacturer's published boiler capacities. Where a maker publishes no figure we say so rather than estimate.
Service interval. No Pegaso-specific interval is published. Wega's manual for the Polaris in the same range recommends a general check by the service centre at least once a year; no Pegaso document found states its own.
Fault finder
What actually goes wrong on a Wega Pegaso
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 |
|---|---|---|
| Steam wand drips when closed or steam is weak | DESIGN INFERENCE: Pegaso uses the same Wega steam valve family as Polaris, so the same seal and O-ring wear applies | rebuild the steam valve. |
| Unstable steam pressure, element short-cycling, occasional spurious boiler fill or overfill | DESIGN INFERENCE: sticking pressurestat and scale on the level probe - the standard failure pair on a pressurestat-controlled HX machine | clean the probe, recalibrate or replace the pressurestat. |
These are the failure modes implied by this machine's boiler type, layout and duty, rather than a list published for this exact model.

How much does a PSSR examination cost on a Wega Pegaso?
A standalone examination is £265 + VAT, because a single steam boiler with one set of protective devices to examine. Combined with a front-end service it is £440 + VAT, which is what most cafés, pubs, small restaurants and contract 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 Wega Pegaso need examining?
The Written Scheme of Examination sets the interval, and for a commercial machine used in cafés, pubs, small restaurants and contract sites it is typically 12 to 14 months. A single boiler on this duty normally sits at the middle of that range unless the water is hard, which we test on the day and report with the certificate.
How long does a Wega Pegaso examination take, and what happens on the day?
A single compact boiler drains and refills quickly, which makes this the shortest appointment we book. 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.
