Wega Polar — PSSR examination & servicing
Polar machines are used in high-street cafés, restaurants and hotel bars 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 Wega Polar 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 Polar matters to the Wega owner
Wega's current mainstream machine, and increasingly the Wega you meet on a new UK install rather than the discontinued Polaris and Pegaso.
In practice you will find it in high-street cafés, restaurants and hotel bars — 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.
Typical rates for this model
- Standalone PSSR examination
- £295
- Service + PSSR bundle
- £500
- Certified safety valve, if it fails
- £55 + VAT
- Water filter, fitted on a visit
- from £107
- Grinder calibration & deep clean
- £89
- If it does not pass
- Explained in writing
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
- A single boiler with heat-exchange groups, so the examination covers one pressure vessel and one set of protective devices.
- Wega machines of this generation use the same boiler schedule as the Polaris they replaced, so findings carry across between the two.
- Current Wega model (not discontinued). Wega catalogue: 'Advanced Boiler' system managing boiler filling and heating, boiler regulation range 0.6–1.4 bar, groups switchable between low (80 mm) and high (125 mm), backlit keypad per group; 4.4–5.2 kW depending on version. No fault documentation exists publicly — leave this page on specification and say so.

Fault finder
What actually goes wrong on a Wega Polar
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 |
|---|---|---|
| Slow heat-up, rumbling element, then element failure | Scale on the element inside the copper boiler. Copper scales faster than steel in hard water and the deposit insulates the element until it fails. | Boiler descale and element check; water treatment is the cheaper fix. |
| Boiler pressure drifts and the element short-cycles | Pressurestat contact burning and drift — the standard wear item on this generation of machine. | Replace the pressurestat and reset the deadband against a calibrated gauge. |
| False fills, or the boiler will not refill cleanly | Level probe fouled or water conductivity changed — the probe reads through the water. | Clean or replace the probe; check the machine's earth. |
| Water under the group, drip tray filling while idle | Anti-vacuum valve or group three-way solenoid passing. | Anti-vac valve and group valve rebuild. |
| Steam wand leaking or not shutting off | Steam tap gland and seat wear. | Tap rebuild kit; complete valve where the body is scored. |
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 Polar?
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 high-street cafés, restaurants and hotel bars 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 Polar need examining?
The Written Scheme of Examination sets the interval, and for a commercial machine used in high-street cafés, restaurants and hotel bars 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 Wega Polar 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.
