Crem & Expobar Diamant Pro — PSSR examination & servicing
Diamant Pro machines are used in hotels, banqueting halls and high-volume catering 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 Crem & Expobar Diamant Pro 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 Diamant Pro matters to the Crem & Expobar owner
A robust commercial machine popular in high-volume hotels and banqueting halls.
In practice you will find it in hotels, banqueting halls and high-volume catering — 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
- Banqueting machines run flat out for events and sit idle between them — idle periods are the ideal examination window.
- High-volume catering should pair the statutory examination with a filter programme; scale is what shortens the life of these boilers.
- Crem International (Gandia, Spain) builds Expobar and Crem from the same platform. Alarm wording above is the machine's own, from Crem's Diamant user manual (1764214_01). The GICAR control board is the other known failure point on this platform - when the display and buttons go dead the display head and the GICAR board are the two suspects.

What actually goes wrong on a Crem & Expobar Diamant Pro
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 |
|---|---|---|
| Shots run cold or groups stop delivering water altogether, boiler and pipework feel scaled | limescale in the heat-exchanger outlet pipes and the water system, usually a neglected softener | descale or replace the affected HX pipework and group circuit, and restore proper water treatment. |
| Display and buttons dead or intermittent - the machine heats but will not respond | failed display or GICAR control unit, on this machine the display head carries the group-boiler control logic | replace the display/GICAR unit, and on multi-boiler versions check the group-boiler control side. |
| 'Flowmeter X' alarm and the group will not dose, or the dose light flashes and nothing happens | no pulses from that group's flowmeter - scale or debris in the meter, wiring, or a dead meter | strip and clean or replace the flowmeter, check the plug and loom. |
| 'Tprobe Unconnect' or a temperature-sensor alarm, boiler temperature control lost | boiler temperature probe open circuit or disconnected - probe, plug or loom | re-seat the probe connector, then replace the probe. |
| Water on the floor or in the base of the machine after service | drain cup or tube blocked with grounds, or the drain tube has come off the cup | clean the drain cup and tube, reconnect and re-route so it cannot kink. |
| Steam wand stops steaming although the boiler is up to pressure | nozzle or tip clogged with dried milk | remove the nozzle and unclog it with a pin, clean the wand. |
| 'Flowmeter X Alarm' and that group will not dose. | No water flow detected by flowmeter X - scale or debris in the meter, a stuck turbine, or a wiring/plug fault. | Strip and clean or replace the flowmeter, check the plug and loom. |
| 'Tprobe Unconnect' / temperature sensor warning; boiler temperature control lost. | Temperature sensor not functioning: open-circuit probe, unseated connector or damaged lead. | Re-seat the probe connector, then replace the probe. |
| 'No Water' warning and the machine will not brew. | The machine is not receiving water - mains, filter, or the inlet solenoid. | Restore supply, clean the inlet filter, test/replace the inlet solenoid. |
| Cold shots, or groups stop delivering water; boiler and pipework feel scaled. | Limescale in the heat-exchanger outlet pipes and water system - Crem states 90% of faults are limescaling from unsoftened water. | Descale or replace the affected HX pipework, restore proper water treatment. |
| Water under the machine; steam wand stops steaming. | Drain tube blocked or disconnected; steam nozzle clogged with dried milk. | Clean/reconnect the drain cup and tube; unclog the nozzle with a pin and soak. |
These are faults documented for this model, not a generic list.

How much does a PSSR examination cost on a Crem & Expobar Diamant Pro?
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 hotels, banqueting halls and high-volume catering 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 Crem & Expobar Diamant Pro need examining?
The Written Scheme of Examination sets the interval, and for a commercial machine used in hotels, banqueting halls and high-volume catering 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 Crem & Expobar Diamant Pro 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.
