Conti CC100 — PSSR examination & servicing
CC100 machines are used in independent cafés, restaurants and wholesale supply contracts 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 Conti CC100 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 CC100 matters to the Conti owner
A budget-friendly, highly reliable option distributed extensively by wholesale coffee suppliers.
In practice you will find it in independent cafés, restaurants and wholesale supply contracts — 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.

- 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
- Machines supplied as part of a coffee contract are frequently missing their Written Scheme — the wholesale invoice is not a compliance document.
- If your roaster supplied the machine, we can invoice you directly and keep the compliance record separate from the coffee supply.
- Single boiler - the manual lists total, hot-water and steam volumes rather than a separate coffee boiler: 5 L total on 1 group, 11 L on 2 group, 18 L on 3 group (hot water 4/8/13 L, steam 1/3/5 L). Installed power 2700 / 3600 / 5000 / 6300 W across CC101i / CC102i / CC103i / CC103i Tri. Boiler pressure set 0.08-0.1 MPa, pump 0.9 MPa. Group backflush is automatic from the keypad (key 5 + key 1).

Fault finder
What actually goes wrong on a Conti CC100
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 |
|---|---|---|
| Machine will not fill and LEDs L2+L3 flash | 'ALARM TIME OUT 1ST FILLING' - the electronics received no signal from the level probe for more than 360 seconds | check water supply, inlet filter and level probe, then reset. |
| A group stops mid-service, and eventually the pump stops too | 'ALARM FLOWMETER' - no pulse for more than 4 seconds, after 45 seconds the board stops that group's solenoid AND the pump | check the flowmeter and its wiring, clear any restriction. |
| Machine stops heating, L1+L4 indicate | 'ALARM TEMPERATURE SENSOR DISCONNECTED' - probe disconnected for more than 3 seconds, so the board cuts the SSR | reconnect or replace the probe and its loom. |
| Machine trips out on over-temperature | 'OVER TEMPERATURE ALARM' - boiler above 140 deg C for more than 5 seconds, the alarm clears when temperature drops below 125 deg C | find the overshooting thermoregulation device (probe, pressure switch, SSR). |
| Preventive service | Conti publishes the kits: half-year 470891 (group gasket, sprinkler, clean the level probe of limestone deposit), annual 470892 (pump inlet filter, vacuum valve, safety valve, non-return gaskets, 12 bar limiter gasket, solenoid seats, tap O-rings) | fit the kit at the stated interval. |
| Machine will not fill; LEDs L2 and L3 on all groups flash. | 'ALARM TIME OUT 1ST FILLING' - the electronics received no signal from the SN level probe for more than 360 s on first fill. | Check water supply and inlet filter, then the level probe and its connection; the boiler only heats once the level probe is reached. |
| Coffee stops mid-shot; all LEDs on the affected group flash. | 'ALARM FLOWMETER' - the motherboard received no pulses from that group's flowmeter for more than 4 s. | Check the flowmeter and its connection; after 45 s the board shuts that group's solenoid and the pump, so clear the fault and restart. |
| Heating stops; LEDs L1 and L4 on all groups flash. | 'ALARM TEMPERATURE SENSOR DISCONNECTED' - no signal from the boiler temperature sensor for more than 3 s; the electronics cut the solid-state relay. | Check the probe and its wiring; replace the sensor if open circuit. |
| Machine cuts out with LEDs L3 flashing on all groups. | 'OVER TEMPERATURE ALARM' - boiler above 140 C for more than 5 s; heating management stops automatically. | Let it fall below 125 C to clear, then find why it overshot: probe, solid-state relay or board. |
These are faults documented for this model, not a generic list.

How much does a PSSR examination cost on a Conti CC100?
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 independent cafés, restaurants and wholesale supply contracts 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 Conti CC100 need examining?
The Written Scheme of Examination sets the interval, and for a commercial machine used in independent cafés, restaurants and wholesale supply contracts 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 Conti CC100 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.
