Common Vokera faults, fault codes, safe checks, and when to call a Gas Safe engineer.
⚠️ Safety First
Smell gas? Do not touch anything. Do not use switches. Open windows, leave the property, and call the National Gas Emergency Line: 0800 111 999.
Carbon monoxide alarm sounding? Get everyone out immediately and call 999. Learn more about carbon monoxide safety.
No gas smell, no alarm? Your boiler may have locked out as a safety precaution. Try the quick checks below.

Quick Checks Before You Call Anyone
These take 60 seconds and solve a surprising number of lockouts:
- Check the pressure gauge: If below 1 bar, top up (see guide below). More detail in our complete pressure guide.
- Note the fault code: Vokera displays show A codes like A01, A04, A06. Write it down before calling.
- Check your fuse box: Boilers need electricity; a tripped switch is an easy fix.
- Check thermostat and timer: Settings can change after clock changes or dead batteries.
- Freezing weather? The condensate pipe may be frozen (see winter section below).
- Reset once only: Press the reset button on the front panel (or follow the display prompt), wait 60 seconds. If it locks out again, stop and call an engineer.
Vokera Boilers Commonly Found in London
Vokera boilers are frequently installed in London flats and smaller houses, where space-saving combis like Mynute, Compact, and older Linea models are common. We also see Easi-Flo combis and Synergy system boilers in properties with cylinders. Many older installs are now in the “wear-and-tear” phase where ignition components, fans, diverter valves, and circulation issues become more likely.
Vokera Fault Codes
Note: Vokera uses A codes on most models. Fault codes can vary slightly between Vokera model ranges and control panels. If unsure, call us and we’ll identify your exact model and code.
| Code | What It Means | What To Do |
|---|---|---|
| A01 | Ignition failure (single event) | Check gas supply and other appliances. Check condensate pipe in freezing weather. If still locked out, call engineer. |
| A04 | Ignition lockout (multiple failed attempts) | Check gas supply and condensate pipe. If still locked out, call engineer. |
| A06 | Low water pressure | Top up pressure using filling loop (see below). If it drops again within days, call engineer. |
| A08 | Flame lost during operation | Reset once. If it happens again, call engineer. |
| A10 | Flue sensor fault | Call engineer. |
| A12 | No circulation detected | Check if radiators heat evenly and listen for pump operation. If circulation seems poor, call engineer. |
| A03 | Fan fault | Call engineer. |
| A14 | Overheat lockout | Do not repeatedly reset. Let it cool. If it returns, call engineer. |
A04: Ignition Lockout
What is happening: The boiler has attempted to ignite multiple times and failed, triggering a lockout. This is the most common Vokera fault code.
Common causes: Frozen condensate pipe (winter), gas supply interruption, faulty ignition electrode or lead, blocked or damaged flue, gas valve fault.
What to try: Check if your gas hob or other gas appliances work. In freezing weather, check the condensate pipe for ice. If gas supply is fine but boiler will not ignite, call an engineer.
Note: A01 indicates a single ignition failure, while A04 triggers after multiple failed attempts. Both point to ignition problems, but A04 is more persistent.
A12: No Circulation Detected
What is happening: The boiler is not detecting adequate water flow through the heat exchanger.
Common causes: Pump failure, airlocks in the system, blocked or restricted pipework, sludge buildup, faulty flow sensor.
What to try: Check if radiators are heating. If some are cold at the bottom, there may be sludge. If the pump is not running (no vibration or noise), call an engineer. A power flush may be needed if sludge is suspected.
A14: Overheat Lockout
What is happening: The boiler detected excessive temperature and shut down for safety.
Common causes: Restricted circulation, pump failure, limescale in heat exchanger, system sludge, faulty thermistor.
What to try: Nothing user serviceable. Do not repeatedly reset. Let it cool down. Call a Gas Safe engineer. If circulation or sludge is the cause, a power flush may be recommended.
A10: Flue Sensor Fault
What is happening: The boiler is detecting a flue/combustion safety condition and may lock out to protect you.
What to do: This is not user serviceable. Do not remove covers or attempt adjustments. Call a Gas Safe engineer.
A06: Low Water Pressure
What is happening: System pressure has dropped below the minimum operating level.
Common causes: Small leak in system, recently bled radiators, pressure relief valve discharge, expansion vessel needs recharging.
What to try: Top up pressure using the filling loop (see below). If pressure drops again within days, there may be a leak. If pressure rises towards 3 bar when the heating is on, the expansion vessel may need recharging. Read our pressure guide for step by step instructions.
How to Top Up Pressure (Vokera)
If you are not comfortable using the filling loop, stop and call a Gas Safe engineer.
Note: Some Vokera installations use an internal filling key/lever rather than a braided hose. If you cannot clearly identify the filling method, stop and call.
- Locate the filling loop (usually underneath the boiler, a braided silver hose with one or two valves).
- Ensure the boiler is off and cool.
- Open the valves slowly, a quarter turn at a time.
- Watch the pressure gauge rise to between 1.0 and 1.5 bar.
- Close both valves fully.
- Switch the boiler back on.
Do not exceed 2.0 bar. If you overfill, stop and call an engineer.
If you need to top up frequently (more than once a month), there is likely a leak or expansion vessel issue. Call us for a diagnosis.
Frozen Condensate Pipe (Winter)
In freezing weather, a frozen condensate pipe is one of the most common causes behind A01 and A04 lockouts on Vokera boilers. This is often safe to resolve with the steps below. If you are unsure, or the boiler will not restart, call an engineer.
Signs: Boiler locked out with A01 or A04, freezing temperatures outside, gurgling sound when boiler tries to start.
What to do:
- Locate the condensate pipe (white or grey plastic pipe exiting to an outside drain).
- Pour warm water (not boiling) over the frozen section.
- Reset the boiler once thawed.
Do not use a naked flame or heat gun on plastic pipework.
Full instructions: Frozen condensate pipe guide.
If it keeps happening, we can reroute the pipe internally or add insulation to prevent future freezing.
Why These Faults Are Common in London Homes
Hard water, older pipework, and winter weather make certain faults more likely in London properties:
- A01/A04 ignition failures: Frozen condensate pipes during cold snaps are a frequent cause. Older Vokera models also have ignition components that wear over time.
- A12 circulation faults: London’s hard water causes sludge and limescale buildup, restricting flow and triggering circulation errors.
- A14 overheat lockouts: Sludge restricts flow through the heat exchanger, causing the boiler to overheat and lock out for safety.
- Pressure fluctuations: Older London properties with microbore pipework or poorly balanced systems experience more A06 low pressure faults.
- Fan and flue issues: Some London properties have challenging flue routes that can cause A03 or A10 faults in windy conditions.

Common Vokera Problems
Ignition failures (A01/A04): The most common Vokera repair. Often caused by worn electrodes, faulty spark generator, or gas valve issues.
Fan faults (A03): Fan not running at correct speed or failing to prove to the PCB.
Diverter valve sticking: Hot water works but radiators stay cold, or vice versa. Common on models over 8 years old.
PCB failure: Random lockouts, display glitches, or complete failure.
Pump failure: No circulation (A12), overheating (A14), radiators not heating evenly.
Heat exchanger blockage: Kettling noises, overheating, reduced efficiency. See our guide to boiler noises.
Repair or Replace?
Vokera boilers typically last 10 to 15 years with proper maintenance. If yours is approaching that age and needs a major repair (heat exchanger, PCB), replacement may be more cost effective.
Older models like the Excell and early Linea boilers may have limited parts availability. If your boiler needs multiple major repairs or the same fault keeps returning, replacement is often more economical.
We give honest advice either way. Read more: Repair or replace? An engineer’s guide.
If you decide on a new boiler: New boiler installation.
🔧 Vokera Circulation Problems, Kettling, or Cold Radiators?
If your Vokera is showing A12 circulation faults, A14 overheat lockouts, making kettling noises, or has cold spots on radiators, the cause is often sludge or limescale restricting flow.
London is a hard water area, and over time debris builds up. A power flush clears the system and can restore proper circulation. Learn more about power flushing.
Vokera Servicing
Annual servicing keeps your Vokera running efficiently and maintains your warranty. We service all Vokera models and provide a full report after each visit.
We recommend servicing in late summer or early autumn, before the heating season. Book your boiler service.
