Safety First

Smell gas? Turn off the gas supply at the meter if it is safe to do so. Open windows. Leave the property. Call the National Gas Emergency Service on 0800 111 999. Do not use switches, and do not use naked flames.

CO alarm sounding? Stop using the boiler. Open doors and windows. Leave the property. Call the National Gas Emergency Service on 0800 111 999. If anyone is drowsy, breathless or has a headache, call 999 as well. Do not re-enter until you are told it is safe.

Boiler leaking heavily? Turn off the boiler at the controls. If safe, turn off the water supply. Call an engineer.

Quick Checks Before You Call

Before calling an engineer, these safe checks may resolve simple issues with your Vokera boiler.

Check the gas supply

Is gas working at other appliances in your home? If not, check your meter and any prepayment credit.

Check the pressure gauge

Pressure should read around 1.0 to 1.5 bar when cold. If below 1 bar, you may need to repressurise using the filling loop.

Check the thermostat

Is the room thermostat set above current room temperature? Are the batteries working?

Check the timer or programmer

Is the heating scheduled to be on? Check the clock is set correctly.

Try a single reset

Locate the reset button on your Vokera boiler. Press once and wait. If the fault returns, do not keep resetting. Call an engineer.

Check the condensate pipe

In cold weather, the external condensate pipe can freeze. Look for a white plastic pipe exiting through an outside wall. If frozen, pour warm water over it gently.

Vokera Fault Codes

Common Vokera fault codes and what to do

Code/What It Means/What To Do

A01 Ignition failure (no flame established)

Check gas supply and other appliances. Check condensate pipe in freezing weather. If still locked out, call an engineer.

A04 Ignition lockout (multiple failed attempts)

Check gas supply and condensate pipe. If still locked out, call an engineer.

A06 Low water pressure

Top up pressure using filling loop (see below). If it drops again within days, call an engineer.

A08 Flame lost during operation

Reset once. If it happens again, call an engineer.

A10 Flue sensor fault

Call an engineer.

A12 No circulation detected

Check radiators are getting hot. If circulation seems poor, call an engineer.

A03 Fan fault

Call an engineer.

Note: Vokera uses A codes on most models. If unsure, call us and we will help you identify your specific code.

Not sure which fault you have?

Call with your model and the code on the display. We will tell you what is likely involved before anyone attends.

Most Searched Vokera Problems

If you are seeing a lockout, loss of hot water, or your Vokera boiler keeps resetting, tell us the fault code and model and we will confirm the safest next step.

A01 / A04 – ignition failure

A01 and A04 are the most common Vokera fault codes. The boiler tries to ignite but no flame is established, or locks out after multiple failed attempts. Common causes include gas supply issues, a faulty ignition electrode, or a blocked condensate pipe in winter. Check gas is on elsewhere in the home. Try one reset. If the lockout returns, stop and call an engineer.

A06 – low pressure

If your Vokera shows A06, system pressure has dropped below the minimum threshold. Top up via the filling loop to around 1.0 to 1.5 bar when cold. If pressure drops again within days, there may be a leak in the system or a failing expansion vessel. Call an engineer to find the cause.

A12 – no circulation

A12 indicates the boiler has detected poor or no flow through the system. Check your radiators are getting hot. If circulation seems poor, there may be a pump issue, airlock, or sludge buildup. Call an engineer to diagnose and repair.

No hot water but heating works

On Vokera combi boilers, you may get heating but no hot water, or the reverse. This often points to a diverter valve issue. The diverter valve directs hot water between taps and radiators. When it wears or sticks, hot water delivery becomes unreliable. Call an engineer for diagnosis.

Why Vokera Boilers Develop Faults

Vokera is part of the Riello Group and manufactures a range of boilers in the UK. Here is what we commonly see.

Ignition electrode wear

Ignition faults (A01, A04, A08) can occur when the ignition electrode wears or becomes coated with carbon. Condensate blockages in winter can also contribute to repeated lockouts.

Low pressure and expansion vessel faults (A06)

Low pressure faults often point to a failing expansion vessel or a weeping pressure relief valve. The expansion vessel absorbs pressure changes as water heats and cools. If the diaphragm fails or the air charge is lost, pressure drops can occur.

Circulation and pump issues (A12)

A12 can indicate poor circulation through the system. This may be caused by a failing pump, sludge buildup, or closed radiator valves. A powerflush may help restore flow.

Fan and flue faults (A03, A10)

Fan faults prevent safe combustion and flue gas extraction. The boiler will lock out for safety. Causes include fan motor failure, wiring faults, or flue sensor issues.

Diverter valve on combi boilers

The diverter valve directs hot water between your taps and radiators. When it wears or sticks, you may get heating but no hot water, or the reverse.

Repair or Replace Your Vokera Boiler?

We help you decide based on age, reliability, and parts availability.

Repair makes sense when

  • Boiler is under 10 years old
  • This is the first major fault
  • Parts are readily available
  • Boiler has been regularly serviced

Replacement may be better when

  • Boiler is 12 to 15 years old or more
  • You have had multiple breakdowns recently
  • Parts are obsolete or hard to source
  • The boiler is undersized for the property
  • Energy bills are higher than expected for the property size

Our engineers give honest assessments. We focus on safety and reliability, not pushing unnecessary replacements.

Vokera Boiler Servicing

Annual servicing reduces breakdown risk and keeps your Vokera boiler running efficiently. See Boiler servicing London.
