A constant red light on your Vokèra boiler means that the unit has gone into lockout for safety reasons. Some of the possible faults behind this include: The boiler is overheating. The pump isn’t circulating hot water around the central heating system or to the taps when required.
Why is the red light on my boiler flashing?
Usually, when modern boilers need resetting they will display a fault code or begin to flash a red or green light. These signals indicate that your boiler senses a problem, which is why it has stopped working and needs to be reset.
Why does my Vokera boiler keep cutting out?
There are many possible reasons why a Vokera boiler will fail to ignite: faulty ignition leads or electrode (needed to make the spark to create the flame), blocked flue or condensate pipe, issue with the gas valve or a printed circuit board (PCB) fault.
How do I reset my boiler?
- Refer to your boiler manual.
- Push the reset button for 10 seconds.
- Wait 2 – 3 minutes, the boiler should fire up.
- Repeat twice if the first attempt fails.
- If the boiler still fails to fire up on the third attempt, double check the gas supply.
How do I fix the red light on my boiler?
A simple reset could be enough to stop your Vokera boiler from flashing red and get the unit working to heat your home and hot water again. To reset your Vokera boiler, move the mode selector switch to the ‘OFF/RESET’ position and then move it back to either ‘hot water only’ or ‘heating and hot water’.
What happens if boiler pressure is too low?
If the pressure on your boiler is too low, then your central heating may not work, and if it’s too high, then it will be under too much strain and could also be prevented from working.
Can a boiler explode?
While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.
How do you fix a low pressure boiler?
- Switch off and allow your boiler to cool.
- Double-check that both ends of the filling loop are securely attached.
- Open both valves, to allow cold mains water into the system (you should hear it)
- Wait for the pressure gauge to read 1.5 bar.
- Close both valves, one after the other.
What number should boiler pressure be on?
The ideal pressure for your boiler is usually between 1 and 2 bars, but it’s possible it could go up to 2.5 bars when your heating is on. Check the boiler manual to find out exactly what it should be for your boiler make and model. If the boiler pressure is below 1, that means low pressure.
How do I turn my boiler back on?
Locate the pilot on the left side of the burner. Press and turn the gas control knob counter-clockwise to “Pilot.” Press the knob in and immediately strike a match and light the pilot. Continue holding the control knob in for one minute. Then let go and check to see if the pilot remained lit.

Why is my Vokera boiler flashing green?
Flashing green lights When the green light is constantly on it means the flame is working, but a flashing green light could be due to a faulty hot water sensor or because it is in standby. A reset may be enough but if not you may need to get in touch to arrange an engineer to diagnose the issue.
How much is a new boiler?
Boiler Replacement Cost. The cost of replacing a standard gas boiler is about $4,000. A high-efficiency model costs about $7,500. This cost estimate usually includes removal and disposal of the old unit, as well as all necessary lines and wiring needed for the new system to run properly.
Should my boiler be hot to touch?
So to answer the main question – “Should my boiler be hot to the touch?” – the answer is no, but some will indeed get quite warm. Remember that an overly warm boiler is almost certainly an inefficient one, as heat will be leaking out around it rather than into the cylinder, radiators and taps.
Can a boiler explode if it's turned off?
When boilers are sealed off, some water will remain and will eventually be heated to form steam, creating pressure. As internal pressure builds up, the jacket can explode because of the lack of water.
What happens if boiler pressure is too high?
If the boiler pressure is too high, there’s an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won’t work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.
Should boiler pressure go up when heating on?
What should your pressure be? The ideal boiler pressure should be between 1 to 1.5 bars on your pressure gauge when your heating is switched off. Around 2 bars is a normal pressure level when your boiler is active/heating up. Anything below 0.5 is too low and must be replaced.
Is 2 bar too high for a boiler?
What Boiler Pressure Is “Too High”? Anything above a boiler pressure of 1.5 bar isn’t ideal. 2 bar starts to become more serious and when most boilers hit 3 bar, they’re in the red zone on the pressure gauge. So, the unit is likely to lock out and display a fault code.
What pressure should boiler be cold?
What Pressure Should My Boiler Be When It’s Cold? The boiler pressure should be between 1, to 1.5 bar. Most manufacturers recommend an optimal working pressure of 1.3 bar . Always refer to your owner’s manual.
What happens if a boiler runs out of water?
Boiler Failure If a boiler has enough water, the steel will never reach temperatures high enough to weaken it. In a dry fire accident, there is no water to moderate the temperature. As a result, the boiler’s steel can overheat, warp and crack at the welds.
Why would a boiler not ignite?
A boiler might not ignite due to various possible reasons – insufficient pressure, blockage in the burner, faulty valves, frozen pipes etc. Sometimes, you can fix the problem on your own. In other cases, you don’t have any choice but to call an engineer.
How long does a boiler take to turn on?
Providing the tank has hot water in it, you’ll be able to access instant hot water when you turn on a tap. However, when the tank is empty, it takes an average of 20-30 minutes for more water to be heated, depending on the boiler model you have installed.
Can a boiler last 20 years?
The life expectancy of a boiler depends on the type of boiler you have. On average, a conventional gas boiler can last for 10 to 15 years given that it is well maintained and serviced annually. If you have a superior quality boiler and it’s well maintained, you can expect it to last for 20 years and more.
What does A04 mean on boiler?
When a Vokera boiler shows an A04 fault code on the display panel, it means that the system has insufficient water pressure. For a boiler to work, the system needs to have enough water pressure. If it has too much or too little it will lock out and display a fault code, in this case the A04.
Is Vokera a condensing boiler?
All Vokera boilers are condensing boilers. Since 2005, it has been a legal requirement for new domestic gas boilers to be condensing, unless this is not possible. As well as combi, system and conventional boilers, Vokera also makes water heaters, hot water cylinders, solar thermal panels and heat pumps.
How do you flush a central heating combi boiler?
Switch off the boiler when the heat reaches to about 45°. You should do reversing the flow of the power flush in every ten minutes. Close all other radiators, but except one to allow through, repeat the same process with all other radiators. Open all of the radiator valves and allow the flush to flow freely.
How do I get the water out of my boiler?
- Step 1: Do a Quick Flush. …
- Step 2: Turn off Your System. …
- Step 3: Open the Drain Valve and Flush the Tank With Water. …
- Step 4: Refill Your Hot Water Heater. …
- Step 5: Relight the Water Heater and Check the Drain Valve.
Do you bleed a radiator when it is on or off?
Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.
What does lock out mean on boiler?
Your boiler has probably gone into ‘lockout’, which is when it shuts down because it’s detected a problem. The good news is that if it’s a common fault, you may not have to call in a boiler engineer. The first thing to do when your heating goes out is check the power in your home, and the pressure in your boiler.
