Vokera Boiler Red Light On: Your Boiler Isn't A Prostitute - What To Do

Just as boiler brands program fault codes into their appliances, Vokera boilers come with red warning lights designed to alert homeowners to specific issues. 

However, one key distinction between warning lights and error codes is that warning lights are better at bringing your attention to an issue ASAP.

With that said, what is the Vokera boiler red light and what are the potential solutions?

Let’s explore!

Vokera Red Light: What does this Light Mean?

First and foremost, what is the meaning of the Vokera boiler red light? 

Vokera boiler comes with a red and green light.

You may find that one is light on and the other is off or that both the green and red lights are on simultaneously.

Here is what these combinations mean:

• Red Light Off and Green Light On
  In general, you’d expect only the green light to be on at any given time. In this case, it means your boiler is probably working just fine. With that being said, if the green light is flashing there may be faulty hot water sensors, or your boiler is on standby.
  
  

• Red Light On and Green Light Off
  This means that your boiler has entered a lockout for safety reasons. This happens when sensors inside your boiler detect that it isn’t functioning properly. There are several potential causes for this, such as a boiler fan won’t fire up when the boiler is starting up, the pump can’t circulate hot water, or general overheating.
  
  

• Both Red and Green Light On
  However, if both lights are on simultaneously, there are other issues to consider. Also, please note that the lights may be continuous or flashing. In the case of a red and green light together, it may mean that your system’s water pressure is too high or too low or your boiler is stuck in service mode. In the case of water pressure issues, this tends to involve the lights flashing on and off. As for the latter, this may be explained by your boiler being brand new or if it was recently serviced. Alternatively, it’s also possible that the boiler sensors used to monitor the heating temperature have malfunctioned.

Can I Fix a Vokera Red Light by Myself?

This will depend on the nature of the issue.

In some cases, you can do it yourself, while in other scenarios, you’ll need the help of a heating engineer. 

Below we’ve listed the jobs you can do by yourself.

Of course, there’s no guarantee any of these efforts will fix the problem if you’re not sure of the exact cause of the red light (or flashing green light).

If in doubt, it’s probably best to hire a professional regardless of how suitable the task is for DIY work.

Topping Up Your Boiler’s Water Pressure

There are only two jobs you can undertake to solve a Vokera red light by yourself. And both revolve around your boiler’s water pressure.

The ideal boiler water pressure range for a Vokera boiler is 1 to 1.5 bars so if it is below 1 bar it will need topping up. 

Here’s how you can top up a boiler’s water pressure:

• 1. Switch off the boiler. Of course, it should already be cooled down but do double-check this to be on the safe side.
  
  

• 2. Check the filling loop (which can be found beneath the boiler). Ensure that each end is attached and firmly in place.
  
  

• 3. Open both valves and wait until your boiler pressure reaches 1.5 bars.
  
  

• 4. Close each valve, one at a time.
  
  

• 5. Turn your boiler back on. It may also be necessary to hit the reset button after it comes back on.
  
  

• 6. Undo the filling loop and ensure you catch any water remaining in the loop.
  
  

• 7. Clean and keep the filling loop in a secure place.

Please note that this process can vary from boiler to boiler, so do double-check with the manufacturer’s guide before proceeding.

Lowering Your Boiler’s Water Pressure (Bleeding Radiators)

If your boiler water pressure is too high (i.e., above 1.5 bars), then there is one DIY approach that may work as an effort to lower it. That is to bleed your radiators.

To do so, you can take the following steps:

• Turn the heating off and allow your radiators the chance to cool down (although we assume they already are).
  
  

• Put a towel under the bleed valve of the first radiator you plan to bleed. Put a jug on top of the towel (again just beneath the bleed valve). The purpose of the towel and jug is to catch excess water.
  
  

• Stick the bleed key into the radiator. Gradually turn it anti-clockwise.
  
  

• Once the air starts escaping, you should hear a hissing sound. Once the water starts coming out of the bleed valve, you need to close it. You can do this by turning the bleed key clockwise, and returning it to its initial position. Depending on how easy it is to tell, you may need to keep track of how far you turn it originally so you can turn the bleed key back to its initial position at this stage.
  
  

• Repeat these four steps with each radiator in your home.
  
  

• Once you’ve done everything and are satisfied, you can turn your heating back on. Check to see if a) your radiators are working more efficiently and b) more importantly, whether your boiler pressure has gone back down.

Again, as with topping up your boiler pressure, do ensure you check the Vokera guide for bleeding your radiators to be sure you take all the correct steps.

If in doubt, hire a professional.

Cost of Hiring a Heating Engineer to Fix a Vokera Boiler Red Light

On average, it costs between £30 and £60 an hour in labour costs to hire a Gas Safe Register engineer.

However, labour costs can vary based on factors such as where in the UK you are located. Add to that the price of supplies and you have the total estimated cost of any given boiler repair or replacement job.

This would be the case if your current one is particularly old, and the cost of a repair or replacement job is substantial enough such that it’s more financially viable to just replace your boiler.

Here is the cost of specific fixes for a Vokera red light:

• Repair or replace boiler fan
  £60 to £480
  
  

• Repair or replace boiler pump
  £60 to £480
  
  

• Fix an overheating boiler
  £30 to £120
  
  

• Topping up boiler water pressure
  £30 to £60
  
  

• Lowering boiler water pressure
  £30 to £120
  
  

• Repairing or replacing faulty hot water sensors
  £40 to £160
  
  

• Replacing an entire boiler
  £800 to £2,800

Will my Warranty Cover Repairs or Replacement Work for an F22 Fault?

Vokera, like most boiler brands, only covers repair or replacement work if related to defects that are the result of the workmanship or material of the manufacturer.

So, in short, probably not.

Moreover, even if the repair/replacement job needed to fix the F22 error does fit the above description, it’s essential to verify that your warranty is still active.

For instance, in order to keep a Vokera warranty valid, you must be serviced annually by a Gas Safe Registered Engineer.
