Vokera are a cheaper boiler brand in comparison to companies like Vaillant and Worcester, which does also tend to mean that they run into a few more problems as a result. For many homeowners they offer a cheaper alternative to other brands, although this does often come with a downside of having to pay for additional repairs, and in more serious cases where a replacement is needed it can require new boiler installation.
We’ve put together a troubleshooting guide for Vokera boilers to help you diagnose the problem and also tell you how each one can be solved. In some cases, you will need a Gas Safe registered engineer to help, and if you’re based in London please do get in touch with us and we’ll be very happy to support.
Owners of Vokera Vision boilers can experience issues with the ignition, with loud gurgling noises heard when the boiler is turned on. The ignition part can be easily changed, although if the issue is linked to a faulty PCB board it may be a more expensive issue to resolve.
Common Vokera Compact 29a problems include the ‘03’ error code. This is typically associated with the fan, as parts used in Vokera boilers tend not to be of the highest quality and can breakdown. Fans are usually quite straightforward to be replaced – and installing the entire fan is usually a better long-term option to reduce the likelihood of it happening again.
If you experience fault code ‘73’ or ‘79’ this is one of the common Vokera Mynute 20e problems owners can experience. It indicates a fault return thermistor, which should be a straightforward part to replace if that is the root of the issue. Other Vokera thermostat problems can be linked to a limit temperature fault, while other Vokera thermostat error codes can be linked to low temperature issues.
Look out for Vokera boiler ‘01’ error code which appears when the boiler fails to ignite. If resetting doesn’t work then get in touch with us to arrange an engineer. Error code ‘03’ appears because of a faulty fan or flue. As above, if resetting does not resolve the issue Homecure will be able to help.
When it is too low, Vokera boiler water pressure will produce error codes ‘40’, ‘41’ and ‘A04’ on Linea and Compact models. This will mean affect performance levels and a Vokera boiler with low pressure could be due to a leak in the system. If you suspect a leak, get in touch with us right away so an engineer can diagnose and repair.
Vokera boilers with a red light flashing indicates a problem that needs to be fixed. On a Compact model it may produce the ‘A01’ code with a red light that showing an ignition issue. Flashing red lights and red lights that remain without flashing will mean different things and will be something our engineers can help fix.
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.
You may have a problem with the diverter valve if the water is not getting hot or only gets warm when the heating is turned on. This is a common problem with Flowmatic and Unica HE boilers, but it doesn’t always have to mean the entire diverter unit has to be replaced. This is something a Homecure engineer can assess and repair in a short amount of time.
If the condensate trap or pipe is blocked you will see error codes ‘92’, ‘93’ or ‘95’ displayed. A blocked pipe can usually be unblocked outside by pouring warm water overs it until it thaws. If this doesn’t do the trick there may be debris in the pipe that needs to be cleaned out which can be done by removing the pipe and running water through it.
When a Vokera boiler is making whistling, banging or gurgling noises it could be due to low water pressure in the system (which could also indicate a leak) or kettling. In either situation you should get in touch with Homecure to arrange for an engineer to visit and resolve the issue for you.
We are experts at Vokera boiler troubleshooting and can diagnose and repair any problem you are experiencing with your system. Homecure have a team of professional Gas Safe engineers who are available to provide boiler repairs at short notice. Get in touch with us today to make an appointment.
Should I call a Homecure engineer?
Banging noises or whistling
This could be due to a leak, or could be related to an ignition problem.
No heating or hot water
Can be caused by faulty diverter valves and may produce red flashing lights on the system.
There may be a leak in the system – especially if it continues to happen – or an issue with a valve.
Yes – if it is a leak. If refilling the system to reduce, or bleeding the radiators, to increase the pressure, does not work, get in touch.
Leaks can happen anywhere in the system and may not always be visible. They need to be addressed and fixed right away.
Boiler shutting down
Could be a faulty air pump or thermostat causing the issue and a part needs to be replaced.
Problems with thermostat
Usually a limit or low temperature fault that requires the thermostat to be replaced. May also be related to timing and temperature settings.
Yes – if resetting the timings/temperature does not resolve the problem.
Frozen condensate pipe
Usually just needs warm water to be poured over the external pipe so it thaws out.
Yes – if after thawing the pipe is still blocked there may be another reason for the issue.
No pilot light
The thermocouple may need to be replaced if the boiler is not lighting up.
If there is too much limescale or sludge in the system water will struggle to pass through the radiator to warm them up.
Maybe – bleed the radiators to see if this fixes the problem. If not, get in touch with us to arrange a booking.
This can be another issue related to limescale or sludge in the system that needs to be cleared.
Maybe – bleed the radiators but contact us if the noises persist.
To reset a Vokera boiler change the mode selector to ‘Off/Reset’. Then move it back to ‘Heating and Hot Water’ or ‘Hot Water Only’. This should reboot the system so it starts to work again. If not, get in touch with Homecure who can arrange for an engineer to check the boiler.
Vokera boilers will last for different lengths of time depending on usage, installation and how well-serviced it is. Vokera boilers come with a 12-month warranty as standard, although this can be extended to up to 7 years.
How you fix pressure on a Vokera boiler depends on why the pressure is too high or low. A Vokera boiler can be re-pressurised by following the manual instructions if the bar is below 1. But if you have a leak or another issue it may start to fall or rise again. If this happens a Homecure engineer can help fix this.
The pressure gauge on a Vokera boiler should be between 1 and 1.5. If it rises or falls substantially above or below this for an extended period of time you will likely have a pressure issue that needs to be fixed. This is something Homecure engineers diagnose and repair every day.
A Vokera boiler flashing red is likely due to a lockout, which will prevent heating and hot water working in your home. There a number of reasons why your Vokera boiler’s light is flashing red and one of our Gas Safe engineers can help quickly resolve this issue.
If your Vokera boiler is not working it could be due to a variety of causes. This can be anything from a faulty PDB board or pump, or even an issue with the gas supply. If your Vokera boiler is not working get in touch with us right away and we’ll arrange for an engineer to visit and repair it.
Absolutely brilliant service by Homecure. We have had an ongoing issue with our troublesome boiler for a few months now. We have had several companies in over that time but no one had seemed to solve the issue with many people advising to change the boiler even though it wasn’t even 10 years old. We thought we would give Homecure a try after a family friend had recommended them and all I can say is they were fantastic. The engineer who came (I think his name was James) was able to find out what the issue was within 30 minutes, he also explained why it was most likely the other engineers didn’t find the issue. I can only put this down to some serious expertise on his part. A new part was ordered and a return visit booked for the next day and everything was restored and working perfectly again. The prices were definitely reasonable for the experience and expert knowledge received, I would say you definitely get what you pay for. I only wish I found Homecure Plumbing earlier. Needless to say I would highly recommend and will definitely be using again. Regards David H
