Vokera Boiler Problems and Repair

It’s easy to forget that there’s a boiler in our homes working hard to provide heating and hot water every day. That’s until you get up for work and sleepily step into a freezing cold shower when the realisation hits you like ice cold water to the face, the ever-so faithful boiler you haven’t heard a peep out of has packed in.

This could be the point where chaos descends upon the home and nobody knows exactly what to do but don’t worry, it doesn’t have to be that way. Some common boiler problems can be resolved without even having to call an engineer out but if an engineer is needed, (and if in doubt always get in touch with an engineer) you can get a free boiler repair quote with our service.

Who are Vokera?

Established over 35 years ago, Vokera offer a complete home heating package by manufacturing domestic gas boilers to water heaters to solar thermal collectors. Find out more about Vokera and their full range of boilers on Boiler Guide.

Top 5 Vokera Boiler Problems

  1. Frozen condensate pipe

    To transport the acidic water, caused by waste gas, away from the boiler, there will be a pipe that runs outside into a drain. In the colder months it can be susceptible to freezing.

    You will be able to find tutorials online that guide you through thawing out the condensate pipe with boiling water, but if in doubt contact an engineer.

  2. Failing to ignite

    If your boiler is failing to ignite, you’ll hear your boiler sparking but not then lighting as it should, this will also be displayed as error code A01 on the display. This can happen for a variety of reasons including no voltage to the gas or an issue with the gas valve or solenoid valve.

  3. Low boiler pressure

    If your central heating isn’t functioning properly, it could be because of low boiler pressure. To check the pressure level simply take a look at the built in pressure gauge, if it’s below 1 you may have an issue. Find out more with our guide to low boiler pressure.

  4. No hot water

    If your taps are running cold there are several potential causes, including broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels.When checking for the cause, start by looking at the boiler pressure and thermostat. If neither of these are causing the fault then get in touch with a Gas Safe registered engineer.

  5. Error code A03

    This error code, likely to be accompanied by the image of a bell, means that your boiler’s fan is faulty. If you’ve had your boiler for some period of time then this suggests that it has worn down over time and needs replacing.

Which Boiler Issues Need an Engineer?

If you feel up to the task, some common boiler issues can be resolved yourself without the need for an engineer. Use the table below to identify possible causes of problems and know if you need to be getting in touch with a Gas Safe engineer.

Problem Possible Cause Do you need an engineer?
No heat or hot water Broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels Yes
Leaking and dripping Most common cause is a broken internal component but it will depend where the water is leaking from Yes
Banging, whistling or gurgling noises A common cause is air in the system, alternatively it could be that the water pressure is too low or it’s kettling (see below) Yes
Pilot light goes out Could be a broken thermocouple which is stopping the gas supply Yes
Low pressure Could be a water leak in the system, the pressure relief valve needs replacing or due to recently bleeding radiators No, unless there’s a leak
Frozen condensate pipe Your boiler will often display a fault code or warning notification Yes
Thermostat issues Thermostat may be turned off or not set to the correct settings (time etc.) Consider replacing
Kettling Limescale or sludge building up on the heat exchange Yes
Radiators not getting hot Sludge or air build up in the system or an unequal distribution of heat You will need to bleed the radiators which doesn’t require an engineer unless you don’t feel like carrying out the task yourself.
Boiler keeps switching itself off Could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly Yes

Error Codes

When there’s a fault with your Vokera boiler, it will display either an error symbol or an error code, to help you decipher what these mean, use our list of Vokera error codes.

Should You Replace Your Vokera Boiler Instead?

An old boiler can end up costing you quite a bit in repairs so it can make sense to replace it with a brand new one. If you’re thinking about replacing your boiler, you could be saving up to £305* a year in a detached home. The table below shows how much you could be saving depending on your current boiler rating and property.

House Type G (<70%) F (70-74%) E (74-78%) D (78-82%)
Semi-Detached £200 £140 £120 £120
Detached £305 £210 £180 £180
Detached Bungalow £155 £105 £90 £90
Mid terrace house £175 £120 £105 £105
Mid terrace house £95 £65 £55 £55

Who Should You Choose to Replace a Vokera Boiler?

If you want to go ahead with installing a new boiler in your home, then you need to get an engineer round to do the replacement.

A local engineer you might have spotted around your area, could offer very competitive rates and if you like a personal service then you’ll probably be talking to the same person throughout your communications.

National companies, on the other hand, may be slightly more on the expensive side but you’ll have big brand protection, a huge bonus, and they can provide extra service such as ongoing boiler cover.

Most importantly, ensure that the engineer you want to replace the boiler is Gas Safe registered.

Aim to get quotes from up to 3 engineers to give you the best chance of finding the right deal for you.

Boiler Insurance and Ongoing Cover

If your boiler warranty has expired, then boiler insurance is a possible option. You can take out insurance with your energy supplier but you’re absolutely no obligation to do so. When comparing insurance, the best ones will include an annual service and safety inspection, so keep an eye out for them.

Vokera Boiler Warranty

Vokera boilers come with a 12 month warranty at the very least, with their different models ranging from 2-7 years. We’ve put together a complete guide to Vokera warranties so that you know exactly what to expect.
