Vokera is a popular boiler manufacturer that produces high-efficiency combi, system and open vent boilers that won’t break the bank. The brand has an extensive product range and each boiler boasts the latest technology to minimise the risk of problems and breakdowns. But, like any well-made boiler or appliance, this doesn’t mean that your Vokera boiler won’t develop a fault and need a repair every now and then. Some problems can be simple to fix and you may even be able to deal with them yourself but the majority of issues will require a Gas Safe registered engineer to inspect your boiler and carry out the necessary repairs.
We’ve compiled a list of the most common Vokera Boiler Problems and what you need to do next to ensure your boiler is safe to use.
1. Water isn’t getting hot enough
If you’ve owned your Vokera boiler for a while and your water isn’t getting hot, chances are high that the culprit is a faulty diverter valve. The diverter valves on Vokera boilers are prone to failing or getting stuck, leading the water to go to only your radiators and not your taps. However, it could be something as simple as your hot water not being set to the right temperature.
What to do next: Check your boiler settings to see if anyone has changed the hot water temperature. Sometimes a power cut can reset your boiler and affect your boiler settings, so you may just need to adjust the timer. If the settings are fine, you’ll need to call in a Gas Safe registered engineer to see if a stuck or faulty diverter valve is the cause of your hot water problems.
2. Boiler is not igniting
There are many possible reasons why your Vokera boiler is not firing up, such as a non-functioning gas valve, faulty ignition leads, blocked flue or, worst of all, an issue with the printed circuit board (PCB). A PCB can set you back hundreds of pounds if it needs to be replaced, so fingers for you crossed that it isn’t the printed circuit board.
What to do next: It might not be any of the above and, fortunately, there are a few simple checks you can make before contacting a qualified engineer. If you’ve had a power cut recently, the timer on your boiler may have reset, so take a look there first. Then, check some of your other gas appliances to see if their working to eliminate an issue with your gas supply. You’ll need to call your gas supplier if you find that there’s a problem with the gas supply to your home. Also, check that the boiler pressure is correct. If your Vokera boiler still fails to ignite after trying these simple fixes, you’ll have to get a Gas Safe registered engineer to look at your boiler.
3. No hot water and no heating
If you’ve woken up to find that you are without both heating and hot water, it’s likely that a frozen condensate is to blame. When the condensate pipe runs outside, the water inside of it can freeze, blocking the pipe and leaving you with a non-working boiler.
What to do next: Turn your boiler off and go outside to look for the pipe (it should come out from the same wall that your boiler has been mounted on) to see if it’s frozen. If it is, you can thaw the ice blockage by pouring some warm water onto the pipe or by placing a hot water bottle onto it. Don’t be tempted to use boiling water as this is dangerous and can damage the pipe. Once the blockage has been cleared, go back inside and switch on your boiler to see if you have heating and hot water again. You might need to re-pressurise your Vokera boiler after turning it back on (see your boiler manual for instructions). If you can’t locate the pipe, the pipe is dangerous to get to, or you still have problems after melting away the ice, then you must get in touch with a Gas Safe registered engineer.
4. Boiler pressure is too low
As a general rule, your boiler pressure should be between 1 and 2 bar, but your boiler manual will be able to tell you the correct pressure level for your Vokera boiler. If the pressure gauge on your boiler is showing below 1 bar, then it’s definitely too low. Low boiler pressure can often be an indication that there a leak coming from your boiler, the pipe or a radiator. Bleeding your radiators can also cause the pressure to drop.
What to do next: If you’ve bled your radiators recently, you can re-pressurise your Vokera boiler without needing to call in a professional. Your boiler manual will include instructions on how to re-pressure your boiler, but be sure to contact an engineer to do it for you if you’d rather not attempt to do this yourself. Not bled your radiators lately? Then have a look at your boiler, any pipework and your radiators to see if you can spot a leak. If you find a leak or you haven’t bled your radiators recently and you can’t locate a leak, turn off your boiler and call a Gas Safe registered engineer.
