The most likely cause is the pump, as Vaillant ecoTEC boilers were previously fitted with Wilo pumps which have a high failure rate but now come with the much more reliable Grundfos pump.
BRITISH GAS F2 BOILER MANUAL CODE
Fixing the F75 faultįixing the F75 error code needs a Gas Safe registered engineer to find out whether the issue lies with the pump or pressure sensor. A Gas Safe registered engineer is the only person who should diagnose and fix this issue.į75 is a very common fault code on Vaillant ecoTEC boilers and appears when the boiler is unable to detect sufficient pressure as the pump is in operation. Over time, the electrode and ignition leads could wear out, eventually stopping altogether. Defective electrode or ignition leads: Should there be a supply of gas and no blockages in the system, there could be an issue with generating the spark to create the flame.Being outside increases its chances of freezing during the winter months and if it does, the boiler will lockout until the frozen blockage has thawed out. A frozen condensate pipe: The condensate pipe leads acidic waste water away from the boiler, outside and down a drain.If not, check your gas meter and contact your supplier if necessary. No gas supply: Test other gas appliances around your property to see if they’re working.There are many reasons why a Vaillant boiler might fail to ignite:

How to get your Vaillant boiler to ignite To let you know there’s an issue, your boiler will display the F28 fault code. Without that flame the water can’t heat up. When you turn on the central heating or a hot water tap, water passes through a pipe that goes over a flame, which heats the water up. When your Vaillant boiler fails to ignite, it will leave your home without heating and hot water. As well as a leak, other issues could include a faulty pump, broken pump lead or defective pressure sensor. Don’t attempt to fix the leak yourself, always contact a professional.
If you suspect a leak, turn off the water supply to prevent damage. However, you should hire a Gas Safe registered engineer to inspect the boiler and check for any faults.Ī common reason for seeing the F22 error code is a leak somewhere in the system. Low boiler pressure is something you can resolve yourself, in fact, we have a guide to increasing low boiler pressure on Boiler Guide.
Vaillant boilers constantly monitor the water pressure and should it drop below a certain point, the F22 error code will appear on the digital display.Īll boilers will gradually lose pressure over time but if there’s been a sudden drop, it’s a sign that there’s an issue with the unit that needs to be fixed.
