Common Vaillant Fault Codes

F.75 points to the pump or pressure sensor not registering a change in pressure. F.28 is a failed ignition, often the gas supply or the spark electrode. F.22 means low water pressure. The code tells us where to look. Testing tells us what has actually failed.

Accredited Installer Benefits

Being an accredited Vaillant installer means longer registered warranties on the boilers we fit and ready access to genuine parts. Genuine parts matter on a Vaillant, because pattern parts often fail sooner and can affect a warranty claim later on. We record every repair we carry out.

Looking After a Vaillant

Vaillant boilers last well when they are serviced every year and the system water is kept clean. A magnetic filter and the right level of inhibitor protect the heat exchanger, which is the expensive part. Insulating the condensate pipe stops it freezing in winter.

Frequently Asked Questions

What does fault code F.75 mean on a Vaillant boiler?

F.75 usually means the boiler cannot detect a pressure change when the pump starts. The cause is often a failed pressure sensor, an airlocked pump or a blocked expansion vessel, and it stops the boiler firing. It is a common repair and we carry the parts for it.

Do you repair Vaillant boilers in Godalming the same day?

Usually. We aim to be with you within two hours and hold the Vaillant parts that fail most often. Around nine in ten repairs are completed on the first visit. If a less common part is needed, we order it and confirm the fitting date before we leave.

Will a repair affect my Vaillant warranty in Godalming?

Not if the work is done by a Gas Safe registered engineer using genuine parts and recorded properly. As an accredited Vaillant installer we fit genuine parts and log the work. Keeping the annual service up to date is the other condition most warranties require.
