If your Vaillant boiler is showing a fault code on the display, the model has already told us what is wrong. Below are the six codes we see most often in Watford and Rickmansworth.
System pressure has dropped below 0.5 bar. Often caused by a small leak or a recent radiator bleed. Quick top up and leak check.
The boiler cannot detect a pressure rise when the pump kicks in. Usually a sticking pump or a failed sensor. Genuine Vaillant pump fitted same day.
Boiler fails to light. Common causes are a frozen condensate pipe in winter, a faulty gas valve, or a dirty ignition electrode.
The gas valve has failed an internal check. This is a Gas Safe job only. We carry genuine Vaillant valves and fit on the same visit.
Boiler has detected a flow problem inside the heat exchanger. Sometimes a power flush resolves it, sometimes a heat exchanger replacement.
The flow and return temperature gap is too wide. Usually a circulation problem caused by a sticking diverter valve or sludge.

A Vaillant boiler will normally run reliably for 12 to 15 years. Once it crosses that mark, repairs start to outweigh the cost of a new install. Here is how we help homeowners decide.

Real homeowners across Watford and Rickmansworth, real Vaillant jobs, all reviews verifiable on Google.
“Came out the same morning to look at our ecoTEC Plus. Fault code F22, low pressure. Repressurised, found the leak on a radiator valve, fixed and tested. Tidy work, fair price, no upsell. Will use again.”
“Booked Pluto to install a new Vaillant ecoTEC Plus. Pre install survey was thorough, install was clean, paperwork came through that evening. The 10 year warranty was already registered on the Vaillant portal.”
“Annual service on a Vaillant ecoFIT Pure. Friendly engineer, gave me the flue gas reading on paper, walked me through the inhibitor top up. Best service experience I have had on this boiler in five years.”
Ten questions we hear every week from Vaillant owners across Watford and Rickmansworth.
Yes. We are registered with Vaillant directly, which means every installation we complete is logged on the Vaillant portal and your full 10 year manufacturer parts and labour warranty is activated on day one.
A serviced Vaillant boiler typically runs for 12 to 15 years. Annual servicing by a Gas Safe engineer keeps the manufacturer warranty valid and is the single biggest factor in lifespan.
Our fixed price Vaillant installations start at £1,995 plus VAT for an ecoTEC combi supplied and fitted. The final price depends on the model output, the position of the boiler, and any system upgrades such as a magnetic filter or smart thermostat.
A full safety inspection, flue gas analysis, gas tightness test, system pressure test, internal seal check, and a written report sent within 24 hours. The service costs £80 plus VAT and keeps your Vaillant warranty valid.
F22 means low water pressure, normally below 0.5 bar. The cause is usually a small system leak or a recent radiator bleed. Repressurise via the filling loop and call us if the pressure drops again within 24 hours.
F75 indicates the boiler cannot detect a pressure rise when the pump activates. The two common causes are a sticking pump or a failed pressure sensor. Both are same day fixes with genuine Vaillant parts.
No. Your warranty stays valid as long as the engineer is Gas Safe registered and the service is logged in the benchmark book. Using a Vaillant Approved Installer such as Pluto adds the extra reassurance that the work is filed on the Vaillant portal.
For one or two bathrooms, the ecoTEC Plus combi is the most popular choice. For three or more bathrooms or low water pressure, the ecoCOMPACT or a Vaillant system boiler with a separate cylinder works better. We give a free recommendation over the phone if you tell us bedrooms, bathrooms, and current boiler.
