If your Vaillant EcoTEC Plus boiler is not working properly, our experienced gas engineers can help. From low pressure and fault codes to heating problems and loss of hot water, we provide professional Vaillant EcoTEC Plus repair across London.

The EcoTEC Plus is a popular Vaillant boiler range designed to provide reliable heating and hot water. Like any heating appliance, it can develop faults over time. Getting the problem checked early can help prevent a small fault from becoming a bigger and more costly repair.

Whether your boiler has stopped working, keeps losing pressure or is showing an error code, our qualified gas engineers can diagnose the problem and explain the repair options available.

The Vaillant EcoTEC Plus range includes several models and specifications. While these boilers are designed for dependable performance, components can wear over time and faults can occur.

Common reasons for calling a Vaillant EcoTEC Plus repair engineer include:

• Boiler not turning on
• No heating
• No hot water
• Low boiler pressure
• Boiler repeatedly losing pressure
• Boiler going into lockout
• Vaillant fault codes
• Strange or unusual noises
• Boiler switching off
• Radiators not heating properly
• Water temperature problems
• Leaks or signs of water around the boiler
• Poor or inconsistent heating performance

The cause of a fault is not always obvious. Several different problems can produce similar symptoms, which is why professional diagnosis is important.

Our gas engineers can inspect the boiler, identify the likely cause and recommend a suitable repair.

Your EcoTEC Plus boiler may display a fault code when it detects a problem. These codes can help identify the area that needs attention.

Some common Vaillant fault codes include:

F22 – Low Water Pressure

The F22 fault is commonly linked with low water pressure. A boiler may stop working if the system pressure falls below the required level.

If your boiler repeatedly shows F22, simply restoring the pressure may not solve the underlying problem. There could be a leak or another fault within the heating system.

F28 – Ignition Failure

The F28 fault code indicates an ignition problem. There can be several possible causes, including issues with the gas supply, ignition system or other boiler components.

A qualified gas engineer should diagnose the cause before any repair is carried out.

F29 – Flame Failure

F29 can occur when the boiler loses its flame during operation. The cause may be linked to the gas supply, ignition system, flue or another component.

If this fault keeps returning, professional investigation is recommended.

F75 – Pressure Sensor or Pump-Related Fault

The F75 code can be associated with the boiler's pressure sensor or pump operation. A proper diagnosis is needed to establish which component or system issue is responsible.

If your EcoTEC Plus displays a fault code repeatedly, make a note of the code and contact a qualified professional.

A Vaillant EcoTEC Plus boiler that is running but not heating your home can have several possible causes.

The issue may be related to:

• Boiler controls
• Thermostat settings
• System pressure
• Circulation
• Radiators
• Sensors
• Pumps
• Other heating components

The boiler itself may not always be the source of the problem. A heating system includes several connected components, so an engineer should assess the system as a whole.

If your radiators remain cold or your home is not reaching the desired temperature, arranging a professional inspection can help identify the cause.

A loss of hot water can be particularly inconvenient, especially when the boiler appears to be operating normally.
The cause may depend on your boiler model and heating system. Possible issues can involve controls, sensors, valves, water flow or internal boiler components.
Rather than replacing parts without knowing the cause, a qualified gas engineer can inspect the system and identify the fault.

A Vaillant boiler is a complex gas appliance. Internal components should not be removed or repaired as a DIY job.

Using a suitably qualified gas engineer helps ensure that the boiler is inspected and repaired correctly. The engineer can identify the cause of the fault, fit suitable replacement components where needed and carry out the appropriate checks after the repair.

Always check that the engineer you use is appropriately qualified for the work being carried out.

Not every boiler fault means you need a new boiler.

If your EcoTEC Plus is relatively modern and the problem is caused by a single failed component, repairing the boiler may be the most sensible option.

However, if the boiler is older and has developed repeated or expensive faults, replacement may be worth considering.

An engineer can assess the condition of the appliance and explain whether repair is likely to provide good long-term value.

Factors to consider include:

• Boiler age
• Previous repair history
• Current condition
• Repair cost
• Availability of parts
• Boiler efficiency
• Your household's heating requirements

Getting professional advice can help you make an informed decision.

How do I know if my Vaillant EcoTEC Plus needs repairing?

Common signs include repeated fault codes, low pressure, no heating, no hot water, unusual noises, leaks and frequent shutdowns. If the boiler is not working as expected, a qualified gas engineer can diagnose the problem.

Can I repair my Vaillant EcoTEC Plus myself?

You should not attempt to dismantle or repair a gas boiler yourself. Internal boiler repairs should be carried out by an appropriately qualified professional. You can check basic controls and the information shown on the boiler display, but seek professional help for faults that continue.

Why does my Vaillant EcoTEC Plus keep losing pressure?

Repeated pressure loss may be caused by a leak, expansion vessel problem, pressure relief issue or another fault. If you regularly need to repressurise the boiler, arrange a professional inspection.

What does an F22 fault mean on a Vaillant EcoTEC Plus?

F22 is commonly associated with low water pressure. If the fault keeps returning after the pressure is restored, there may be an underlying issue that needs professional attention.

Should I repair or replace my EcoTEC Plus?

This depends on the boiler's age, condition and repair history. A qualified gas engineer can assess the appliance and help you compare the likely cost of repair with the benefits of replacement.

How often should my Vaillant EcoTEC Plus be serviced?

Regular boiler servicing is recommended to help check the condition and safe operation of the appliance. The exact servicing requirements can depend on the boiler and manufacturer's guidance, so check your documentation and speak to a qualified professional.
