Vaillant boilers explained

In Shepperton, Frank Finn Plumbing is recognised as a certified Vaillant expert. Our expert technicians often recommend Vaillant boilers for homes when a replacement boiler is required. Being a market leader, Vaillant is one of the better boiler brands to buy. They are built for optimal functionality and come with a remarkable 7-year warranty. The Combi System is the most widely recognised and used boiler in the UK, especially in Shepperton.

This is probably due to the little amount of space they take up and because they have no need for a hot water cylinder or a storage tank.

How do you determine your boiler requires checking?

Listed below are common Fault codes displayed on a boiler system;

boiling

Code F27: This warns of a frozen condensate pipe.

Code F22: This points out a popular boiler fault – low water pressure.

Code F75: This indicates your boilerís sensor is not aware the pump has started running. Itís a common problem seen in older boilers that have had magnetic filters fitted or that havenít been flushed in a while.

Code F28: A broken ignition or no gas supplied to the boiler can cause this error code.

Code F29: This indicates the boiler flame is off.

Odd noises coming from your boiler

Boiler emitting strange noises – Air getting in your boiler system is the usual cause.

Issues with thermostat

Thermostat issues – If your boiler’s thermostat becomes inaccurate or intermittently turns the heating on/off, it might be time to get a new one.

Boiler keeps turning off

Boiler keeps going off – Low water pressure or lack of water flow due to a closed valve, air in the system, or problems with the thermostat or pump are the usual culprits for this fault.

Radiator not getting hot

Radiator won’t get hot – You might find that your radiator isn’t getting hot or that only the bottom section is heating up and this can be caused by sludge or air build-up, or unequal distribution of heat.

No heat or hot water

No hot water or heat – usually caused by a damaged airlock or diaphragm, a thermostat problem, water pressure is low or a motorised valve failure

Boiler leakages

Boiler leakages – Never try fixing a leaking gas boiler if you don’t have the necessary training and qualification, instead, call on a Gas Safe registered technician to look at your dripping boiler.

Blown out pilot light

Pilot light goes off – A broken thermocouple can cause this by stopping the gas supply into the boiler. A draught blowing out the pilot light or accumulated deposit in the compartment for the pilot light can also be a cause.

Falling pressure

Pressure is dropping – If your pressure gauge reads “below 1”, the issue might be caused by either a water leak in the system or the pressure relief valve needing replacing or that the radiators were recently bled.
