Frequently Asked Questions - Vaillant Appliance Repair St David's
What is checked during a Vaillant heat pump service?
A Vaillant heat pump service includes a rigorous 28-point check covering visual inspection of the system, temperature and performance testing, pipework and pressure checks, leak detection, and electrical circuit testing. The engineer also provides professional advice on system setup and use.
How long does a Vaillant boiler service take?
A thorough Vaillant boiler service typically takes between 30 minutes and one hour, depending on the boiler type and whether any faults are discovered during the inspection.
Why does my Vaillant boiler keep switching off?
Common causes include trapped air in the system, low water pressure, a faulty thermostat, or debris buildup in components. First check the pressure gauge and repressurise if below 1 bar. Then check thermostat settings and batteries if wireless. Bleed radiators if you suspect trapped air.
Are Vaillant heat pumps noisy?
No, modern Vaillant heat pumps operate at similar noise levels to a standard household appliance. The aroTHERM Plus achieves sound power levels as low as 48dB(A) at three metres distance, and some models carry Quiet Mark certification for their low noise output.
What do F28 and F29 fault codes mean on a Vaillant boiler?
F28 indicates ignition failure, meaning the flame signal was not detected during the ignition phase. F29 means the flame was lost during operation and reignition was unsuccessful. In cold weather, a frozen condensate pipe is the most common cause. Check the external white plastic pipe for ice and thaw with warm water.
