Most common fault codes

Code	Severity	Plain English	DIY
B4	Low	Your boiler is currently running at its lower power setting to maintain temperature efficiently.	Yes
B5	Low	Your boiler is currently working at its maximum power setting to meet a high demand for heating or hot water, which is a normal operational signal rather than a malfunction.	Yes
S3	High	Your boiler's burner has shut itself down for safety because it failed to light or stay lit correctly.	Yes
VA	High	Your boiler has detected an internal system error and has locked itself out as a safety precaution.	Engineer
VA-TS	High	Your boiler has shut down because it has detected that it is getting too hot, triggering a safety switch to prevent damage.	Yes

Parts for discontinued models can be hard to find and expensive. A new A-rated boiler could save you money on both repairs and energy bills.
