Common faults in West Ham
Common Boiler Breakdown Causes
Pressure loss
Low system pressure (below 1 bar) is the most common cause of boiler lockout in London homes. Usually caused by a micro-leak in the system or a failed pressure vessel. Check the gauge and repressurise if between 0.5 and 1 bar — below 0.5 bar, call us.
Diverter valve failure
On combi boilers, the diverter valve switches flow between heating and hot water. When it fails, you get heating but no hot water, or vice versa. Common fault on all major brands after 8–10 years of use.
PCB (circuit board) failure
The PCB controls all boiler functions. PCB failures cause intermittent lockouts, incorrect fault codes and complete failure. Often triggered by power surges or water ingress from a leak inside the boiler casing.
Boiler age and repair decisions: boilers under 10 years old → repair is usually worthwhile. Over 12–15 years with multiple faults → replacement is often more cost-effective. We provide honest advice on repair vs replace at every call-out.
