Just need to know what the boiler code means? Start there.
You should not have to spend ten minutes finding the correct manual just to establish what the appliance is reporting.
Choose the manufacturer, include the model when you know it, and enter the fault code exactly as it appears. If you need to go beyond the definition, TradeAssistIQ can take you into the available diagnostic information.
Why the model matters
F1, E1, E133 and other codes are not universal engineering language. The same characters can mean very different things on different appliances. TradeAssistIQ keeps the manufacturer and appliance identity in the search rather than assuming the code means the same thing everywhere.
