Boiler fault diagnosis without the manual hunt
A fault code is useful. Knowing what to do with it is what gets the appliance diagnosed.
TradeAssistIQ is built to help heating engineers get from the code or symptom in front of them to the technical information that matters, without spending the call-out jumping between PDFs and search results.
Go further than the code
Search by manufacturer, model, fault code or symptom. Where the approved technical knowledge supports it, TradeAssistIQ can surface likely causes, checks, expected values, component tests, wiring information and relevant manufacturer material.
The aim is not to turn every fault into a generic checklist. The appliance identity matters. The manufacturer information matters. The actual fault in front of you matters.
Built for the job in front of you
Use the displayed code when you have one. If there is no code, describe what the appliance is doing. A boiler that will not ignite, loses pressure, overheats or produces no hot water needs a different starting point from a simple error-code definition.
