Identify the appliance before interpreting a fault
Photograph the accessible identification label and display without opening the casing. Provide the model, product reference, full fault message and what still works: heating, hot water or neither. Tell us when the fault occurs and whether it followed an interruption or earlier work.

Diagnosis before replacing a component
A code describes a detected condition, not necessarily its root cause. The professional may need to check circulation, sensor readings, electrical supply, wiring, ignition or combustion according to the appliance. Do not bridge a safety device, adjust a gas valve or repeatedly reset a boiler in lockout.
Servicing, repairs and quotations
Routine servicing, statutory inspection and fault repair are different scopes. We explain the proposed work and known costs before additional work. Parts must match the appliance reference; availability may affect the timing. After a repair, the relevant functions and safety conditions are checked.
