Do not stop at the definition

A code is evidence of a condition detected by the appliance. The useful question is what should be checked next. Where the approved source material supports it, TradeAssistIQ can provide causes, diagnostic steps, expected values, component checks and relevant technical information.

Search accurately

Include the model or range when you know it. That small detail can prevent a fault code or technical value from being applied to the wrong appliance family.
