About FaultDecode

When an AC, washing machine or inverter shows a code like E5, CH05 or 4C, most people have no idea what it means. The manual is lost, and search results are full of copied lists that disagree with each other.

FaultDecode explains each code in plain English, with a short Hindi section on every page. For each code we tell you what it means, what you can safely check yourself, and when you need a technician.

Who it is for

• Home owners in India with AC, washing machine, inverter and kitchen appliances from Indian and global brands.
• Technicians and shop owners who want a quick reference.
• Plant and maintenance staff looking up drive (VFD) fault codes.

What we do not do

• We do not guess. If we cannot find the brand's own explanation of a code, we do not publish a page for it.
• We do not show repair prices until we have real quotes from technicians.
• We never ask you to open sealed electrical, gas or refrigerant parts yourself.

FaultDecode is independent and not affiliated with any appliance brand. Brand names are used only to identify the products the codes belong to.
