About ErrFixHub

ErrFixHub.com is a free, independent reference library dedicated to explaining the error codes displayed by home appliances — air conditioners, washing machines, refrigerators, microwaves, geysers, inverters, solar inverters, water purifiers, and dishwashers.

When your appliance flashes a cryptic code on its display, our mission is straightforward: tell you exactly what it means, explain why it happened, and guide you through the safest steps to fix it.

Our Story

ErrFixHub was founded in 2026 by REZAUL Karim (Riad), a certified electronics repair professional based in Dhaka, Bangladesh, with over a decade of hands-on experience in consumer electronics diagnostics, mobile technology, and appliance servicing.

After years of seeing homeowners struggle with confusing error codes and unreliable online information, Riad created ErrFixHub to provide verified, manufacturer-referenced troubleshooting guides that anyone can follow — from first-time AC owners to experienced technicians.
