How ErrorKhoj helps

When an AC, washing machine or fridge stops working, it shows a short code such as E6, CH05 or 4C on its display. Every brand uses its own list, so the same code can mean something different on LG, Voltas or Samsung.

ErrorKhoj explains 406 codes from 13 brands. For each code you get the meaning in plain words, the usual causes, safe steps to try at home before calling a technician, and the source the meaning comes from.
