Error codes of Daikin air conditioners

Daikin brand air conditioners are one of the most popular on the market. They can boast of rich functionality, modern appearance and durability.

But do not forget that the split system consists of many components that can fail during operation. When a particular component stops working correctly, the air conditioner reports this by displaying the so-called error code on the display. It can be decrypted and thus find out what happened to the device.

This article presents all the main error codes of the Daikin air conditioner. Every user should know about them. If one of the errors occurs, contact the service center for help. Do not attempt to perform repairs yourself.

We have divided the article into several parts. You will learn about errors that occur in the operation of both the outdoor and indoor (wall) units. You will also learn about common malfunctions.
