Customer support for a phenomenon in which Error 70 or Error 80 occurs repeatedly on the EOS 70D Digital SLR Camera

Updated on: 30th June 2022
Revised on: 30th May 2018

30th June 2022: Information concerning discontinuation of free repairs has been added.

Free repairs for this phenomenon will be available for eligible cameras until 31 December 2022.

Thank you for using Canon products.

We would like to offer our sincere apologies to users who have been inconvenienced by the phenomenon described below.


In rare cases, error 70*1 or error 80*1 may repeatedly display on some EOS 70D digital SLR cameras due to an internal communication failure resulting from the structure of the electrical printed circuit board. If use of the camera is subsequently continued, a state may occur in which the camera’s power does not turn on. In most cases, this phenomenon occurs in conjunction with continuous use of the camera while the camera’s internal temperature is high, such as when shooting movies continuously.
“Err 70” or “Err 80” will appear on the LCD monitor at the back of the camera or on the LCD panel at the top of the camera.

*1 There may be rare occurrences of error 70 or error 80, after which the camera functions can be recovered by turning the power off and on again, or by removing and reinserting the battery. The phenomenon described here refers to the frequent reoccurrence of error 70 or error 80.

Possibly Affected Cameras

Only some EOS 70D digital SLR cameras are affected by this phenomenon.

The phenomenon may occur only in cameras whose first two digits in its serial number are within the range of “00” to “22”.
