E18 indicates a lens jam.
That was a problem on one line of cameras for a period of time.

The cameras involved were the Canon A40 through A95.
The years were 2002 through 2004.

The gearbox for the lens extend/retract motor was fragile.
And it was not well sealed, which let sand infiltrate the gear box.

If you are careful with the cameras and stay off the beach, it works fine.
I have two friends with cameras from that batch and they are still working fine.

Other brands of cameras have suffered from lens jam problems on certain models only, from time to time.
It is an engineering/design problem.
I have not heard of this type of problem on cameras built in the past three years.

There are isolated cases, which are usually caused by the camera being dropped.
