The E18 error is an error message on Canon digital cameras. The E18 error occurs when anything prevents the zoom lens from properly extending or retracting.
The error has become notorious in the Canon user community as it can
completely disable the camera, requiring expensive repairs.
A quick internet search for "E18" + "canon" quickly reveals hundreds of similar complaints.
ConsumerAffairs.com reports that the "lens has a feature called bellows claw, which is a gear that physically extends and retracts the lens. A piece that holds the lens, the barrier plate, is not large enough and can sometimes cause the bellows claw to malfunction, resulting in a stuck lens". The result is a black screen that only contains the error message, E18. Another problem mentioned on the site blames a sticky iris in the lens, caused by grease entering inside from the microphones built into the lens. The buildup freezes up the ability of the lens to open.

SOURCE: what does E18 mean?
Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off. This is caused by dirt in between the telescoping portions of the lens. You can clean this with compressed air, generally. Blow air all around the turret sections of the lens. you can also GENTLY push the lens inward ( have the lens extended and take the battery out... then push inward...)

The E18 error is related to the LENS not able to retract fully. If it is still under warranty, I would advise you bring it to the nearest service center. This is to avoid further damages. Otherwise, you can try a few things below.
There are a couple of things you can do.
1. Turn it on and then off. Spray canned air around the lens.
If trick 1 will not work out, try this.
2. Make sure the battery is fully charged. Turn on the camera and then give it a couple of firm whacks on the side. Make sure nothing is blocking the lens and wait for it to fully retract.
Let me know how it goes.

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.
Use these at own risk as it may further damage the camera.
Firstly , try connecting your ac adapter or usb cable.
Try holding the shutter button while switching on the camera.
Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).
Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.
Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.
Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.
Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.
If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.
