Plot hole: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a compacted cube.

Other: In the life pod scene, GO-4 puts the plant in the middle of the pod. Just before this Wall-E and Eve peer around to see it doing so. If you look very quickly at Eve's back when the camera pans around, you can see two different textures flick on and off. This must be an animation error.

Continuity: When EVE is reactivated on the Axiom bridge, she 'sits up' on her transport bed. The camera shot changes and she's 'standing' well in front of the bed rather than on it or even right next to it.

Continuity: After the escape pod scene (but before the 'dance'), Wall-E uses a fire extinguisher to fly back and forth. Between every camera shot except one, all the extinguisher particles disappear instantly.

Continuity: Wall-E's city has total cloud cover with only the very occasional, and relatively small, opening. It's mostly dust, not water vapor, given its brown color. Since dust exists all over the world it's pretty much a certainty that this sort of cloud cover is present everywhere on Earth. Yet, when the planet is viewed from space, no such cloud cover is visible anywhere on the planet. Not even over Wall-E's home turf - at the start we see a shot of the USA, clearly visible from space, then we zoom through thick cloud cover that's appeared from nowhere.

Continuity: When Eve repairs Wall-E, you can see some tread segments are popped out, but when Wall-E powers back up they're all good as new. She doesn't replace his treads, just some gears.

Continuity: In the scene where Eve meets the cockroach and Wall-E, after blowing up the tires Eve approaches Wall-E. We get a shot from Wall-E looking down Eve's gun, and her eyes are squinted and challenging. The shot changes to the side so the cockroach can jump to Wall-E, and her eyes are softer and more neutral- then the shot changes back to looking down the gun and they're challenging again.

Continuity: After Eve pops the bubble-wrap, she drops it to the floor, yet when the camera pulls back for Wall-E to dance, the wrap is gone.

Continuity: When Wall-e is climbing the ladder on the space ship, he climbs nearly to the top. Then he is knocked down from the force of the take-off. Then in the next shot, he is back at the top.

Deliberate "mistake": When Eve repairs Wall-E, she uses a jack to push him back into shape, putting it in one side, and separating it. Then she slides it to the other side. The jack collapses instantly as she slides it; if jacks collapsed that easily they wouldn't be very useful. The sort of jack she uses doesn't have a release mechanism either.

Continuity: When Wall-E first sorts his goodies, he puts the Rubik's Cube on the left-hand shelves, same as the lighters and spork. Later when he shows Eve the Cube, he pulls it off the right-hand shelves from behind the camera.

Continuity: When Eve fires a shot at the tanker they show an overhead view of the scene - there are three other tankers sitting on the starboard side of the exploded tanker. When the tankers fall like dominoes there are now four of them next to the exploded tanker.

Continuity: When Wall-E shows the plant to Eve for the first time, Wall-E is facing her front on. When Eve replays the same scene in the Captain's quarters, the position of Wall-E is different. He has shown positioned at a different angle.

Continuity: The ramp to Wall-E's home has got ridged slots, however, in some shots the slope is completely smooth.

Continuity: When EVE leaves the line-up and is followed by Wall-E, he does not leave a dirt path, though before and after this scene he does.

Factual error: When Wall-E plays a video tape of the movie "Hello Dolly" the image on the screen is very clear. Video tape is a magnetic medium that will degrade over the years. After 50 years, the picture would be almost unviewable; Wall-E is watching a tape that is over 800 years old. Could he have been making new copies? Same problem - after making copies of copies for 800 years, the picture would have been unviewable.
