Corrected entry: When they are washing Shaun in the "Knit-o-Matic", the light changes from "wash" to "light shave" due to a fault. However, at one point Wallace says "Do something Gromit", and if you look at the console after this the light is back to "wash" again even though it is doing the light shave.

Correction: Time and again in this film and 'A Grand Day Out' and 'The Wrong Trousers' it is demonstrated that Wallace's inventions have a life of their own. Sometimes they work, sometimes they don't, sometimes somewhere in between. This is one of those times.
