# Repairing a Cat Mate C500 automatic pet feeder We have one of these: [[Cat Mate C500 automatic pet feeder]] It started going into an infinite spin. (Which drove [[Enid]] a bit mad!) Thanks to this very helpful video [Fixing Cat Mate / Closer Pets Automatic Feeder (Infinite Spinning)](https://www.youtube.com/watch?v=EYNqHgT_C-U), I learned that usually all you need to do is clean the sensor. I did, and it worked fine again. Handy tip also about holding ADJ + UP to make it spin to test it, and to realign it if it's gotten misaligned.
