Chosen Solution
I have the black Petcube bites. The wheel is spinning to drop treats into the launching compartment but the little paddle that launches the treats out is not moving at all. It sounds like a gear keeps spinning and then just stops. There is no treats stuck behind the flinger from the bottom trap door. I am using the recommended Blue Buffalo Blue bits dog treats.
I had the exact same problem with mine, and once again, I was out of warranty. I thought there was no harm in investigating it myself, as it wasnt flinging anyway. The base of the unit has a rubber mat that is glued to the aluminium case. Carefully remove this by peeling it off the base, ensuring that bit comes off cleanlyYou will find there are about 6 screws holding the base on. Using a Philips screwdriver, remove them.Next you will need to remove the camera and chute from the front of the unit. It is simply attached to the motherboard inside by a plug. So gently prise this off with as little force as possibleThe internal of the unit should now easily pull out of the aluminium caseThere are about 8 screws holding the internal unit together. Carefully remove those with a Philips screwdriver and pull the two halves apart. Making sure that you don’t damage any of the small cables attached to the different sides. You will now have access to the motors and the cogs which turn the dispenser and also load the tension on the catapult itself. It appears that mine had jammed, and if you move the parts gently, you should be able to free the jam up. All in all, it took me about an hour to complete the job and put it back together, and I now have a fully working Petcube Bites once again. Hope this helps someone in the future looking to do the same with an Out Of Warranty device.
There just doesn’t seem to be any information on repairing these yet so I would contact them directly here: https://petcube.com/support/
Just missed the 1 year warranty, they won’t look into it looking for instructions to open the whole thing
