Litter Robot 3 Pinch Detect (permanent) Error (rapid blink yellow light) Bypass/Fix. See note first!

BEFORE DOING THIS BYPASS HACK:
Be sure to do the usual fixes first.. Clean plastic pinch detector part that flexes first (the cracks), then clean both sides of clear screen covers over drawer full lasers, and the laser part too. Look at the metal pieces for the detector that touch and make sure they are clean, not corroded and actually touching. If doing these fixes fixes your problem and yellow rapid light stops. Then you know this was the issue, and this bypass will work for you if you want a permanent solution that you don’t have to repeatedly check and clean to fix this ever present reoccurring error. If these fixes don’t work for you, then you may need a new DFI (drawer full indicator) or chip board replacement.

Helpful video to get you to the pinch detector terminal spot inside the robot where I apply my fix if you don’t know how to get there already:

(Left this out of video):
You take the bottom off by removing I believe a total of 9 screws, some you will need a long screwdriver to reach. I didn’t put this in my video as it was too hard to hold camera and remove screws, but I wish I’d pointed them out at least. Sorry for that. When you flip the base over, remove screws at the feet pads (spots robot sits on- quarter sized circles), you will see a long tunnel at the sides of these pads (3 of them, the 4th is shorter screw closer to surface) the long tunnels have a screw at the bottom to remove. A long magnetic screw driver is helpful as putting them back in without one can be a challenge, but you can also attach a magnet to the metal of your long screwdriver and this will help. There are 2 screws under each handle and one at the back side of the robot in the center. I believe these are all you need to take out to remove base, just keep track of what you’ve removed and from where. If you look up videos for pinch detector replacement that should walk you through the base removal too. Truly you should not try this bypass unless you have previously checked your metal detectors to see that they are touching (not even smallest gap), they are clean, & they don’t have corrosion, also make sure the moveable trip sensor plastic piece inside robot litter emptying square shoot doesn’t have debri on it or stuck in crack. When you fix all these issues, and robot functions as it should without error, Then you know there is no problem with your circuit board or a wire connection or wire problem. These may need replacing to fix. If everything functions and you are just sick of having to check all these things and clean everything again and again to return stop yellow light error, then do the bypass and you’ll never have to mess with any of the above again. But it’s important to know that cleaning, and fixing the contacts of your trip sensors fixes your issue before you do this permanent fix. Hope this helps :)
Maybe one day I’ll take my robots apart again and shoot a better video, but I’ve had no issues since my fix and just had no desire to do another video detailing it again in even more depth. Maybe some day :)
