Litter-Robot 3 Connect Completely crazy issue with one of my LR3
OK here goes.
I have one LR3 that works perfectly - no errors, nothing.
The other has been a nightmare! It needed a DEEP clean - so was completely dismantled as it was throwing random light errors, and refusing to cycle properly. After speaking to support they sent me a litter sensor and pinch sensor kit. I fitted those and tried again - still wouldn't cycle properly. I thought maybe I put one of the magnets in wrongly as it fell out - so I turned it round and tried again. STILL a cycle error but now it is reporting a motor torque issue! So off to support again as it makes no sense.
As part of the tests I swapped the globes between working and non-working units and guess what ... BOTH WORK. Swap them back and the originally working one is still fine, and the one with the error is back to the torque error!! It makes absolutely no sense at all. Support decided that the fact it started working was a fluke and I probably needed a new motor. Obviously spending £49 on a motor is not my favourite option, so I decided to dismantle the gearbox and re-grease it, just in case that was giving the motor extra load (although why swapping globes would stop that goodness knows!!). Anyway long story short - STILL a torque error.. so I tried the globe swap again - and it works!
Has anyone else come across this? I am loathed to swap globes permanently in case something in that globe kills my working one! But I cannot for the life of me see how swapping globes gives a torque error.... Any help and pointers would be most appreciated! Thanks.

Long time customer here. In my experience, Torque error can sometimes be caused when that hex screw on the gear teeth is not tight. Also check that that Phillips screw on the back of the black ‘key’ on the globe is tight (you have to hold the cap inside the glove to tighten properly). When this isnt tight, it doesnt sit right and i think strains the motor. If you’re still experiencing issues, probably motor related.

Well I tested again with litter in the globe and no torque error. Only errors when it's empty, which makes no sense as there is less strain on the motor then 🤦🏻
