Litter robot - flashing blue, then flashing yellow


I require your help regarding a problem I’m encountering.

LR3, had it approx 3.5 years. Having a mixture of sometimes flashing blue, sometimes fast flashing yellow.
Have changed the pinch pins.
Have taken apart 3 times to check various bits, following recommendations found here and elsewhere!
Have cleaned the unit.
Spent 3 hours checking and cleaning this morning.
Currently flashing blue, as soon as I sort that it will cycle and go beyond normal rotation, stop, and start fast flashing yellow. (I know this because it has already happened today)
I seem to have exhausted all options I’ve found here and in YT.
Anybody had the same issue and have any new ideas?
Thank you in advance!

Thank you so much in advance for your help!
