Litter Robot 3 Open Air flashing blue and yellow lights

Hi!

Our Litter Robot 3 Open Air had been flashing blue lights constantly even after the draw was cleaned.
And when manually pressed cycle, it cycled and then started flashing blue light again.
However, since this morning, the cycle button stopped responding and when reset button is pressed the yellow light flashes really fast until reset button is pressed again.

This is what happens in sequence…
Turn on -> flashing blue -> reset button -> fast flashing yellow light -> reset button -> flashing blue light.

We disassembled and cleaned all parts and it still doesn’t make any difference.
It doesn’t look like the anti pinching pins as we cleaned those as well and they are firmly touching.

What else can I do to fix this?

Thank you so much in advance for your help!
