Hi there, my litter robot yesterday kept flashing blue after every cycle even though the bag had been changed, but today when I press the reset button it constantly flashes fast on the yellow light, and does nothing, it won’t cycle, I’ve taken it apart, washed it all and left it unplugged for awhile but just turned it back in and it’s still doing the same thing, I purchased my litter robot from you but can’t remember how long ago… please help!!!
