The cycle does pause at the dump, for the usual amount of time (1 – 2 seconds), but then rather than rotate in the opposite direction (clockwise direction), it then continues to rotate anti-clockwise.
This will only last 1 – 2 seconds before stopping again, and then the yellow light begins to blink continuously (before this the yellow light is in its usual solid on ‘in progress’ state).
At this stage the Cycle, Empty, and Reset buttons have no effect. I then press the power button (just one single press), and I then see a rapid sequence of blue, then yellow, then red light, before the yellow light remains on as the globe continues to rotate in an anti-clockwise direction (this causes the guard / key spring to make a loud crack / popping sound).
This will continue to rotate all the way around (full 360) until it reaches the dump, and the above process is repeated as described, above.
Ive replaced pinch sensors and the IR waste sensors a couple of months ago.
