Some of the lights on the back-box appear to be out.
One of the flipper-looking plastic pieces on the playfield is loose and the ball can get stuck.
We should also test that each bumper works when the ball makes contact
Metal deformation in the wheel stopper hole of the score assembly. This causes the machine to hit max score, rather than zero score, on reset.
Spare backbox has this problem even worse.
Scores are wrong on startup, with baseline being 40000. It is possible the spider arm was reinstalled in the wrong position after disassembly for cleaning.
Special hole not sensing or ejecting.
We had this problem once before and it turned out to be score wheel related but now I am not so sure
Score wheel was overwound and would not always increment. After winding to the standard 3 turns the reset is slow and sticky. This wheel also needs to be removed and cleaned.
