My horror mansion has a tendency to stop paying out regularly. It seems to 'jam' after 150 balls or so.
I don't really see a jam of any kind, it just stops paying. On the pack 1 of the leds is on. The 払い出し中表示 Payout due indicator, but I guess that's just to say it aint done yet.

If i then nudge the machine (or hit it) it continues paying out for another few hundred balls, stops again, and the whole process has to be repeated.

Does anyone have an idea what i could check ?
