Quoted from JustLikeMe:Have a bit of a problem - when I switch the machine on the cellar kick out coil fires repeatedly and then this alert appears:

If I start a game the back door shot triggers repeatedly with the ball in the shooter lane. I’ve checked the connections under the playfield and nothing appears to be loose, so I’m guessing it may be an opto issue.
Before I remove the house to get to the opto, can anyone point me in the direction of a replacement opto set? If they do need replacing I’d rather have them to hand.
This is the exact issue I had with the EHOH I borrowed from Electric Circus.
When entering the back door the ball would break the light beam thus triggering the coil to fire but the ball wasn't then rolling as far as the kicker - coil continues to fire - operator error.
I took the plate off under the playfield (no need to touch the house at all) and discovered that the welds on the plate were so badly finished they were causing the hangups. I filed down the plate and the ball rolled through fine - unfortunately I didn't remove the board with the opto on and filed that off - Doh.
I got a replacement from Stern Store EU (#520-8039-00) for 10.47 (+25.21 P&P).
That MAY be your problem.
It could be that the opto has failed altogether, or just needs cleaning, or that the machine isn't perfectly level at the rear - EHOH appears particularly sensitive to levelling left to right.
