we had a simular problem with a customers machine on thursday , does yours also lock the ball in and not return it till the next ball starts ?
check the membrane , we have these on order as of yesterday with our next load of Stern parts , if there is a small break this should be the problem ..
yea guys I am doing some repairs now .. even with 3 full time techs ( plus Damien) I am doing service calls and small fixes
