OK, i found the rule, it is in section 9, player errors:
"Any player who slam tilts a machine, thereby ending play for all players, will receive a score of zero for that game. The slam tilt is treated as a catastrophic malfunction for any other player(s) who have not completed their game(s) in progress. If a tournament official rules that the slam tilt sensor is not functioning properly, the slam tilt will be treated as a catastrophic malfunction for all players."
Regarding what to do next, section 5 Catastrophic Failures:
"When a catastrophic malfunction occurs, if the scores are able to be recorded, players will be provided the appropriate number of additional ball(s) of play on a new game once the machine has been repaired. If the scores are not retrievable, players will be forced to start their game over. No attempt will be made to estimate scores, or reestablish state, at any time."
