Mike is right. However the problem relates to the draining and refill, so something has changed. It may be as simple as a check valve that was holding previously, but is not now.
A possible solution would be to put a time delay relay between the VS-SP and the bell. Just a few seconds delay should be satisfactory. You would be introducing a possible reduction in reliability, however.
