Again not positive but just thinking about how MS got this scheme to work... there must be one or more relays that trigger alarm & pumps.
One for alarm on loss of pump power must be normally closed with power opening it. When pump loses power contacts close for the alarm. If that relay wire is off / loose / broken it would trigger the alarm even with power still to the pump.
Tracing wires to find relay(s) might identify the problem area.
