Swim Platform Issue

Beneteau Oceanis 411 Baltimore
Last weekend the alarm associated with the swim platform on our 2018 Oceanis 41.1 started going off while under motor. I could not get it to stop so I disconnected a wire to the alarm. After getting back to dock I was able to raise and lower platform without issue. I attempted to plug the wire back into the alarm and inadvertently crossed the wires so that the positive and negative were connected. After this I could not get the platform to drop. I’ve checked the 30A fuse and it’s not blown - wondering what suggestions community might have for a fix or next steps to diagnose. Thanks.
