Z21 switch panel issues

2019 Nitro Z21 all pumps and bilge quit working on the switch panel, anchor lights, horn and fan continued to work. Replaced switch panel and the pumps still don't work, but not the anchor light button on the panel is flashing about every 10 seconds. Checked all the fuses in the panel and connections I could find and none of the pumps are working.

Possibly all your pump grounds are wired together ? That's the first thing I would check. On my boat they are all wired together.
