Hello- we are staying a friend's cabin and the alarm on top of the circuit box for their grinder pump went off. I don't want to call the owner to bother them and I am trying to troubleshoot the alarm.

The circuit box outside is a hydromatic but not sure of the actual pump specs. The documentation inside the box didn't provide any clue. I did cycle the circuit to see if I could reset the alarm but when I powered back on the alarm was still going. Looking online, it appears the alarm may be a high water level issue or perhaps a bad alarm switch but I cannot find any troubleshooting documentation online.

Anyone have suggestions for how I should proceed? Thanks much!
