SeeLevel II Tank Monitor problem
Our 2014 25FB SeeLevel II tank monitor started showing an “err” message for fresh water and sometimes an “opn” message. Garnet tech support ran me through some diagnostics and said my sender was probably in need of replacement. Then it started working properly again. Then I started getting error messages again
Today, the freshwater is working properly and the gray and black tank are both showing “err” messages. Since the company is closed this weekend, I thought I would put this question out to see if anyone has overcome this problem.
