No depth readings from Simrad GoXSE. Barnacles?

[Tommy DL]

I have a Simrad Go XSE, SeaRay 19” SPX 190 2021 brand new with Simrad already installed a year ago when I bought the boat, and the depth finder has been working fine all year until last 2 days. I keep my SeaRay in a high n dry usually. I kept it in the water in my slip behind my condo the last 7 days and noticed some small barnacle growth over the bottom and some barnacles on the transducer which is mounted in the bottom center of the hull. Could the barnacles on the transducer be the issue as to why I’m now not getting any depth readings? I was getting depth readings intermittently while moving and then nothing at all. I am getting temperature readings.Thanks for any help provided.
