Re: Water temp/Level Red LED

["dalewitt" <dalewitt@express-news.net>]

I have had this problem on both my roccos.  In both cases, it was leakage from the overflow tank that allowed moisture
around the sensor/connection.  Dry the connector and around the sensor and see if problem stops.  If this is not the cause
you may have a short in the ground
