My first post, so be gentle!
We took our brand new 2021 BC to a local campground for a break in last night. Full hookup. Everything worked as expected until shower time. The Truma water temp icon no longer was flashing so we assumed all was good. There was continuous hot water in the kitchen sink. However, the hot water in the shower lasted about 10 seconds and then returned to tepid/cold and stayed there. Needless to say, last night showers were very quick! We tested again this morning with the same results. Any thoughts are appreciated.
