Several weeks ago, we got our first TT, a new Rockwood 8293IKRBS. We took notes of everything Camping World told us during orientation and followed their instructions exactly when we took our shakedown weekend last week. They missed something critical!
After hooking up I checked and we had running water from both the hot and cold faucets so I turned on the electric hot water heater. We had no hot water! A few kind soles in the campground were trying to help me figure out what was wrong when one gent mentioned the hot water heater bypass but no one could locate it.
Once we got home and I started reading this forum, I saw comments saying if you try to use the electric hot water heater without turning off the bypass, you will burn out the element within minutes and that it is an expensive repair that will probably not be covered under warranty. I was in a sate of panic!
Luckily my buddy (also a camper) stopped by yesterday to help me and we found that to get to the hot water heater, you have to go in under the bathroom sink where the cabinet door is screwed shut and you need to reach out the side of the cabinet and turn 3 separate water valves in order to get water flowing into the heater (you need small skinny hands to do this). Once we knew water was running to the heater, I turned on the electric and within a short time I had hot water. Even though I had initially turned on the electric function for some time, for some reason I was fortunate and avoided disaster. By the way, Camping world said between their service backlog, needing the manufacturers authorization if it was warranty and ordering the parts, I was looking at a 6 - 8 week wait for the repair. Thankfully there is no issue now as we are less than 3 weeks away from our first weeklong trip to the beach.
Anyway, to make a long story short, if you are given an orientation of a new unit and they do not talk about the bypass, ask them and make them show you where the valves are and what position they should be in. The owners manual does mention the bypass but does not tell you where it is located.
Enjoy your new camper.
