Suburban On Demand Hot Water Heater Not Lighting on Basecamp 20X
Hi all,
I have a 2022 Basecamp 20X that I'm having issues getting any hot water. I wanted to float the problem out there to see if anyone else had a similar experience or knows of a fix. It has a Suburban tankless water heater.
With the pump on, a full water tank, gas on, and the water heater turned on, I can hear the water heater ignitor attempting to click repeatedly, but it only blows cold air out the exhaust outside and no hot water. I"ve randomly gotten it to get hot water maybe two times over the last 4 months with probably 30 tanks of water testing it. I even brought it to the dealer and they got it to work on the first time randomly without doing anything different than me. They told me that sometimes I need to run the water starting with the outdoor shower, then the low drains, then the kitchen sink, then the shower to rid the lines of any air. Then I shouldn't have a problem. But, still not working. The problem is the same when I hook up to city water as well.
My guess was a bad ignitor or it's not getting gas. My heat works though perfectly and ignites. It's my understanding that the furnance and the hot water heater are the same unit so this confuses me that one works and the other doesn't. I've also turned on the kitchen burners beforehand to help get the gas through the system more.
Hoping someone can chime in on this. Thanks!!
