Truma AquaGo water heaters have been around for quite a while now, but our Winnebago EKKO is our first RV with one.  We didn’t know what we were missing!  If you’re used to waiting for your water heater to “heat up”, the AquaGo is a game changer.

But over time, the calcium and other minerals in your RV’s water can collect inside the AquaGo, and you need to get rid of that gunk.  It’s really pretty easy with the AquaGo, because they designed a way to do it right into the water heater.  You won’t be mixing up a home-brew vinegar solution to run through your RV’s plumbing.  Instead, you’ll use Truma’s de-calcification tablets.

When it was time to run through the process on our EKKO, I did what many people probably do: surf through YouTube to find someone showing me how to do it.  And I found lots of videos on the process.  But there was one problem:  All of these videos show the process using the single-unit AquaGo control panel… which we don’t have.  If you have more than one Truma appliance in your RV, you likely have the CP-Plus control panel like we do.  So I had to figure out the process with the CP-Plus.  (Well, I didn’t actually figure it out all on my own, I asked Truma.)  The result is this video.



There’s really only a few things you need to run through the process:

Once you have all those, you can follow along with the video.  Start to finish, it will take you about 3 hours.

A Few Final Notes

Prior to running the rinse cycle, it would have been better if I had removed the aerators and strainers from faucets, and also removed the showerhead.  The reason why is that if the clean cycle dislodges any sediment or debris, you don’t want to trap that inside your plumbing fixtures behind a screen or filter.  I did check them afterwards, but it would have been better to do it during the process.

Also – after the rinse cycle, Truma recommends that you drain your hot water system and check the Truma filter for debris before resuming normal operation.  Since I was going to sanitize my entire water system afterwards anyway, I didn’t do this specifically.  I wind up draining and removing the filter a number of times during my sanitizing procedure, so trust me – I got it done.  But if you’re not going to sanitize, then do be sure to drain it and check for debris one last time before getting back to normal.

And there you have it!  Any comments or questions, sound off below.  (But if the questions are super-technical, I may pass you off to Truma!)
