Truma Aqua Go warm not hot

[Wandering Sagebrush]

I tested the Truma yesterday, and only got lukewarm water from it.  
 

I haven’t dug into the manual yet, any ideas?

Is yours part of the recall?  If yes, could your burner element have shifted?  Just throwing it out there as an idea.  Mine is part of the recall and I await replacement burner element and worry about it in the meantime 😮 - hence my first thought.

Had that happen once...the cause was the exterior faucets were  on (but the nozzle off) causing internal mixing of hot/cold water.  

The time I had winterized I forgot to turn off both the hot and cold taps.  

I didn't know they were on because the nozzle was clicked off.  

Once I made sure both hot and cold taps we're OFF, the unit heated right up.

It is part of the recall, but I’m not certain anything shifted.  Fingers crossed!

Craig, I’ll check the faucets, but I wonder if we used hot water too soon.  Checking again this morning.

Just spoke with Truma Support, they suspected decalcification was needed.i did not receive the standard filter when I purchased from the original owner.  To my knowledge the system has never been decalcified.  The tech also mentioned that it could be propane related, but was more inclined to suspect calcification.

[Wandering Sagebrush]

Decalcified the Truma, but it’s good news- bad news.  The water is much warmer, but it’s in low 80s.  The temp is consistent now, so I guess I’ll run the decalc process again.  
 

Almost had a genuine OH SUGARFOOT moment.   I did the flush in the bathroom, forgetting to open the drain.  It had about an inch to go when I remembered to hit the switch 😳

[Wandering Sagebrush]

SOLVED - I think… 

Well, I feel a bit foolish, but the outside shower valves were open.   They didn’t feel like it, but they were.  Turning right (righty, tighty) there was considerable resistance, so I assumed (ass-u-ME) they were closed.  Not the case at all he said blushingly.

Dang I feel foolish!  I believe a good test coming out of winterization, is to try and turn the shower valves on.  If you hit a hard stop, they are on.  A slight wiggle when turning right just may indicate an open valve.

The temps went up to 96° before I turned the water off.

The good news is the Truma is decalcified.  Bad news is I am embarrassed.🙈

Thanks for letting everyone know!

Relax in the knowledge that you are not the first and will not be the last to have this kind of issue.  Certainly, I've been in that boat a bunch of times.

Thanks Bill, I’m just irritated at myself.  But… some good stuff were a result.

The best news is everything works, so embarrassing ones self is a lapel pin we all wear. It is a club of honor.😊

@Wandering Sagebrush

Look at it this way. You have now taught all of us OTT owner's to make sure the shower water knobs are completely shut off.

Thanks for posting that great lesson.

You might have read a post of mine, a month ago, re a water leak. We left for a week in the mountains north of Tucson. First night at Lost Dutchman, no leak. Second night we had a leak coming pretty good out of the hull weep holes rear curbside. Due to the location, I figured it was the lines near the water pump but I didn't want to deal with it on the road, so we only turned on the water pump briefly while using water.

Later it leaked right front, and on another day left rear! It depended on the level, so I had no idea where it was coming from.

When back home, I thought why no leak for 24 hours and then leaking for the next 5 days? I thought to mentally retrace my steps during our first overnight. Then I remembered, I had used the outdoor shower to rinse some equipment. I had left the valves on and it was only the handle switch keeping it from pouring out hard.

We all do dumb stuff! 🤣

Love our Truma and glad you got it resolved! We learn from experience that we learn from experience! 👍🏻😊

I'll try to remember that the next time I'm standing in the shower ankle deep in water because I forgot to open the drain valve.🤪

No worries.  We all learn from each other.  Our outside faucet knobs are hard to move also.  Maybe it's designed that way to make sure they don't wiggle open.
