Truma Varioheat furnance not working with error code

[Mike and Jill]

We're currently out camping with our 2 month old Legacy II, when our Truma varioheat furnance went out and started putting out codes. When I set a temp calling for the furnance to come on, a small audible click can be heard about 10 seconds after setting the temp and then error code "E 13 H" will show on the cp plus display. I've searched the everywhere I can think of on the internet including the truma site for a explaination for this code, but haven't been to find this particular code listed in any of the troubleshooting guides including the manual for the furnance on Truma's website. Tomorrow (after the new year holiday) I'll give Oliver a call, but today being the holiday everyone is closed.

I have tried to reset the code on the display, however, it keeps returning (the error code) on each new attempt to start the furnance. I also pulled the 10A fuse for the furnance to get it reset as well, but this didnt fix it either. The return for the system is also clear of any obstructions.

It's not the end of the end of the world but its getting down to the 40's tonight so some heat would be nice if anyone has a thoughts or has dealt with this code before

Thanks

Couldn't find that error code either. Did find a couple of British YouTubers showing how to reset the control panel to clear some errors. Not sure if the American version is the same. Here's one:

You didn't mention the conditions under which you are camping. Are you boondocking or in a campground with full hookups?

If you have electricity, I would suggest going out and buying a small electric heater. It will easily heat your trailer to 70 degrees or more. We keep one with us at all times.

If you are boondocking, just put on some extra cover or clothes. You could still buy the electric heater and run it off your generator or for short stints off the batteries. How long you can run the heater is dependent of the type batteries you have.

We even carry a Mr. Heater Portable Buddy gas heater that runs off a small propane bottle or a larger tank with an auxiliary hose. We like to have every eventuality covered. I don't like being inconvenienced by something breaking down on the road.

Could you have accidentally posted the error code incorrectly?

Error Code E513H

 

 

Fault E513H

This is a fault with the Over heat thermostat. It normally occurs when the heater is asked to heat the water on the HOT setting, and may be intermittent, but the system may be fine on the eco water heating setting or if the heater is just being used for space heating.

Thanks ScubaRx and Dud B.

Dud B, I did try the reset in video you replied with and the same condition or code returned.

ScubaRx, thanks for ideas and yes we do need to bring a secondary heat source in the future. Tomorrow we're pulling stakes and heading home from this little shake down run with our Ollie. I did see the 513 code and thought the same as you, but it I tripled checked it and it does say E 13 H. 

Thanks to both of you all. Tomorrow when everything opens back up I'm sure between Oliver and Truma we'll be able to get this figured out.

These are great heaters, but come with many precautions; so anyone using them should be well versed. Proper ventilation is key, but even with that I experienced humidity issues when using; condensation on the interior windows would form and run down the wall onto the bedding. Breathing alone can create this condition, but the Mr. Heater seemed to worsen the problem and thus, no longer carry with. However, Mr. Heater is a great alternative to a gas fire pit!

Yep - water vapor is a by-product of burning propane.  Thus, unless vented, the Mr.Heater will simply add moisture to the interior of the Ollie.  I always have the bath door open with the bath vent open plus have either a window cracked or have the main ceiling vent opened when using my Mr.Heater.  As Ron states -

That's a code for the water heater/combi. I saw the same. I'm not sure if they're the same, on the varioheat furnace. 

Good try, though.

@Mike and Jill, any updates, now that everyone is back to work at Truma?

Yes, I talked with the Truma center in Lakeland Florida yesterday and they stated that code is "fan speed too slow".  In conversation, the tech stated that more than likely I had a mechincal fan failure and the unit would need to be replaced. Being that their repair center is only 2 hours from us, we are scheduled in Feb to have looked at or replaced. So a little bit of a wait but very happy to have Truma actually doing the work.

Mike and Jill - 

Thanks for the update!

Hopefully Truma will take good care of you.

If you have children or curious pets, an oil filled space heater is much safer to wandering hands or tongues.    But they do weigh a bunch more than the typical 2 pound space heaters sole at Walmart.
