Truma Combi error (1 Viewer)

[Dazzler1969]

hi all,
Just getting sorted for a week away and filled the system with water after draining down for winter. Closed off frost protection unit, opened taps and switched pump on! Water running perfect through taps, turned taps off and pump stopped. Go to test heating and fire it up, unit comes on with E 117H which according to Truma manual is something to do with summer setting?
Drained down again and started again with still the same error, I can see no reference to summer mode in any booklets I have, and nothing of any help on internet!
Any thoughts or anybody experienced this previously?
Vehicle is Pilote with Truma 6 Combi heater.
Many thanks
Darren

Did you draw the water through the hot taps in order to fill boiler? I think summer mode is just water heating and therefore needs water in the boiler. Winter you can heat van with hot air and doesn’t require water in boiler.

 

[Dazzler1969]

Yeah, done that 3 times and still nothing! Call to Truma tomorrow I think.
Thank you
Darren

I assume it was it working 100% prior to winter drain down? , if so have you also made sure that the gas is getting to it.

I think summer mode refers to switch setting from what I remember the summer setting is without heating on the dial type switches.

Can’t find e117h but there is : #17 in list saying : Summer boiler mode empty water container.
Remedy : switch heater off allow to cool. Fill boiler with water.
Has the boiler perhaps got an airlock has the boiler perhaps got an air lock and not filling fully?

sticking non return valve?

 

[Dazzler1969]

@Speve yeah I think that might be the case although I can hear it filling, just wondering if there is an air valve near the heater as opposed to the frost valve which is on the opposite side of the van.
@Bart it was all working a couple of months ago, not sure how to check at heater side if gas is getting through but I can hear a couple of clicks when the control panel is switched on.

Sorry can’t help much there but there may be a valve on the top of the boiler?worth a look.

 

[Speve]

This might help but can’t find a bleed valve but does show inlets and outlets etc.

Is the gas running OK to the other appliances, fridge / hob?

 

[Dazzler1969]

Hi,
Gas running perfect to everything, it goes in on tues for a couple of warranty bits! Reading about pressure needing to be higher than to the fridge / cooker etc so a possibility of a regulator fault, it is a possibility as I struggled with it slightly last time it was used but thought it was me being an idiot.
Will post when I know more.
Thanks for your input, helpful as ever.
Cheers
Darren

Just thought I’d give you an update, this might help somebody along the way........
Apparently Truma have changed their software from 2018 onwards in that it checks gas pressure first and if there’s an issue you get the error code straight away, in the Pilote you have their new “experience” tablet alongside the Truma panel and if they don’t go on in sequence you get errors.
1st gas on, 2nd Truma panel then experience tablet. Hopefully that will cure my problem......famous last words.
Thanks again for your comments.
