Truma combi 6E Warwick Duo 2016

topic probably been covered before, however I'm unable to get the water to heat up on either E1 or E2, followed the instructions to a letter , read the manual online, still no joy.
I did notice I'm not getting the wee electric plug symbol on the Truma panel.
I have removed the metal cover from the top of the unit to reveal the boiler, taken the side plastic panel of, the 12 volt fuse looks fine? ,couldn't decide if the mechanical overheating switch was in or out,how obvious is it ?  
How the hell do you find the 230volt ,10amp fuse without dismantling half the boiler ,works fine on gas, heats up well on electric heating.
Otherwise loving the van.

Check the 230v distribution board to make sure the breaker is set to on. On our Warwick there is a fused connection unit attached inside the cabinet housing the Truma. It has a switch and a fuse, check both. 
I think is is an overheat trip inside the boiler too.

Will assume it’s the same as ours being a 2016, and you have checked the Water Heater Switch behind the drop down flap revealing the electrics which should be lit.  I found the eco setting is as much use maps a chocolate fireguard if it’s set on eco

Hi Roger
Water heater switch is on and lit up, tried all three on electric settings, still no joy.

I've pressed the overheat trip button, at least I think I have,nothing moved, I've checked all the obvious fuses , not the mains T10 amp one inside the unit, carnt find how to get to it.

If it works on gas it is not the overheat trip.
If it blows hot air on electricity it is not the 240V fuse on the boiler.
If it does not work on electricity it is worth checking the fuse on the boiler.
To get at the mains fuse on the boiler:
(1) isolate the van from mains
(2) Pull up the cover for the 12V control panel and remove.  (I think that you have done this)  Be careful of the several plugs plugged into this board.  You should not need to move them and they must be just right,
(3) There are two TORQ screws that you been to unscrew to remove the cover to the mains panel.  remove these being careful not to drop them.
(4)  This panel should now henge out and away from the boiler
(5) The fuse is on the PCB now exposed. If you are looking from above it is hidden by a terminal block.  

BUT do not go there if electrical heating can be obtained at all - it will not be the fuse.

Thanks for the easy to follow check list, I'm getting heating on gas and electric , hot water on gas, but still,no hot water on electric..
Thanks for your help Safariboy .

There are two 900 watt elements, maybe one is naff, heating on only one element would be slow.
But then your heating would also be poor so that's probably wrong.

For what it’s worth, we have always found Truma ( Dove Valley estate, near Derby) to be very helpful and easy to deal with. It might be worth ringing them and explaining your problem.

When last we visited they said they were trying to attract people there to have their heaters serviced or repaired and, to that end, have excellent facilities for doing the job. Even includes a vast full English breakfast, free!

Could be worth a trip down there Quilter, I'd travel to the end of the earth for a FEB  prefer a full Scottish with black pudding, square sausage and tattie scones.
Seriously , worth a phone call to point me in the right direction, thank you.

I expect that the water gets hot when air is being heated.  If so your symptoms point to either a faulty thermistor in the water tank or a pc fault.  In either event you need a Truma engineer.

Thanks Paul, the wee electric plug symbol isn't showing on the Truma CP when hot water is selected.   
Have sent Truma an inquiry regarding the subject, so should get a reply next week., not having hot water on tap (on electric) isn't going to spoil our trips .
Nice and sunny at dawn,should hear the dawn chorus ,wow

Ah, the advancement of technology! I don't have a Truma CP with symbols only two turn dials with symbols. I read posts of fault codes on the panels, none of that with mine, it either works or it doesn't, and so far, touch wood, it always works.

The fault codes are shown by the yellow light flashing.
For example 2 flashes followed by a gap is no 240V to elements. Etc.

I was referring to these codes...

To be honest Paul, I preferred to old soldier proof units ,didn't seem to have any hassle with them, only broken catches, burst pipes etc.
We can manage with the Combi 6e until June, it's needing a service ,so will properly head for Derby then.

Don't eat to many Easter eggs.

Just seen this on FB. Don't know if it's relevant....





A flashing Code E-514-H displayed in the Truma control panel is due to an incorrect shut down of the electrical system.
The heating system now requires turning off at Truma control before powering down the van or turning the main 12v master switch off.
In the event of a system code E-514-H displaying in the Truma control panel, keep the power on AND leave the control panel alone until this code stops flashing, this will take approximately 15 minutes. Once the code is ready press the Truma control panel button (large round button centred in the bottom section of the panel) twice to continue as normal.


Hope this helps

Hi Paul
Hubert put me right ,I had to press in the space heater button as well as the water heater button, the wee electric plug symbol now shows on the Truma panel and shows the wee electric symbol on the control panel above the door.
However ......... The Truma unit gets very hot when on electric 1 or 2 , to hot to touch in fact ??, anyway just going to use the gas to heat water and warm up on electric.
I feel such a dummy, didn't know I have to select the space heater/water buttons to heat the water , should read the instructions more than ten times .
Boaby

BB, whilst you can obviously use different fuels for hot water and space heating when done seperately, you cant select different 'fuels' for hot water and heating... at the same time. 
whatever you select is what it uses...for both, if on.

there are some quirks of the power supply system that aren't always obvious, but are mentioned in the manual..

eg...when selecting mixed mode(gas and electric) and hot water only is selected, the unit only uses electric to heat it whereas it uses both fuels if space heating is selected.

similarly, if gas only is chosen for space heating it will use upto 6kw (outputs of 2/4/6 may be used) depending on the difference between the thermostat setting and the ambient room temperature ie how quickly heat is required.
..whereas, when using gas only for hot water only, the burner will only use the 2kw gas level. which is good enough for a hot twnk in 20 mins or so.

Hi Chris
Thanks for walking me through the manual and explaining it in more detail .
I've only been getting to grips with the Truma combi 6 system since the threat of morning frosts have gone .
I'm fine with the gas side now, not used the mixed settings yet, heats the water up well.
The Electric on E1/E2 working well and brings the heat up nicely. Tried it this morning.
When I select E1/E2 to heat the water, the unit gets very HOT and has a strong electrical smell coming from it, I have to turn it off.
Anyway Chris ,it's due a service I think,so will book it in for one in Derby in June.
Thanks

Just read your link Paul, after getting the water heater on now, that's the symptom I'm getting went on electric for hot water.
Worth a visit to Derby I think.     Fancy a free breakfast .

We can always smell our water heating up on electric and were told it’s normal and the smell comes from the insulation. 

Whatever, it’s been happening for 18 months from new and, once up to temp, the smell disappears. It’s not a concern to me.

Hi TW
It gets really HOT,to hot to touch, I've had vans for over 40 years and had nothing heat up and smell like this.   
Thanks for your help
