Truma combi 4-No power

[Pennee]

I’m loosing the will to live with this van but this week I’ve had a new combustion fan fitted. Worked great until this afternoon, came back to site after a walk and no power to the controls and the following error code which we’ve checked and checked again
Lsllslsl
I’ve changed the fuse in the main board (the main board and controls were overhauled two weeks ago by Apuljack Electronics) and no change.
Anyone a master in these codes?
It doesn’t help that access to the boiler in the first place is rubbish so you can hardly see what’s going on.
Thanks in advance

Not much help I am afraid, but the code lsll slsl comes up as fault code No181 on my list = unassigned - action = recheck flash code

And for me that unassigned code comes up.
I’ve even had my 11 year old sit and watch and she gave me the same code twice also. Frustrating!

Are you able to check that the multi lead that connects the combi to its controls is pushed fully in. (it is close to the fault code flashing light)

 

[Pennee]

Interestingly one lead wasn’t in at all. A black one so I’ve pushed that in now and still nothing. Guess I need to get home tomorrow, remove the pipe out the way and then the cover to see if there’s a reset option?

There may be a very small reset button next to the fault code light under the cover (press and hold down a few seconds then release) or the other thing you could try for now is switching the combi off at its controls altogether for 1x min and then trying it again.

I haven’t got a screwdriver short enough to get in the gap so will have to wait until I get home. The controls itself have been off a couple of hours and when I try and put them back on nothing happens. I’ve also switched off the mains trip and nothing changed. Will have a look tomorrow when I have a shorter screwdriver! Thank you

 

[GeoffnDee]

There is a 12v fuse under the cover on the combi that you can also check when you remove it. Hopefully the reset button or fuse will sort it out.

 

[Pennee]

Thank you. I’ll have a look tomorrow and let you know how I get on

 

[Pennee]

Well for the life of me I can’t get this cover off to access the fuses and reset. The dam screw has been rounded off by whoever fiddled with it last. I’m just going to have to wait until the mechanic can get here

Pennee Until you are able to get the cover off the boiler electrics to check things out , it may in the meantime , be worth checking that the control wiring plug in connections on the rear of the Truma Combi setting controls are fitted ok.

Getting the timing right for the reset procedure is difficult unless you follow the led lights under the clip on cover.

 

[Pennee]

So sorted everything cover wise. Changed the fuse. No flashing lights anymore but still no power. I can’t decipher if no flashing lights is good or bad but I’m going to try and book in with Truma in Derby I think because I’m sick of all this back and forth with it. Just want it done and dusted now

I also forgot to add that now the fuse light is flashing in the main control panel for the van which wasn’t before
