Truma Combi4 problems (1 Viewer)

[neesyanne 3]

Hi all, Am currently on hook up and the Truma Combi4 has gone into fault.It works on gas only but wont work on either gas/ elec or elec only. The red light just flashes. Have gone through the Truma book but to no avail.Have checked the safety cut out button on the boiler and under the floor in the locker, the lid of which buried itself in the top of my head so I now have another headache.The lights on the boiler are working so the fuse must be OK. I can take aspirin for one headache but need your expert opinion on the other one.

On the actual panel on the boiler (not the wall mounted controller), if you remove the lid you will see another flashing light - it changes the frequency of flashes depending on the fault. The Truma book had details of the flashing sequences to determine the fault (there sare lots of different ones...).

I had a problem with mine and found a second time delay fuse had blown... it was a bugger to get at as it is at the bottom of the boiler panel and was under the bed.

I hope it works because my motorhome Truma combo has the same fault. Please let us know the outcome.

@jdk62 Is the fuse behind the plastic cover and if so how did youmanage to get it off?

 

[jdk62]

The plastic cover on the actual boiler has a little catch at the top - I used a screwdriver to encourage it apart. The red light is at the top, along with a fuse. The second fuse is at the bottom.

Thanks the boiler is under the Lshape seat and is a pig to get to and my old fingers and Knuckles wont twist like they used to so its probably a Truma centre job.

Yup 10Amp fuse blown. Dealer said common fault as 10 amp for europe not for uk power system.

My Truma fault was also the 10amp fuse being blown. I had about 8 hours work to replace the 31p fuse.

I have had this fuse blow twice and also helped an onsite neighbour change his. Very awkward to get to because I can only squeeze my hand in flat. I found that by dangling the fuse on a half knotted loop of cotton thread I could then position it over the fuse holder and then only had to push it into place with my flat hand. Easy enough to pull the thread out after this by letting go of one end. Packet of slow acting 10 amp fuses bought from Maplin.

In our experience for Truma read Trauma. Had loads of problems over the years which have cost loadsa heads and spadukas.

That should be Headaches not just heads. Oops.

Could really help if an exterior access panel was available to work from the outside. Ruddy terrible place to put the control panel fuses.
