keninpalamos Posted February 10, 2016 Share Posted February 10, 2016 How many have had problems with the early Trumatic C 6000 & 6002 combi heater. It seems the hot water outlet vent has been a problem. A small 8mm clear plastic pipe is connected to the hot water outlet and if the valve sticks or fails water goes down the pipe through the floor onto the road. Truma in their wisdom think if you own a c3400 or 6000 and this 5p plastic valve fails you should buy a brand new boiler at, who knows, the sky's the limit as far as pricing goes. Probably £1200.

Derek Uzzell Posted February 10, 2016 Share Posted February 10, 2016 Trumatic C-3400 and C-6000 appliances were manufactured by Truma from 06/1994 until 06/1997. The design/construction of these heaters differs significantly from the follow-on C-3402 and C-6002 appliances and, for a good many years, if a major fault occurs with a C-3400 or C-6002 (eg. failure of the water-vessel) Truma has said that repairs will not be practicable. Looking at Truma’s on-line documentaion relating to C-3400/C-6000 heaters, it APPEARS that the design of the ‘breather valve’ for those heaters is not the same as the valve fitted to C-3402/C6002 heaters (and to other Trumatic C appliances). What you seem to be demanding is that Truma should be keeping every little spare part for heaters that have not been made for over 18 years. Frankly, that’s unrealistic. If the later breather-valve won’t directly fit on to a C-3400 or C-6000 heater, you’ll need to use your initiative. I‘m sure it would be possible to DIY an adapter that would permit the breather-valve from a C-3402/C-6002 to be grafted on to a C-3400/C-6000.

Derek Uzzell Posted February 11, 2016 Share Posted February 11, 2016 These forum discussions may be of interest http://forums.motorhomefacts.com/60-hymer-motorhomes/97785-anyone-got-parts-truma-c3400-c6000-heater-boiler.html http://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/trumatic-C3400/26337/ (NB. Links in the Out&AboutLive thread may be invalid now.) If none of the ‘elbow-valve’ fittings (example here) http://www.ebay.co.uk/itm/truma-combi-ultrastore-waterheater-elbow-valve-/290658711702 that are available for Truma ‘combi’ heaters and Ultrastore boilers will fit on a Trumatic C-3400/C-6000 appliance (or can adapted to fit), there seem to be a couple of other options. 1: If the C/3400/C-6000 fitting is badly damaged (eg. it has spilit) it might be possible to locate a scrapped heater and remove a working elbow-valve from that (as was suggested on the MHFacts forum). 2: The fitting includes a one-way breather-valve that lets air enter the heater’s water vessel when an automatic safety-drain valve opens. But the fitting’s primary purpose is to act as the heater’s hot-water outlet. The most common problem with the fitting seems to involve failure of the breather-valve allowing water to flow through the breather and preventing the heater being filled with water. The breather-valve is not essential to the heater’s operation and, when an automatic safety-drain valve is not fitted or the safety-drain valve is deliberately jammed closed (a common ploy) the breather-valve becomes redundant. As long as the rest of the fitting is in good condition, it should be possible to blank off the breather-valve part of the fitting, essentially converting it to a simple hot-water outlet. Without seeing a C-3400/C-6000 fitting it’s difficult to suggest how best to do this, but I’d be considering filling the inside of the fitting with Araldite and then drilling out a ‘waterway’ to permit water to exit only from the fitting’s main outlet.

andytw Posted February 11, 2016 Share Posted February 11, 2016 I had a C3400 and made an adapter. The plastic outlet did come off the 10mm pipe once so I had to contrive a method to keep it on. Was fine after that. https://www.dropbox.com/s/qlido9r62u0yvxz/20140108_145003.jpg?dl=0 and some more discussion here... http://www.motorhomevagabond.com/fulltiming/truma-water-heater-problems/ Link to comment Share on other sites More sharing options...
keninpalamos Posted February 11, 2016 Author Share Posted February 11, 2016 Thanks for your reply Derek & Andy. It is unrealistic Derek but fustraiting none the less. The vent is made up of a combination of the original C6000 and the later 6002 which I made some 5-6 Years ago. But things are going from bad to worse and the warm air blower motor sounds as if the bearings are not in the best of health and the space temperature sensor didn't seem to be working now no matter where you set the temp. it just blasts away until it gets so hot you have to turn it off. So I thing it is time for a new C6000 replacement be it the 6002 or an up dated version of that. Price .... EEEK!! Link to comment Share on other sites More sharing options...
Derek Uzzell Posted February 11, 2016 Share Posted February 11, 2016 Not sure it’s possible to buy new Trumatic C-Series heaters nowadays as these were superseded by the “Combi” range in 2007. And, although it should normally be practicable for one C-Series model to fit in the same space as any other C-Series model, there’s no guarantee that a “Combi” will directly replace a C-Series in terms of space requirements.
