Question Thule C3402/ 6002 Boiler Help Needed Please! Pint to be won!

Hi Everyone,

This is very new for me - Never posted online in my life So good eve all! and hope your well!

Bought my first MH at 17 Years old - A Mitsubishi L300, she'd be a 40 year old machine these days - but quite the dancer!


Recently bought a Hymer B544 1998 (My Dream Machine) and quickly found the salesman had lied on many points, Found the dash had rotted, roof was leaking, water pipes were leaking - most things were shot really - I understand second had motorhomes have a few things wrong, but this took the cherry on the cake.

Jumped in and started reno's, as been the MH i always wanted - decided just to make the best of it and also allowed me to put a stamp on it, so:

-Made a new Dash
- New Sound proofing
-Cut new carpets
-Replaced skylights
- Sealing all external joints
- Began spray painting all plastics, walls
- Rebuilt the cupboard, passenger side
- Fixed External door locks

The list goes on,

Then..............

The boiler failed

I'd saved up such a long time and reno's have cost so much despite doing the work myself, this really was the cherry on the cake! Now the colds coming in, i can't continue to work and my holiday is just about done


If anyone can help with this i would be very grateful!

So the problem:
  • Boiler was working fine on both Blown Air heating and Water.
  • Gas: Propane
  • Regulator fitted: 30Mbar
  • Boiler: C3402/6002
  • Boiler: Gas only
  • Gas at the cooking hobs - No loss in pressure when i turn the boiler on
  • Boiler exhaust fan blowing: Checked the outlet for pressure
  • Igniters sound to be clicking: Unsure about spark
  • Gas valve 'sounds to be opening'
  • Fuses on PCB are all checked and fine

If anyone has ANY thoughts at all i would greatly appreciate it - Maybe you know the startup sequence sounds, or know its jippy if its cold outside etc everything helpful.

If you can find the solution, when we meet somewhere in MH land, i'll by you a pint or two!


Best Regards

Mark

I had similar problem and I thought the gas had run out, but like you the cooker was still working.
Anyway I decide to change the gas bottle and all worked ok.
It turned out that there was very little gas left in the bottle so not enough pressure to run the boiler.

Many thanks for the reply Peter,

I did change the gas bottle with a new one, but that has made me think - maybe the regulator isn't giving enough pressure? 👍. I'll try and find a new one tomorrow and swap out.

I'll let you know the results.

I seem to remember somebody on another forum having a problem with their boiler and they put electric feed straight from battery and that helped. Maybe worth a try as a temporary check.
