Hi I've have a 2019 swift sienia 4sb with the truma air blown heating system and this week is having a hissy fit and keeps coming up with fault code W18H,  I've checked all air inlet and outlet pipes for connection and to see if blocked or restrictive air flow and all is fine.  I've carried out a full caravan shut down for 6hrs while me and wife went out .I disconnected the12v and 240v mains,  next day W18H came back on is the anything I can do while on holiday or do I need to take to dealership when I get home .. cheers mark.

    Hi Mark.  Sorry I can't help, but I've changed to title of the thread with the hope of attracting some help.  Hope this is OK.

    Hi again Mark.  Oddly enough, someone on Facebook has just posted a similar question.... except they called it code E118H?  Could this be the same?  This is the FB reply:

    "Following my error code of E118H that came up a couple of times at the weekend on our caravan I decided to ask Truma what the error code meant as couldn't find it anywhere. They have replied to me today and said the following......

    'Fault code 118 is indicating an issue with the Combi combustion air motor. I would advise contacting your supplying dealer who will need to check the 12v supply to the boiler and check/replace the faulty motor.' "

    Don't know if this helps??

    It looks like we have another thread dealing with the same problem, which has also attracted a few replies, so I will close this thread now.
