I have an earlier version of the Truma Combi than yours (our fault codes are transmitted as a 'morse code' series of flashes) but a quick look online shows:

W = Warning
H = Furnace (presumably meaning boiler)
The number in the middle is the 'error code' and 18 refers to either:

a) Warm air outlet blocked - check the individual outlet openings.
b) Circulated air intake blocked - remove blockage from circulated air intake.

HTH

warm air outlets blocked. Check all warm outlets are open and check circulated air intake for blockage.

I had the same warning on my Truma Combi 6 last trip out, the wife had put something in front of the air intake vents for the combi boiler which in our van are under in a space between two seats she thought it would be a good storage area for some boxes,removed the boxes turned the power on and off to reset the control and problem solved.

In my previous MH there was one outlet which. could not be closed. It was in the shower. I was surprised to find all the outlets on my present rapido can be closed, which seems dangerous so I have wedged one permanently open.
