hi, did anybody ran through that ‘dirty flame sensor’ problem, yet?
It ignites the flame but after a few seconds the gas valve shuts. I can feel the flames heat at the exhaust.. Gas pressure and voltage are ok.
Has anybody had it open and cleaned the sensors, yet? Easy to open?

Tackle it from outside your van, remove plastic cover and frame , blast it with air from any means you have.
I have used servo air hose, leaf blower successfully. Dust is the enemy

thanks a lot, that sucks. What do we do if Mrs wants hot water all day, so cover has to be off... on a windy day at
the beach or out bush...?

Can you devise a metal cover that would allow sufficient exhaust but limit the ingress of blowing dust, rail etc?

Pedro is advising to CLEAN the offending area with a jet of air to remove dust, after which the heater should work normally it that was the problem. He isn't suggesting having covers, etc, off permanently to achieve hot water production. Are you thinking otherwise? it seems as though you are. Frank's suggestion of a shield of some nature may minimize the return of the problem and hopefully eliminate it altogether. Maybe a travel cover over the heater vents ONLY while you travel will assist. You don't need hot water while driving along.

.
It could be dangerous to meddle with the manufactured ventilation arrangement, but a cowl-cover is provided for the Truma and is recommended to be fitted for travel. Are you using this?

I had the same idea, to use an exhaustion fans air filter material to keep dust out. I am afraid that dust with air humidity or condensation over those wet days hardens the dust and makes it impossible to blow off.

If you look at any Australian Off Road vans (AOR) you will see they have manufactured a drop down metal lid which encloses the plastic lid when travelling . Keeps out dust and water. Maybe you can make a similar cover
