I found a couple of threads here debating the relative merits of the Dickinson diesel
stoves for heat and was hoping to tap the brains of fellow owners with an annoying problem I've been having with my Lofoten.
The stove has worked wonderfully for the past couple of years, and presumably before that for the previous owner of the boat. Recently, after a period of infrequent use, it has started going out on us randomly. Checking the stove, it appears when this happens that the fuel
flow has simply stopped. There is fuel
in the tank (gravity fed, installed to spec as far as I can see) and the valve can be set to any open number (1-5) but regardless of setting, no fuel comes out of the feed hole.
We have been tearing apart the valve assembly to see what is wrong each time, and there never appears to be a problem. However, after assembling it again, the stove works: fuel flows, it lights and burns normally for some random period of time.
I thought at first it was bad fuel; a bit of water
or crud choking it or blowing it out. But that doesn't explain why no new fuel feeds after it goes out. There has been more fuel than usual in the overflow line so I thought perhaps it was feeding into the assembly too fast and raising the float which (I think) cuts the flow off if it overflows. But it happens even if the valve is at the lowest setting, and I have constricted the flow with a smaller filter screen
with no effect. Also, it doesn't seem that the fuel in the assembly is always excessive when we tear it down, only sometimes.
The last time it did it, I just unscrewed the top plate of the valve assembly and lifted it up slightly, then replaced it, and it started working again! No idea at all why.
If anyone has any thoughts, I would love to hear them! If I don't reply, it's not because I'm ignoring anything, I'm just out cruising with only intermittent network access right now. Thanks!
