Things are looking a bit grim for my Wallas 1600. I'm living aboard part time at the moment and the temperature outside is getting a bit beyond a joke!

It stopped heating up and I had a go at cleaning the fuel filter. Got one evening's heat out of it and then the usual 'click' which I take to be from the fuel pump stopped happening- and once again, no more heat. I'm assuming that having worked too hard against a clogged filter, the pump has had enough.

According to the manual, the pump is a Wallas-designed electromagnetic device which provides a metered quantity of fuel. Sounds a bit complicated.

Kuranda and David (East Coast Marine) of this forum have suggested that it may be time for a new heater :(

Just wondering if anybody has any advice before I take the plunge. Perhaps there's a way to recondition/rebuild the pump. Or replace it with something that would do the same job. Maybe I could arrange a gravity feed, for example?
 
Kuranda hve been good at fixing my parents Wallas and more recently mine, mine was under warranty.

I packed it up and sent it back, turn round was only a couple of weeks IIRC.

Have you tried ringing them to see how much a repair will be?

Is this the bulkhead mounted jobbie
if so i had one from new, Simpson-Lawrence, the importers had mine longer than me due to repairs. The PCB always had one or other component burning out. It was very good when it worked
 
If it needs a new pump and none are available then short of the unlikely possibility of finding a used pump then the only solution is replacement. However it may be worth the small investment to remove it and ship it for proper bench diagnosis, at least then you can be sure.

That's the heater off the bulkhead and taken apart so that I can get to the pump. It's not the sort of thing that inspires me to do any further dismantling.

Here's a crazy idea. If I knew what sort of flow rate the burner needs, could I not set up a gravity feed system? There is a fuel return line which presumably could deal with a certain amount of excess, flowing to a collecting tank. Swap the tanks round when necessary. Not elegant but, like I said, getting desperate here...
 
Update...
the pump itself seems to have some life in it. Applying 12v to its terminals momentarily gives a nice click. I'm going to look elsewhere for the problem- e.g. perhaps the temperature sensor is duff? Or something else up on the electronic side of things which is stopping the pump being told to do its job.

If I haven't managed to sort it this weekend, I'll contact Kuranda on Monday to see if it's worth sending it to them.
