There is a tiny fuel filter on the inlet to the fuel pump. You have to undo the union nut the filter lives in there. Its a known issue as it is really small and gets shitted up easily. It sits inside the pipe so if you take off the nut connecting fuel inlet to the ticker pump you should find it. Tiny thing. OK I'll have another look tomorrow Thanks If the water pump and air pump aren’t trying to run, it won’t be a fuel filter issue. The sequence of events is water pump on, glow plug on, air pump on after a few seconds and then fuel pump starts ticking, after a few seconds the heater should light off. I recommend Ed Shiers at 4 counties marine. Top bloke. fourcountiesmarineservices.com/mikuni-eberspacher-webasto/

The control box has a fault indicator of flashing lights. If there are no flashes, then there probably is no electric.

The diagnostics diagram pointed to that being the problem so I managed to pick up a 2nd hand one. Same problem As I said I have checked and replaced all three fuses and the switch so not sure what else I can do

If I remember right the indicator light is behind the set of holes shown bottom centre in this image. It does not appear to be a light when you look at it but there is a LED in there I think its a green one. Of course if you have replaced the control unit maybe its a different one which does not have the light.

Its definitely a good arrangement. Assuming you have a solid fuel appliance and are not iced in in the middle of nowhere. I don't think they do ice these days so its probably OK. Seems odd in a way for prop to be more important than heating but if sharing the tank I would always do it like that. Prop is definitely more important or how would you drive your boat to get fuel if the heater used up all the diesel? That would be annoying.

I have disconnected the complete fuel line and cannot find a filter anywhere. I disconnected the fuel pump and then connected it directly to the battery. It 'clicked' and a few spurts of fuel came out but it did not stay on continuously say like a shower pump. Now need to find a gasket for the glow plug boss.....

The fuel pump is supposed to tick its a metering pump not a constant supply type.

Started up a couple of times just to warm the boat in these colder mornings. Then got an unusual whining noise but worked, next day dead. If it doesn't do anything at all then there is little point checking the fuel or ignition systems. It depends what you mean by "dead". You need to establish whether it is initiating the start up procedure. When you switch it on with the remote switch is there a click from the control box ie a relay energising? If so then that would indicate that the switch works and it is attempting to start but failing for some reason.

I gather the usual response from a service technician is to remove the complete unit and take it to a workshop where he has a dedicated test bench. He would obviously check the fuel and power first.

I've heard another approach is to remove the unit to an external deck area, reprogram the user interface with a 4lb hammer and manually propel it in an upward and outward direction across an open body of water such as a canal.

Then replace it with a Chinese one from ebay which cost about the same as a glow plug and a gasket set.

OK I am going to open a can of worms but, IF, I were to change from the Mikuni, and given the present debate about red diesel, what is a better system to replace it with at minimal cost?

If you don't already have a multifuel stove then you need one.
These forced combustion diesel heaters are a nice luxury but not really the thing for full time heating on boats.
If you don't want a multifuel then worth looking at a gravity fed diesel stove like a Refleks. The smaller versions (66) use 70mm flues. Most multifuel stoves use 100mm flues and yes its quite complicated to install and takes up space in the cabin.
But it will stop you getting cold...
