Hi there!
I've found theSpec Sheet for you. This will tell you what your model is and what it does -

I suggest you email their customer service desk for a copy of the guide to be mailed out to you, as I can't locate a PDF version.

In the meantime, You will need dishwasher salt, detergent and rinse aid.
Salt is salt whatever price you pay for it, But dishwasher salt is made into large granules. ( As you're on a yacht it seems ironic you have to buy salt, but there you go)
This will normally be put into a screw cap in the base of the machine inside. You may have to lift out a filter tray to see it.
Fill up with around a kilo. Expect water to come out as you do this. Don't worry - that's normal.
The rinse aid is normally filled on the door panel. Expect a little funnel with numbers near it - just top it right up or to a mark, or an indicator which changes colour. No harm in overfilling - just wasteful.
For your situation, I'd recommend dishwasher tablets that are plastic wrapped - so they dont get damp.
This should go into a drawer or flap on the door, but if not, put it in the utensil rack - it will clean just as well on standard washes, just omit the first rinse if there is one, or load up in stages - rinsing untill you have a full load, then pop a tablet in there before washing.
If this has helped you, Please spare a moment to rate as Fixya! Thank you.
