Hi Jacob,
Congratulations on the dishwasher!
You are looking at around 99/2000 if it has the Universal 65 cycle. The later versions from around 2001 had the Intensive 75 cycle rather than Universal 65, and were sold up until 2005.
The dishwasher is very smart, and perform beautifully. I had one for a while a couple of years ago and most things will come clean on the normal 50° cycle which only takes about an hour. Universal plus catered for anything that was baked on - never needed to use Intensive.
