LDC, I have a Beko slimline too, I raised the top basket to the highest position and it fits my dinner plates in. In the lower position the plates were too big.
I use half a tablet (any that are on offer) and find the dishes come out just as clean as when using a full tablet.
I usually use the half hour quick wash, but occasionally use a long wash and stop the program before the drying cycle begins, open the door and let the dishes drip dry to save on electric costs.
I love my dishwasher and would hate to be without it.
