Make sure the detergent has enzymes in it, they clean much better than
detergents without them.
What brand(s) that you know of have them?


According to Consumer Reports, enzymes were what seperated the great
detergents from the poor ones. Most brands have them in some, but not
all, of their offerings. I use the gel or tablet version of
Electrasol. Read the box, if they have enzymes, it's there in the
fine print.

I'd also check water temp. Mine wasn't washing that great at 120,
which was the min spec. I raised it to 130 and it make a big
difference.

Read the manual and check any filters and all nozzles in arms for
blockage. If that doesn;t do it, then IMO, it;s not worth a service
call. Just wait for a sale and get a new one. There are also some
great deals on Ebay, but the usual cautions apply.
