Chosen Solution
I inadvertently placed a jar with paper label into dishwasher. Part of the paper label washed off. Now there is standing water over the screened drain. Will this resolve itself after many washings? I tried pouring white vinegar into the dishwasher to see if this would help dissolve the paper and drain properly.
Stick your hand in the water by the drain and get the label out.
it should, but I would try one of those dishwasher cleaners to speed up the process.
