Just recently the dishwasher has decided it doesnt require much powder. After full cycle on normal the powder bin is half full and the dishes are still dirty. I have a feeling that the pump pressure is insufficient to clean the dishes or remove the powder from the bin. The water is hot and the filters are clear. Any ideas appreciated

Thanks very much , had a good poke around the arms . They were clean as a whistle. Removed pumps and checked they were clear, and they still had vanes. I have given up the task and taken it to the serviceman.
thanks again
