Steven E San Jose , CA July 10, 2015 We used the wrong type of soap for many years and all the spray arms and filters got all clogged up I replaced all the filters and arms. Cleaned out all the built up gunk. Runs like a charm now. There is a tiny bit of residue left and still spraying out, but I think it will clear in a few more cycles.
