I have a two year old Kitchenaid dishwasher that during the final rinse, I found suds in the bottom of the appliance this has been happening for several days. The suds are not coming from the detergent as I have checked several times during the wash cycle and there are no suds during the wash. I can't seem to get rid of them. I've used a sprinkling of salt but this just makes the inside gritty. I recently topped up the Jet Dry. Could the suds be a result of too much rinse agent? The dishes are clean and spotless. What can I do to get rid of all these suds?
