I had a problem with my dishwasher in that it wouldn't drain after the wash cycle. I called Roto-Rooter drain service to have them check the drains and remove any clogs. The technician, Robert, trouble shot the drains and it turned out the problem was with my dishwasher. His service was prompt and he helped me to determine what the real problem was. Unfortunately, I have to replace the dishwasher but at least I know I am not taking on a needless expense.
