One of the most common reasons your dishwasher won’t drain well is due to a clog in the drain tube. This drain line, or drain hose, sends water out of the dishwasher tub at the end of a cycle. If the drain line is clogged, water isn’t able to flow out of the tub. Contact the Parker Pearce Service Experts pros at 301-476-4577 for plumbing services in Gaithersburg.
