The drain line has been checked and is open. The strainer in the bottom of the dishwasher is clear. I can hold the open end of the drain hose at my head height, and no water will be pumped out, but when I lower the drain line, water will pump out, but with not much force. I also have experience with a portable dishwasher, and when it drains, the pump forces wht water out with a lot of velocity. That's why I suspect the pump in the Roper under counter dishwasher. What do you think?
Considering the information I gave you, do you think the pumpis the problem, or is there something else that should be investigated?
