I just picked up a dishwasher with a draining problem. The drain pump motor seems fine (I replaced it) but water doesn’t seem to come out when it runs. I have even connected it directly to 110 AC and the motor spins, but nothing comes out. I’ve tried flushing the drain line and water goes out but none will come in the reverse direction even if I bypass the check valve in the sump. Any thoughts?
Thanks,
Graham
