Do-It-Yourself Story

Drained dishwasher. Unplugged it, disconnected water supply. After laying it on its side checked pump. It seemed to work as impeller was spinning after I took it apart and reconnected it to power. Decided to replace sump as it was deteriorated as well as flapper valve and check valve and hose assembly. Ordered all as well as drain pump. People at Appliance Parts Pro’s were very helpful. Replaced the first three. Still wouldn’t drain. Checked outlet hose. Clear. Replaced drain pump. Still wouldn’t drain. Saw a brass fitting near sink drain at end of drain hose. Disconnected it and lo and behold it had a flapper (check) valve in it that was stuck. Replaced. All is well. Had no idea someone had installed extra valve. Apparently it is fairly standard, but I’m just a DIYer. Wasted a lot of time but did make some necessary part replacements. I am stuck with the pump though as it is not returnable after being installed. It comes with a flapper valve already so have an extra one. May try to send the flapper valve back.
