Whirlpool WPW10077859 Water Supply Tube OEM Part

Found a torn valve in the feed tube assembly and replaced the entire feed tube unit.

Ordered a new tube so the flapper valves would be clean and close properly. The old flapper valves had buildup on them and would not divert the water to the upper spinner. The cups would get a soap/food scrap residue that hadn't been cleaned off. Wish I didn't have to buy the entire tube and could just get the flapper valves/assembly separately as the tube was fine, just needed the diverter/flapper valves, but price was pretty good and it arrived in a moderately decent time. Snapped right in, and we're in business.

I replaced the chopper with new unit and also replaced the water tube to the overhead spray bar due to a failed check valve. The parts were a direct replacement and the repair took 30 minutes. The dish washer works like new!

Water ports on feed tube wore out so water was not reaching top sprayer. Replaced feed tube in just minutes and problem is solved

Restored pressure to the top rack spray arm by replacing the water supply tube. The tube in my model has two valves, one of them is supposed to be closed while the other is open and supplying water to the top rack spray arm. This fixed my washer and now it's working fine.
