Chuck T Marietta , GA September 26, 2020 Appliance: Whirlpool Undercounter Dishwasher WDT710PAYM4 Whirlpool Dishwasher Wdt710paym4: Spray arms (recirculating pump) stopped working. How to replace Dishwasher Hose Clamp. Ordered the pump (and easy to install clamp) and received it two - three days later. Hardest part was unhooking all the drain and water supply hoses. Old pump came right off and new one went right on (after swapping outlet grommet). I’m 70 years old with just moderate DIY skills and the job was a piece of cake. Start to finish only took a couple of hours. All the videos I watched (3) helped greatly. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
