Mitch W Greenwood , IN June 21, 2019 Appliance: Whirlpool Washer WFW94HEAW0 Whirlpool Washer Wfw94heaw0 / : Error code E1 F9. How to replace Washer Drain Pump Assembly. Water leaking out of body of motor. Had to replace entire pump assembly. Washing machine model did not have easy access from front. Have to remove top cover to access screws to remove from cover. Because dryer was stacked on top and very limited space around the appliance; repair was performed from the back. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
