How to replace Drain Valve (Water Drain). Removed the machine from under the counter. Replaced each of the parts starting with the circulation pump. The circulation pump mounting plate should also be replaced because this part is very flimsy and the mounting screw holes are easily stripped during the process. You will need a torx bit set. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
