Mike L. for Model Number shx45m05uc/50 Dishwasher not consistently draining. Recently replaced fill valve and now it's not always draining. No clogs in hoses, I checked everything. When I had DW slid out, I manually activated the float switch to check the pump impeller. I determined that it does not consistently activate the pump. It always causes the pump to make a humming sound but not always activate the impeller. Thanks
