My dishwasher wasn't draining, so I took apart and cleared out the sump and micro-filter drain per instructions on this post
Unfortunately, it didn't work, so I pulled the dishwasher out and checked the drain hose and red one way valve. Still not draining.
The last bit of info is that during what I think is the drain cycle, there's a hum/buzz sound coming from what I suspect is the pump.
Are there any other troubleshooting steps? or am I stuck ordering something like this
, for $175? Is there a cheaper part that might be available?
