GE Profile not draining

My dishwasher wasn’t draining, so I took apart and cleared out the sump and micro-filter drain per instructions [like this](http://forum.appliancepartspros.com/dishwasher-repair/16487-ge-profile-dishwasher-wont-drain-completely.html"]on this post[/URL].

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 [URL="http://www.appliancepartspros.com/ge-mechanism-asm-wd26x10045-ap4508069.html#qa1), for $175? Is there a cheaper part that might be available?

Thanks!
Mark
