I have a Bosch SHE4AM12UC dishwasher that hasn't been draining. i have searched other forums and have already done the following:
1. Disassembled the drain line and made sure it was clear from drain pump to garbage disposal.
2. Disassembled drain pump and cleared impeller.
3.Cleared internal screen.
The unit drained for a couple of washes but is back to where it was.
The drain line runs down low through a hole in the side of the cabinet and then rises to the disposer.
I have heard that it should run just below the counter top then drop below the disposal entrance and then up to the disposal. Is this correct?
I also would like to know how to skip to the drain cycle on this model.

Thanks,
