Just put some hot soapy water down the drain hose to prime the pump, set the timer to spin, open the lid, and let it idle. If everything sounds good from there, press the lid switch and see how it spins. Then I'd water test it.
Well I'd say the BD's get points for popularity, longevity, and reliability, but IMO they are dreadful washers. Neutral drain coupled with a pathetic spin are my biggest beefs.
