I took the strainer cover, the one with the sharp pieces pointing dow,n and the strainer underneath that out. I used a wet/dryvac to get the water out because it had not completely drained. 3 - 4 cups of water. I ended up with a small white marble sized ball in the vacuum tank. Could you please tell me where to put this back? Also, how do I get the blade arm off? I had a hard time getting the baskets out without removing it, but I managed. Thanks.
