I’ve noticed ants coming in and out of a hole near where the water tray sits. I’ve been trying to get the bottom off the machine by removing every screw in sight, but the locking/unlocking wheel is the only thing stopping it from coming up. I can’t seem to take the wheel off, or loosen it up. any help appreciated. thanks!

Hi, Don’t know the answer but here’s a link to the parts for a BES900 that has two .pdf diagrams showing all the parts so perhaps they may give a clue as to how to remove the drip tray. Hopefully this is of some help until a more definitive answer comes along.

Plug on the top surface of the knob(the one that lifts the roller up). It has a screw under it.
