I have a Bosch dishwasher SHU43C model. I assume most of them are similar in assembly/disassembly. How do you remove the bottom in order to get to the pump/motor? I have a buzzing sound coming directly from the pump(I can feel it with my hand). I'm thinking something is clogged in there, so I'd like to clean it out. From the looks of it, the pump looks like one solid piece that can't be taken apart. Or can it? I can't figure out how to remove the bottom white plastic base to get better access. I removed the base from the back of the unit, but in the front, there is a pulley and string mechanism that won't let me pull the front of the base away more than an inch or two. Any ideas? Thanks.
