Bosch Circulating Pump

I have a new circulating pump for my DW and need help removing the old one and installing the new one. Any help would be great.

See this thread, it has a pretty good explanation. I am currently in the middle of this job. I think I will replace the whole pump, this is a big job and I don’t want to do it twice.

One lesson I learned, take the dishwasher out to the garage before disassembling it. You’re basically taking the whole unit apart, too much work to do in the kitchen. Also there is a service manual floating around, you will need this although there is a step missing for taking the tub off the base.
