Step seven: slide out the black box and move it aside.
There is no need to detach those three connectors.
See indicated tab below.

This is where you are at now...
.
Now you can access the microfilter cover and remove the filter.... it's a pale green, and has a large black knob at the top and a t20 at the bottom, loosen the t20 (it won't come completely out or fall out) turn the knob and remove the cover.
.
now just pull your filter out,(it's tight but it does clear) clean inside there with a vacuum, your hand and a cloth, both, what ever works best for you. Insert the new filter, and reverse the disassembly process.
