If a K601 or K701 ever is in my hands again, I fully intend to make a video showing how to disassemble them, but since I first said that I haven't had any come to me for servicing yet.

Turns out that it’s not a broken internal wire. The cable is defective. If I wiggle the attachment end of it, the channel clicks in and out. I can hold it in place and both channels are clear. I suspect this set is a number of years old, since the serial number in the low 4 digits and I’ve seen 5-digit #s for the K601. It’s just a wear and tear problem. I had the exact same problem with a pair of K240DFs I used to own.
Opening the grill piece #24 is the easy part. I found I didn’t need tweezers. I just stuck the sharp end of a simple compass in one of the outer holes and managed to move the bayonet-mounted piece pretty easily. It popped right off.
The next step is the hard part, a yet-unsolved mystery. The Service Manual tells you how to do it but it’s difficult to grip lid 23 hard enough to expose both latches. I don’t want to force it with pliers. Tricks, anyone?
Most of the grilles are on too tight to just pop off, they require a distressing amount of force. Yours might have been opened before?
I don't remember... does the K601 also have a notch on the side by one of the tabs on part 23 that lets you use a small screwdriver to push it loose? Generally though, that part is largely about feel and can be a bit difficult if you don't want to use anything that might mark up the plastic, especially if you've never done it before. Doesn't help that the plastic is a bit stiffer on the K601/K701 than the older models, and is harder to flex it enough to come free.
