For the hard to fix try this before chucking.
I did 4 x the recommended vinegar method. Took it out back and shook the crap out of it. No go.
I took the bottom 5 screws out to see what was up. Nothing to report.
Took the top moveable handle off, 2 screws. Inside is the hoses, too thick to be blocked.
The needle where you are supposed to clean from outside with a paperclip is here.
When following the waterfow to the needle that pierces the k kup there is a wider 3 q inch tube right before the needle outlet. This has a fine screen ish in it. Clean that. There is a bunch of of "ggrrrr" involved but a ten minute job. I was close to buying new. Take it apart and you will see what I did.
I have a pic but do not know how to get it from my samund tablet.
Paperclip will not fix this, takeapart will.
