My Krups coffee maker Z2CF9031 began making cloudy, weak coffee. I cleaned it with a lime remover and it improved for 2 pots. I then had the same problem, so I doubled the strength of the cleaner and ran the cleaner through twice. Again, I had better coffee for 2 pots but then had the same problem. Please advise. Thanks.

Sounds like the thermal fuse (search this database under "fuse" and you'll find a discussion of it). I have yet to find the proper TORX security wrench, so I haven't been able to get to mine in order to try the things mentioned there, but I have a similar problem and what is said there makes sense.

Have you de-scaled and rinsed your Keurig?

Two things more you should look after: Boiling temperature and cleaning the funnel and exit needle.

Hi
Your brew head gasket is leaking and needs to be replaced. remove everything and turn the machine on its top. Look ate the brew head inside there is a black gasket and it should be clean and flat. If its cut or curled it needs to be replaced. Not cleaning the brew head will cause this gasket to be cut and after a while it will curl and not seal.
