How old is your coffee maker?

Also do you have the user manual and do you descale the unit regularly?

Thank You,

My machine is approx 2 years old and in excellent condition. Clean, with no scaling or rust.

Hi do you Descale your unit on a regular basis?

Its a process you must do to keep the inner workings clean.

I need to know if you understand that so I can go further with you:-)

Its not a condition that affects the outside its an internal cleaning process.

If you would like more info on descaling please let me know.

I clearly understand the internal cleaning of the machine. The machine was de-scaled on a regular basis and all the heater elements, valves and pipes were tested for blockages and found to be clean. The water flows free during the rinsing process. But even during the rinsing process it reports that the grounds are to fine even set to max coarseness and no coffee is in the process,
