Machine constantly saying "clean now" even directly after a cleaning

I stumbled on what could be a solution. It worked for me.
The "Clean Milk Pipework" maintenance cycle expects 300mL of lukewarm water and a cleaning stick.
There is a step in the cleaning routine where the pump keeps going, even when the water dispenser is empty.
If there is too much water to start with in the dispenser, the routine cannot complete all its steps, and the machine gives the "Clean Pipework Again" message.
So the fix is rather simple. Start with 300mL of lukewarm liquid (and a cleaning stick if you like I guess, but I didn't use one) and follow all the steps to complete the maintenance routine.
It sounds like the Miele machines get absolutely locked into their cleaning routines, and you can't get control of the machine back until the routine runs to completion.
good luck.

try to send it a service man, and see if it really the lens..

Is it a mechanical (NOT computerized), has it been cleaned and oiled recently? If not, the old oil will turn to glue and stick the moving parts together. Consult your owner's manual under the Maintenance section, use good quality sewing machine oil, and apply only 1-2 drops of oil each spot as indicated in the directions. Gently hand rotate until things loosen. To help speed things up, you can direct hot air from a handheld hairdryer into the internal mechanics.

To keep your machine working, be sure to clean and oil every time you change a bobbin, every 8 hours of constant sewing, or every 6 months if it is not in regular use.

Is it a mechanical (NOT computerized) machine? If so, your machine probably hasn't been cleaned and oiled and the selector mechanics are stuck. Consult your owner's manual, clean and oil as directed using only good quality sewing machine oil and apply only 1-2 drops of oil each place.

Try this ONLY IF IT IS A MECHANICAL MACHINE: gently try to move the selector bar and see where things should move and apply a drop of oil. Then direct hot air from a handheld hairdryer into the mechanics and see if that helps free things up. You may have to repeat multiple times.

Once it is working again, clean and oil every time you change a bobbin, every 8 hours of constant sewing, or every 6 months if not in regular use.

Sewing machines need to be worked periodically even if you aren't sewing a lot. The oils and greases inside get all gummed up and literally will seize them up. Your best bet is to take it to the pro, pay the $$$ and have them, clean, oil, grease, replace belts, and adjust. OR if you want to give it a try.. DIY... kerosene based cleaner. Clean it well, then oil it properly. Make sure the machine is UNPLUGGED while cleaning.
