This is not a fault
The cleaning cartridge has been removed. If you remove the cleaning cartridge, the cleaning line will also be rinsed the next time the coffee machine is switched off.
The cleaning line rinsing process can take up to 5 minutes.
Wait until the rinsing process is finished. The coffee machine will switch itself off.
Do not switch the coffee machine off before the Rinse program has finished; otherwise, the coffee machine will start the Rinse program again.
