If you are looking for steps to fix this, you are at the right place!
Please follow these steps:
Decouple 2 parts. The second last part is the filter. This one should be left until dry before being recycled. Keep the first part.
Find a new filter somewhere on the shelves.
Pour water inside the tank, plug it back into the machine.
It should show 'filter is being rinsed' like this.
