When I am pushing on the "pump" button, if the machine has not been used for 2 to 3 hours, it produces only hot air, then vapor, then water. The process can take up to 7 seconds. I DID NOT SEE THIS BEFORE.
I would suspect the pressostat adjustment. If the temperature in the boiler is higher than normal, water in the HX will vaporize more than before and you'd get that behaviour. Just guessing.
Also, beware the brita filter, if not changed on time, it could be worse than no filter at all. Maybe descaling again and making sure the filter is working correctly would be a good idea ?

It looks to me like the pump might be loosing its prime. I don't see any steam but it does take a few seconds for the water to start flowing and there should not be anything to stop the flow of water then when it does flow, it looks normal.

I agree it takes too long for the water to show up. The thing is less than a year old? Is it under warranty? I would let them fix it if it is under a year old.
