My Miele steam over keeps telling me to insert fresh water which I have done in the plastic water bucket / container that they provide..... the warming light refuses to go away....Any tips on how to fix it?

My Miele was stuck in a loop repeatedly asking for more water, and then I got it stuck in a descale loop. I called Miele to ask them how to 'reboot' the factory settings, but all they would suggest is me booking a visit from an engineer. Expensive and pointless.

However, I then managed to find a video of someone entering the hidden Programming Mode for another model, and the same button combination worked for me.

Press and hold the timer button (the one with a bell picture on it) and then press and hold the power button at the same time, and let go of both together at the same time.

Then press the timer button alone 5 more times, and on the 5th press, hold for a few seconds. From there I played around with a few options until I found one that reset and restarted the descaling. I've linked to the video where he enters Programming mode after 2 minute mark.
