Done successfully. Note that it is not an 18mm nut for the steam connection. The correct size is 17mm. If you look closely in the picture, the 18mm wrench is fairly loose on the nut.

It is a 17mm nut, correct

I’m having trouble getting the valve to come out. It’s really stuck ! We’ve used a lot of pressure and it’s not even wiggly .

The valve screws are no problem and do not break, but the valve itself is usually stuck in its "hole in the boiler".
Remove knob as described and use the 17mm open wrench to put on top the valve end after plastic guard towards the boiler.
Then use another heavy wrench (e.g. 19mm) or hammer to hammer the the valve from left to right and back from right to left.
This takes time and makes a loud noise, do not hammer on the valve direct, use the 17mm wrench to transport the force only from side to side.
Once the valve is moving put a screwdriver (or something similar) unter the valve between the boiler to ramp up the valve slowly (1mm per left-right-left turn is enough). Take your time, in about 10min you see the valve getting loose more and more and at the end you can lift it up.

my challenge is that the stam knob is not reattaching easily. i have the metal on the round part when i push. It stays on but a big gap to the chassis, and falls off easily. Any ideas?
