It sounds to me like you may have a clog in your generator or coffee boiler. It sits directly on top of the unit under your stainless steel plate. There is valving and tubing set up in it and they do tend to clog up over time from either scale or coffee grinds.

Unless the fill solenoid is already damaged, there is no need to remove it in order to fill the boiler. Install the pump, tighten the collar and start the machine as usual. If anything else is wrong, you will know within a few minutes. When the computer calls for the pump, it will automatically open the fill solenoid.

I have just had the same problem with my Krups XP7240 and I discovered (quite by accident!) that it was the magnetic float inside the water tank which was causing it. I think the float must have let some water in and always stayed on the bottom even when the tank was full. As the float was in an enclosed plastic column it was a bit hard to access, but through sheer desperation I snapped a plastic fork in half and wedged the handle section under the float to keep it off the bottom and this works nicely. It is not professional by any means but I was quite pleased with my innovation :)

The only down side to this 'method' is that the opposite is now true and when the tank is empty it doesn't register so you would really have to keep an eye on the water level to avoid killing the element completely.

I would imagine that the only professional way to get this sorted out is to replace the tank (or float if it is accessible?). Good luck!!

Couple of ideas.

Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").

Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.

The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.

If you have hard water that you are running through it, it will eventually slow down from build up. If your is just slow or has stopped all together what I did was cleaned my filter with vinegar. I then ran 3 brews through with straight hot water, did the trick and works like new...hope this helps!

It does depend on the machine. But often you just run some CLR or vinegar through it, then several cycle of water.

If you have a self fill cup you can, use that empty, and run CLR or vinegar through it, then several pure water through it.
Also there is this video.
