Seams that my saeco incanto deluxe has a problem with the brew group possibly the boiler the grounds come out dry. If I do a rinse cycle the water still flows help? How do I clean the boiler?

Your brew unit may be set in the wrong position inside the machine if someone has had it out to clean or try to fix. The unit has two positions open and neutral when putting back into the machine it should be neutral. This is something I would try first. Now if it is in the open position you will need to reset it. Resetting is better explained on video so I have put a link for a Youtube video. This guy is great and guides you through step by step. Hope this works for you good luck. Please post and let me know.
Cheers
How to Remove Stuck Brew Unit Q

Hi your brew unit is blocked. Open the service door and remove the brew unit and wash and rinse under water. Hot is better. The spout on the back side of the brew unit canbe unscrewed and cleaned. This is where most blockages are, Dazza REPAIRER

Could be your doser chute.

Check the bgrew group screen to see if they are clean and clear also under the top screen theres a small hole make sure that is clear also? Has the brew group ever been degreased this is if there is water coming out of the wand if no water there you have a internal blockage or pump problem

No it cannot. I am not sure why you would want the water hotter. It is designed to be at the perect temperature for passing through the brew group for coffee brewing, its kind of a simple science. 
If your machine has been producing less hot coffee gradually, that marks an issue. Try descaling the boiler per the manufacturer's inscrutions even if the warning light isnt on. The other option is that the thermal fuse mounted to the boiler is bad and turns off the boiler prematurely, those cost about $15 and are simple to replace. Lastly, the boiler heating element may be 'burnt out' new boiler is $120+

Are there any grounds in discharge tray and if yes are they wet or dry?
If they are dry then the machine has a water circuit problem. If they are wet then the brew unit is blocked or the grind settings need to be adjusted coarser.

Hi,

I think you have to replace the steam valve.

Have you descale your machine regulary?
How old is your machine?

Maybe your boiler have to be replaced:-(

Try descaling it manually- by adding the descaler into the tank, letting the machine warm up and then open the water spout to fill one cup at a time. wait 15min. in between. Also clean brew group and grinder.

Check the Pump to make sure you still hear the noise.If the water pump make noise nothing wrong with the pump.If you have hot water opening the steam knob the electro pump will be activate and this mean your pump is working and you problem could be in the boiler.Some times the Boiler get clogged in the little tube between the pump and the boilen entrance.Check also the micro filter in the brewing section.

After I posted this I decided to descale the machine again, even though I'd just done it a couple of weeks ago. After descaling and rinsing I tried running water through the brew group by pressing the pre-ground button, then holding down the big cup button. Still no water, but then I turned the little knob on the coffee dispenser counterclockwise, about half a turn. It worked! I rinsed it well, then made a cup of delicious espresso.
