We have owned an Isomac Millenium for ~2y.
In the first months, we encountered low water to the brew head, although both the steam and hot water wands had decent pressure and flows.
Adjusting our grind, so that the coffee beans were coarser helped immensely--for awhile.
Then the problem gradually reappeared as an extremely slow brew time. Our machine was still relatively new, so we shipped it back to our place of purchase. It came back working just great and interestingly the filter in the resovoir was now filled with the filtering particulate it did not come with.
I am surmising, that however great the engineering is on the Isomac, manufacturing leaves something to be desired. Do not let your warranty expire. Pay the shipping and fix your otherwise great machine.

General descaling will work for a while, but after some time, you'll get the temperature problem worse and worse.
I had a problem with my Pavoni 16 lever not being hot enough, and so not having enough steam pressure. The solution was to clear the lime deposits from the thermostat. When I did that, the temperature and pressure shot back up.
The thermostat is in the base of the machine, and it's at the end of a blind tube coming from the base of the boiler. So even if you regularly boil up the machine with vinegar, the end of that blind tube doesn't really get cleaned, and it fills up with lime. When that happens, the thermostat isn't able to properly sense the temperature of water in the boiler.
You can fix this without opening the boiler. Remove the base of the machine, and separate the thermostat from the pipe that connects it to the boiler by undoing the plumbing connection. Disconnect the electrics from the thermostat and fill its sensor end with hot vinegar, then flush and refill a couple of times to get it really clean. Poke a long flexible object, like a pipe cleaner or cable tie, up the short bent pipe that connects the thermostat to the boiler, while dribbling some hot vinegar down the pipe. Reconnect the thermostat to the pipe and do 3 boil flushes of the machine with clean water.
You can see the tube in photo #36 of my Pavoni rebuild at http://cid-e0a4d8901828b395.space...A4D8901828B395!166
Hopefully this will get your machine back to making great coffee!

Sounds like the handle where you put the coffee in needs replacement, if you leave the machine on for long periods with the handle on there is a metal spring inside with plastic parts that regulate the pressure in the tamping basket. 9 BAR is the desired pressure to produce crema. the plastic parts can melt and the spring looses tension. If you place the handle on, lock it, the it should shift slightly backwards on its own if you have to help it I have bad news replacement time. I have seen replacement from 25.00 - 90.00. I have two classicos and already replaced one handle and have to do the next. It could take one time of leaving the machine on all day. Good to get in habbit of turning off the machine immediately after use let it cool slowly attached to unit and clean it when you get home. Immediate cleaining in cold water could make the spring fatigue faster and also cause this problem.
If you are brave and can remember where parts were; take the three screws off where the coffee comes from handle slowly separate the parts and you will see if plastic melted, is distorted or spring is like mush.
Here is the saeco parts diagram and parts ordering site but I warn you its the most expensive

Are you getting enough atmospheric bars of pressure? Should be around 9 or so. if not that may be your problem... also if your portafilter is pressurized (there will be a plastic disc under the screen) try removing it and see if you are getting crema then... Helped alot with mine. I also shaved the bottom to make it bottomless but that may be alot further than you want to go.
