Sounds like your grind is way way to fine. Sloppy pucks are caused sometimes by water left on top of the puck that cant force its way through. As there is no 3 way valve on these machines the poor little pump will be running way over 9 bar and causing overectracted muck in the cup and it is most likely NOT a temperature thing.
1 Coursen up the grind and forget about the numbers.
2 weigh the dose if you have good scales or use your eye to try and repeat or change and improve.
3 good level tamp (hope you have a decent tamper?)
4 time the shots and look for signs of blonding etc.
change only one thing at a time and work on improvement. Good Luck. :)
