I recently cleaned my rancilio silvia by backflushing. However, I forgot to flush the system afterwards (the boiler was on) and I think the cleaning powder has baked somewhere and caused a blockage because no water comes through the group head. I can get water out the steam wand OK. Is there a product that will dissolve? Not sure just descaling will work because there isn't an end to end flow. Anybody got any suggestions how I can remedy short of taking the think apart?
Hi
More than likely your 3 way valve is stuck. It is located behind the front panel and when the 2 screws are removed it slides to the right. Unplug your machine before working on it. The 3 way valve is on the left and you can remove the dispersion tube on the bottom(unscrews) 14mm nut holds the solenoid on and you can slide the solenoid down the shaft. The big nut at the top of the shaft will unscrew and there you will fin the solenoid inside with a big spring. If its not stuck it will slide out and you probably need a new 3 way valve, but more than likely its stuck. Some times just tapping the nut on something hard will unstick the solenoid. Clean good and reinstall.

I have the same problem although it was not caused by backflushing as I have never backflushed my machine. When you turn on the brew switch, the water gets sucked in the inlet pipe but get pumped straight back out the outlet pipe back into the water tank. No water is coming out the group head.
