Hi
When you replace your heating element it is always best to remove one of the wire connectors to the heating terminals before filling the boiler. When the boiler is full you can then reattach the wire to the terminal. Always have the machine unplugged from the outet when working on the inside of the machine.
There is a reset button on the front side of the boiler. It is a red button between the 2 black wires on the high limit thermostat. If that didn't do it it might be the new element you just put in. Check and see if it will heat in the steam mode. If it will, its your brew thermostat.
Hi If you can get water from the wand with the middle switch, you have a bad steam thermostat. Its on top of the boiler and its the one that doesn't have the red dot on it. Replace the thermostat and you should be back in business.
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.
there are two class of expresso coffée: one produce crema and the other none. A 9 sec shot, means you are putting ground coffee that are way too coarse. The Silvia requires coffee grounf extremely fine, near powder texture.
Hope this help
Often these temperature differences are solved by descaling. Do never use vinegar. One can buy citric acid crystals or powder (not the same as lemon juice) and dissolve that chemical in water. I buy it in the Chinese Mall. Do not make a too strong acid. Shops sell maintenance powder which is the same but that is quite expensive. Let the acidic water go in and through the coffee maker until it looks clear. Next rinse with water for quite a number of runs. You may see how strong the citric acid that you make is by descaling something else and wait for about an hour. Another acid to be used in coffee makers is lactic acid. Lactic acid is bought as a cleaning agent. Also very strong and to be diluted with water.
It is most likely that something is blocking the pathway to the grinder. As the Rocky is a direct drive grinder there is no gear that could be broken.
Try to remove the beans from the hopper and inspect the pathway, move the beans that might be under the 'disk'. If that is not working you might have to open the grinder;
remove all coffee beans
unscrew the three screws in the bottom of the hopper
remove the hopper
Now you can see the grinder wheel and tell if it is turning normally.
This might be a good opportunity to give the grinder a thorough cleaning.
Do not soak it in water, just a stiff small brush (e.g. a toothbrush) is the best tool. And perhaps accompanied by a vacuum cleaner :)
If you have been using very 'oily' beans for a long time they might have clogged the grinding wheels.
Good luck,
