I have a 4 year Old Rancilio Silva machine that stopped pumping water. I looked up the problem online and sounded like I needed to replace the pump. I ordered it here and from online guides was able to replace the pump myself!! Works great now and I only had to pay for the price of the pump!! I am not mechanical, so this made me pretty happy. Please note, it does not come with instructions on how to replace the pump in your machine. Also, I did need to add some tape to the threading when it was replaced because I had some water leakage after replacing part. Good luck!!
Espresso Parts is a fantastic resource for espresso enthusiasts. Machines are expensive; repair is the way to go! I had a no hassle experience. I ordered the wrong part (because I don't know what I am doing). Realizing this error, I returned the party with no problem. Then they set out the vibratory pump. It was an easy install (use plumbers tape on the connection to the hose that feeds the boiler). thanks Espresso Parts!!!!!! Ken
