Product review (5 stars): Do it yourself replacement of flowmeter
This was a replacement part for my DeLonghi EC860,Automatic Cappuccino Machine. My husband and I replaced this flowmeter ourselves, but I will warn you, Before attempting to replace make sure you have the proper tools to open the case, and also go over to youtube and find the video that will show you how to  open the case and replace the flowmeter. (1) tool to use: purchase "Carlyle S14T20H Tamper Proof Star Bit Socket. from NAPA store. cost is $9.00.  We did not buy the right size the first time and had to go back until we had the right size socket, these screws are very small and are designed to be Tamper Proof. Our machine was not in warrenty. (2) watching the repair of Flowmeter on YouTube make id quit easy to understand how to take off the cover, where the flowmeter was located and putting it back together..  We are now enjoying our Cappuccino again.  Good luck
