| ***************Work in Progress**************** | | Before ordering the spares, check that your symptom is not simply a blocked filter or limescale. The instructions for cleaning the filters - particularly the boiler outlet filter under the overhang - can be seen at https://www.manuals.co.uk/delonghi/ec-220cd/manual. The boiler outlet filter requires a flat bladePhilips #2 screwdriver on a right angle rachet drive to remove. | | | The EC220 has been around quite a few years, and luckily contains no complex electronics. There are similar models still in production with, I suspect, minor changes. | | | It's relatively easy to replace the pump, providing that you use this guide. I spent several maddening hours before I worked out the right technique. The pump is located in the narrow part of the chassis, tied in with rubber brackets to reduce vibration. Replacing it does involve a complete disassembly, including removing the boiler and un-clicking the plastic sub-chassis inside the lid. | | It is also possible that the plastic 3-way (OVP) valve above the pump is faulty. This should be obvious from the noises coming from the pumpcan cause a reduction in pressure and leakage of water. | | | Before you start, make sure that the machine is absolutely emptied of water. If it gets over the electrics, it will be very hard to dry out and possibly trip your house electrics when you test it. Water will come out of the boiler when it is removed, so have cloths and sponges handy to mop this up - a surprising amount came out of mine. Make sure that nothing electrical is sitting on the workbench that could be deluged. | | | You'll need a long handled T20 torx security screwdriver - the plug in bits will not work as you need to reach down long and narrow holes. A magnetic version will be useful as the screws are hard to locate properly in reassembly. |
