Espresso: DeLonghi EC155

Hi,

I am new to this forum. I have had a DeLonghi EC155 machine for the past 4 years. Has worked fine, but every now and then the flow stops due to some kind of clogging, but will resume automatically on its own after some time. Today, the flow never resumed so  I cleaned the metal filters (both in the unit as well as the basket) with a toothbrush and also by showing them over a flame. But it didn't really help. Even when I held up the filters against light, the holes were visible and not clogged. After scratching my head, what I instead found is that, in the basket, there is a plastic disc below the metal filter which channels the coffee through a hole in its middle. There is a thin rod going through the hole, which seems like metal, but I am not sure. It doesn't seem like there is a way to remove this rod, but I managed to turn it a few times by gripping it with pliers. After this step, the flow definitely has improved. I think that coffee grounds or mineral deposits somehow accumulate in the minute gap between the rod and the hole, and there doesn't seem any way to clean these surfaces. Am I correct in my observation? What is the best way to clean this? Thanks.

Welcome to CG.  

There are many cleaning solutions for espresso machines that seem to help remove residue.  

There is a fair amount of information here on CG if you search "ec155" with depressurize or basket.  This may get you started until others with EC155 chime in.

You are describing the basket pressurization system.

I own the same machine and depressurized the baskets a long time ago.  If you own a good espresso grinder then you’re in luck.  Once you remove the plastic disk you now have a depressurized basket.  Keep in mind that all Delonghi Bar and Breville baskets prior to 2012 fit the EC155.

I would run water through a full reservoir of water before you attempt to pull a shot just to see if your pump is shot.  4 years is a long life for a $100 machine.
