It's certain.  After many descaling attempts, my EC155 can't pull a trouble free shot.  It seems to have gotten weaker in delivering the water and additionally, I'm having a hard time getting the green light to stay on for a full pull.  When the green light goes off in the middle of a pull, the pump shuts off until it comes on again... effectively ruining my shot.

The best I can do is about 15s worth of green light and that's after running water through several times and standing ready to pull the second the light comes back on.

I purchased the machine in May '13.  I suppose the next step is to call DeLonghi.  Any experiences out there, with this?

UPDATE: sigh.  I've been using an unpressurized basket.  I put the pressurized double shot basket back in and it stayed green the entire time.  It seems, though, that it used to do a better job with the unpressurized basket.

I know... "buy a better machine."  I wish I could right now.

Did you use an actual descaling agent? Machines like this aren't meant to be descaled like a regular espresso machine.   The descale may have damaged the internals.  Cafiza also shouldn't be used inside but it's great to clean the baskets. Also you want the boiler to kick back in sooner rather than later.  Once cold water from the tank goes into the boiler it starts cooling the hot water inside.  My old Delonghi would usually kick back in once I got about 15 sec into a shot with the unpressurized basket. I would run 2-3 full tanks of water through the machine, group and steam to clear out anything left behind from the descale.  If water delivery is the same without any coffee in the portailfter then water flow isn't a problem.  Just adjust your grind/ tamp.  If you try pulling a shot and it's tasty and hot then your machine is still ok. :) If water delivery is slow with no coffee you may have harmed the pump. If the temp is cool you may have damaged the element.  


If you wanna descale the Delonghi, your only option is to tear it apart and soak the boiler and element in 50/50 vinegar water.
Id your Delonghi is damaged look around on Ebay or buy a new one.  For $100 tho you get what you get.  

Bottom line If you get hot water with regular even flow from the grouphead your good to go.

Agree with Burners post above.

Also I had a Bar32 (same internally as EC155) that started having trouble and went, didn't even bother with Delonghi for warranty as dealing with them makes you want to pull your hair out, and these machines are unfortunately junkers once they start having issues. There's no parts or anything you can buy to service them, they go, you throw them out. If you bought from a retail store you could try through them to get a replacement since you just bought a few months ago. I don't think there's any manuals or anything for these machines, and they use odd screws, I had to go buy some long torx (or something else, forgetting) and it's a pain in the ass to take apart, I just did for the hell of it since it broke and you almost can't get it apart w/o plastic breaking lol.

If it is busted or well just cause I'd look at getting one of these.  You will get a better shot.

If your pump is shutting off like that during a pull, I would think that the pump is on it's way out.  I'm not 100% sure but I think these machines use Ulka pumps, which aren't exactly cheap but are usually quite durable.  I have descaled my old Ec155 in the past and have done it in the same manner I do on my Lelit which is a very similar machine internally.  I always made sure that I only used cold water in the reservoir as hot water can ruin the pump.

With that said, if it does require a pump replacement the cost wouldn't be that far off from buying a brand new EC155.  For what it's worth, I think they are good value and can make a great shot if unpressurized.

Thanks.  I'm back to using the pressurized basket and it's giving me something drinkable, though not great.  At this point, I'm leaning towards trying to figure out how to get $200 together.  Whole Latte Love has the Gaggia Baby, refurbished.  We just ordered one at work, so I'll be able to check it out.

Maybe I'll try to get DeLonghi to fix it since it's under a year.

Not bad for a Gaggia.  For fixing the Delonghi they may tell you they won't bcause you cleaned with descaling agent, goes against the warrenty.

It appears that the Gaggia Classic and the Gaggia Baby are the same machine, internally.  Sorry for going off topic.
