Posted Sat Jul 20, 2013, 5:02pm Subject: Repair/Upgrade a Capresso EC100
About 4 months ago I got a refurbished Capresso EC100. It has been working fairly well, but never liked the tank to be too empty. Recently, it will not pump unless the tank is full. The Capresso rep recommended decaslcifying, which I will do but doubt that is the problem. I have found an Ulka EAX5 pump for $35, which I believe to be an upgrade over the EA5 that it comes with. So I am planning on doing the repair myself, rather than spend the same money on shipping and getting back the weak OEM pump.
Question is, is this the best way to go? Is there a better pump to use? Any advice before I proceed?
I know it is not a popular model, but when it was working well it produced fantastic espresso. I am also of the belief that that pump could be used in a Starbucks Barista, if I chose to go that route later. So no loss in attempting the repair.

I could not find the plain EA5 but EAX and EAP with X having a metal outlet. EX is for hot water, or either. Better, not so sure, perhaps the same pump different outlet?? Here is the site with watts and flow.
I would probably start with de-scale and see where it leads. If it has been a long time, the first de-scale may only be the start. Sometimes you loosen particles and need a couple attempts, or more. If the refurb included a de-scaled clean machine then 4 months is not so long, but it depends on water hardness.
I believe the boiler is stainless?? You have a lot of choices from citric acid, acetic acid - I do not like the smell, and prepared such as Dezcal, Durgol, Saeco ... , but not CLR. You might try to find what is available locally.
