DeLonghi PrimaDonna Elite ECAM650 Questions & Answers

I found out what is causing the tripping of the RCD. In the end I could not even make a coffee, even a black one. This was a year after my extended warranty ran out, so my machine is 4 years old. It's a PrimaDonna Elite 650. I pulled the sides of and long story short, the boiler has stainless steele flutes inserted into an alloy body. This alone causes corrosion with two separate metals being together under pressure and heat. It's a very bad design flaw. I spen 3200AUD on my machine and to only get 4 years out of it is outrageous to say the least. And this is a well known issue from what I can see on this forum. I've orded an OEM part that came from Italy and will not arrive until Jan 27th 2026, I orded it on December 23rd 2025. The issue of not completing the descaling began 2 years into owning the product. My water is a 1 on the hardness level and several measurements over the years proves that this has not changed in my area. But because the machine was still making all sorts of coffees with no issue, I thought it was power draw in an old house that was the issue. When the issue got worse in another old house we moved into I thought that was still the case. Old wiring and high draw. But when it started tripping the RCD (this is late last year, 2025, 4 years of ownership) when making a simple expresso, I had to check out what was going on. Corrosion on the boiler at the egress end due to mixed metals under high heat and pressure.

My model is a DeLonghi PrimaDonna Elite ECAM650.85.MS

I've spent 65aud to purchase the new boiler, but will only expect to get another 4 years at the most out of it. I will only descale with plain water as the citric acid used will only speed up the corrosion issue in the boiler.

Delonghi, You need to understand that you have a design flaw in these units using these boilers. Mixing metals in a high heat and pressure environment is metallurgy 101, and your designers should have known this. And if they didnt', you need to get a new team in.

You have sold us some very expensive coffee machines, only to find out that they lasted no longer than any other coffee machine, but with a hefty price tag that has only gone up in the last couple of years.

NOT HAPPY JAN!!!!

I will follow Patryk's question, yesterday I experienced the same problem. I hope that this time we will get quick help. Thanks

"Patrick 3y · PrimaDonna Elite ECAM650.85.MS I have gone through descaling process over 10times already, it just keeps repeating place 2l container under nozzle and water is finished. Water Hardness set and tried resetting machine up descaling never finishes. Always same thing. Delonghi what’s up with that? It won’t go past first step of descaling. Besides settings reset can we hard reset machine to read zero coffees etc?"

I have the same question. No matter what I do and how well I clean the machine the first thing it says when I turn it on "General alarm. Refer to user manual / coffee link app" How I reboot the machine it or go out of this message? The model is ECAM650.85.MS
