Here are the pictures of the screw I can’t get out and the boiler holder (holds the coffee filter).

I clean the diffuser and put it back and it’s seem problem .

Please help me out .

I am in UK and so the plug has the third earth pin.

The machine causes my RCD to trip due to earth leakage current when I turn it to heat the water. I read that with coffee machines this can be due to failed insulation on the boiler element, so I was going to take it apart and take a look.

Is there anything else I could profitably check whilst its all open? I notice that the terminals on the top of the boiler aren't fully protected. In fact from past experience opening the machine I think the terminals in mine don't even have those nice connectors like in the pictures.

I also read that blockage could be causing overheating. Would that be in the filter?

Would the fix for the element just be to buy a new one, or can something feasibly be done in a home workshop?

Thanks for reading!

My machine is turning on just fine, but it only releases very little (just dripping) water through the boiler outlet, even without the portafilter or any filter attached. Oftentimes on an immediate second attempt, no water comes out anymore. The steaming wand, however, is perfectly fine and with really good pressure, so I’m sure the pump is not broken. I’ve done all the troubleshooting I know: (1) water tank is full; (2) already descaled through the steaming wand; (3) already cleaned the boiler filter and the spring-and-ball inside. I also attempted descaling through the boiler, but no water comes out even after 10-15 minutes with the pump on.

I would get coffee from the machine after a few minutes of no usage, but it drips really, really slowly unlike what I observed in YouTube videos. And I’m not even sure if it’s espresso I’m getting from then. I took a video of it in action for you to better understand what I mean: https://photos.app.goo.gl/ac6KFbmnCGpvzJ...

EDIT: I already figured it out. The spring inside the boiler outlet is a bit too stretched, thus creating an overly tight seal that prevents good flow of hot water. I compressed the spring a little and loosened the flatheat piece, and now it’s working fine.

I opened it and change a thermostat that looked like it was bad, after a while the water flow started to decrease until I got the same issue again and got a new coffee maker.

Now I have the DeLonghi EC3240 and after a year and a half I am having the same issue with the lights again.

Is this is a known issue of DeLonghi coffee makers or is it an indication that something else is going on?

Thanks!

my ECP 3420 espresso machine is leaking water above the Group Head. I have opened and cleaned the springs, descaled the machine but still have the issue continuing. can someone please guide

The heated LED never turns green and the water coming out is consistently cold. I’ve checked both thermostats and they are currently working. What are other things that I could look into? Thanks for the advice!
