DeLonghi ESAM xxxx - (Different Types): Delonghi ESAM4200S stuck on red triangle when power on

Sat, 16 Nov 2024 17:51:32 -0700

Hello, I have a Delonghi ESAM4200s with the red triangle led that lights up and stays on when I switch on. (Sometimes, 1 cup and 2 cups leds are on too).

I used the test mode (press and hold 1 cup + steam and switch on), everything worked perfectly except the thermoblock. No led turns on when I pushed the « Rinse » button, it doesn't heat up. So I checked its resistance and it was good (38ohms). The thermofuses are good too. The thermosensor is good too (10kohms). I tried replacing the power supply board and nothing changed. I checked the all switches and all works fine.

Do you have any advice on what I should check?

De'Longhi EC155: Cleaning the boiler outlet

Sun, 27 Feb 2022 22:04:19 -0700

I can’t get the screw out to clean the boiler outlet. It seems to be welded in. Water won’t pump through. Do I have to throw the whole machine away because the screw won’t come out?

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

DeLonghi ESAM xxxx - (Different Types): water comes from steam wand not coffee spout

Sun, 14 Jan 2024 23:14:01 -0700

Hello, our DeLonghi Magnifica ESAM3300 does not discharge water from the coffee spouts. Instead, the water comes out of the steam wand. Happens even on self-clean cycle when turned on. Coffee spouts are not blocked the infuser cleaned and the machine descaled. Is it the end? Any suggestion?

When i push the button to make espresso on my 3 year old Delonghi 3300, water sometimes comes out of the frothing wand instead of espresso. It does not do this all the time, just periodically. I have checked hoses for blockage and replaced O rings.

DeLonghi Coffee Maker: My Delonghi EC260 is leaking water from under the water tank

Fri, 22 Dec 2023 20:06:55 -0700

Hi, my espresso machine is suddenly leaking water from the base, underneath the water tank. I descaled it & that didn’t help. There are no cracks in the tank and the seal looks good. But I have noticed that the plug inside gets pushed up…water going out…when I put it in the machine. I think it’s only supposed to do that when it’s running but don’t really know. I have to put towels down when I use it now, so water doesn’t go all over the counter. Help!

DeLonghi Coffee Maker: DeLonghi Magnifica: no water coming through

Tue, 07 Feb 2023 20:33:38 -0700

Hi everyone,

I got a DeLonghi Magnifica 2 months ago, used it for about 1 week, then emptied and cleaned the tray and left the machine for 6 weeks or so.

When I turn on the machine now, there is never any water coming through, neither upon start-up nor when I press a button. Instead, the water light starts blinking (the reservoir is full). According to the instructions, this indicates too fine a grind. I initially thought the grinder needs to be cleaned, but the machine does push ground coffee through into the tray whenever I press the button, and there is no water when I turn the machine on either, so it seems water-related to me.

Does anyone know what this could be? I thought I might need to descale the machine, but it seems like there is a separate light to indicate that, and since I only had the machine for 2 months and used it for only 1 week, that seems unlikely to me.

Thanks!

DeLonghi ESAM xxxx - (Different Types): Delonghi Caffe Corso Flashing Water Tank Error

Fri, 03 Feb 2023 04:12:09 -0700

Hello, my Caffe Corso worked fine until a few weeks ago when it stopped making coffee. I took the entire thing apart water pipes, pump, valve etc. and found the primary issue - a huge rock of limescale clogging one of the smaller pipes - and removed it. Water now flows, however, only for circa 10 seconds and suddenly it cuts out with the water tank light flashing. I can try again and it will work but again, only for circa 10 seconds. Does anyone have any ideas aside from the usual one of turning the steam nob because this only works for 10 seconds too. For the same reason, it cannot be properly descaled, although I've manually ran this. Thanks!

DeLonghi Coffee Maker: Delonghi EC820.B water runs thru diffuser w/o the sump but no coffee

Wed, 07 Dec 2022 15:24:15 -0700

Hi there, hope you can help!

I have a Delonghi EC820.B coffee machine.

All of a sudden, my machine has stopped working. Without the sump on, water runs out through the diffuser quite nicely. But whenever I put on the sump with a filter engaged (correctly), water only collects in the filter and doesn't pass through. This is the same whether there's coffee in the filter or not. When I remove the sump, the air pops and a little steam puffs out, suggesting there's good pressure in there. Coffee is wet through.

When switching on to feed water through, it's loud as normal for the first two seconds but then subdues to a quieter, duller hum than usual.

Something about this suggests pressure to me. I have cleaned all the parts I can reasonably get my hands on - the filters were working well, flow was good and then NOTHING, rather than progressively becoming more of a dribble so I figure that's unlikely to be the problem.

Reservoir is full. Steamer passes both water and steam. I have not changed the coffee I have been using all this time with success.

Any help would be warmly received - I'd rather make do and mend in this case!

Thanks in advance.

DeLonghi ESAM xxxx - (Different Types): No hot water and steam comes out.

Thu, 08 Feb 2018 09:51:25 -0700

Hi. I have Delonghi ESAM 04.350 bean to cup coffee machine.

- The Machine's steam function (and hot water) function is not working. I just hear 'click' noise when I try to get hot water but nothing comes out.

- When I push the hor water or cappucino button, there is no warning on the screen, but there is "heating" shows up and dissepears in a second (It should be "preparing hot water/cappucino) . It seems like something wrong with electronics.

+ When I'm using 'descale' function, hot water comes out and the machine descales normally.

+ Espresso part is ok

+ Cup heater is working properly

+ Any other functions seems working

What can I do to fix this problem? Thanks.
