capacity - did not know that

MKS

condensers also age.
Machine runs like new again - THANK YOU for

Hi, I bought the DeLonghi 685.
The 2 lamps for
the cups
flash with me
after the foaming. The

manual states that the lever

for the nozzle is not set to 0. The lever is at 0,
but when I let off the steam, the two buttons
stop flashing. That's what

happens

when you press

a cup button under the foam

.

Then all that comes out is hot water and no

more steam.
Shouldn't the excess pressure be released automatically
when you set it
to 0
?

Hello,
I am only writing here because I had the same problem and wanted to tell you what was going on with me. Maybe it helps someone.

Symptoms:
Switching on, machine "warms up" so the power button flashes slowly for about 2-3 minutes. The two coffee buttons then flash quickly back and forth as described above. Nothing works anymore.

Diagnosis:
What I found very helpful was the hints from "Frahlingliebhaber" to press and hold both keys and then switch on the machine. After approx. 5 seconds, the machine allows water to run through for a further 5 seconds. So on the one hand (in an admittedly arduous mode) you could do a decalcification, but that wasn't my problem. On the other hand, what you can determine very well with it is whether the heating still works. So: Switch on once as normal and wait until the 2-3 minute "heating phase" is over and the keys flash alternately. Then switch off again, keep both keys pressed and switch on again. Wait until the water comes and check if it is cold or hot. I was cold. That means the heater's not working. Therefore, the coffee machine has also signalled an error (= alternating flashing), because after several minutes it "heat up" runs into a timeout and then gets "still cold" signaled by the sensor.
This can have two main causes: 1. The desoldering fuse on the thermoblock has melted through. 2. The switching relay is broken. Both can be checked with a multimeter when the machine is screwed on. This is somewhat difficult to achieve as Nespresso has kindly installed screws with special heads. A little pliers will help. Then it is best to screw in normal screws (the normal device screws for flush-mounted sockets of the electrical installation (3.2 x 15) work quite well here).
In my case it was the relay. If this is the case, the diagnosis can also be carried out more easily: Normally you can hear the relay switch clearly after switching on in the warm-up phase. I didn't hear anything more about me.

Therapy:
In my case: Replace relay. This is a bit hard to get part, but I bought another one from Conrad (of course it has to fit regarding voltage and current and should fit halfway) and soldered it in with wires, because it didn't fit directly on the PCB. After that everything went fine again :-).

All in all it took about 2 hours (without the time to get the relay, but including the whole troubleshooting) and left the good feeling of having repaired something instead of throwing it away. :-)



Hoffe this helps somebody,
Sven

P.S. If it was your desoldering fuse and not the relay, I would be careful with repairing it. This would mean that it has become too hot (it sits directly on the thermoblock). Since this can happen again at any time, I would first look for the cause for it (defective temperature sensor, etc.). Otherwise the device might really burn down...

men idont now how to thank you friend

my la cube back to normal again

I would also appreciate any advice on which relay to buy from Conrad to fit in the Le Cube!

It's been a while since I asked this question, but others may still find an answer helpful.

Originally, my Krups Nespresso Le Cube XN 5000 had the Hongfa HF3FD-1/048-HS3F subminiature relay installed.

I used a Zettler AZ943-1CH-48DE as a replacement, but it's only Class B instead of F (only 70 °C instead of 85 °C max. ambient temperature in operation); it's a toggle switch, but you can simply bend the superfluous second contact over before soldering it in.

The replacement relay is available at Conrad or Voelkner ( cheaper shipping) for 1,80 € + shipping (as of May 2015).

When disassembling and reassembling, this service manual helped sufficiently well.

Been a very-very long time, but....
Would this product also fit (also at Contad)?
Finder 36.11.9.048.4011 Print Relay 48 V/DC 10 A 1Max.

Temperature is here 85°Thanks

& GreetingsBoris






Did it work for you with this relay?

hello, 90% relay is defective. 10A 48V and must not be original .I have a thick relay put aside minus and heating with 1.5mm and switch inputs with thin wire soldered and insulated works perfectly . Relay from 30v is enough but amps must be +10a.have fun.

hello thank you

can you please send me an example of relay that can replace the original and also the scheme, how did you connect it?

How did you soldered the Zettler AZ943-1CH-48DE on the circuit board?

can you please show a diagram

I found the orignal relay on ebay from a seller, it took me a few days but in the end I contacted some ebay Chinese sellers and one of them had this relay @ 48V and he listed it on ebay

Hello

Can be that the control is stuck in the decalcification program.
Since only perseverance helps. smile.gif
Hold both buttons and turn on after 10 seconds release buttons then just leave on for an hour or longer. Try this several times. Then disconnect from the mains again for an hour.
At some point the blinking frequency is lower (machine heats up) and then both lamps stay on constantly (standby).
I have already revived a Citiz in this way, it took 4 hours. You can disregard the lever that is not queried.




Thank you, my 12 year old Cube was stuck in descaling mode. This answer seemed to me the closest, it worked, already in the first run, now's first an espresso smile.gifsmile.gif

Tried and true solutions are the best - it worked!!! I was already full of grief and on the verge of unscrewing.... Electronics failure on mine too - and I suspect a sudden long power outage messed up the electronics.
Thanks! wub.gif

Hello,
Please note that the small cup / large cup buttons flashing for some time after power-up does not necessarily mean that the machine requires descaling.
In my case, after power-up => no heating at the boiler => machine goes into fault mode with small cup / large cup buttons flashing.
Diagnosis = heating relay coil on electronic board out of order (HF3FD-1 048-HS3F) replaced by FINDER relay 36.11.9.048.4001 ordered from Conrad, => after this troubleshooting machine OK
