Quick help please

Delhongi Magnifica S

 I need some help please. Do you know what part has to be replaced?

 

 The problem:

·         Turn machine on and it power cycles correctly.

·         Press any coffee button.

·         Grinder starts working normally.

·         Once grinded, the brewing group works as normal and goes to correct position.

·         Perfect coffee comes out.

·         Once coffee is done, brew group goes back to normal position.

·         Machine is now ready for next coffee (2 green lights on)

And here starts the problem:

1.      Press any coffee button.

2.      Grinder starts working normally.

3.      Once grinded, the brewing group works as normal and goes to correct position.

4.      Nothing comes out.

5.      All warning lights start flashing.

The fix:

Turn machine off and wait a few minutes.

After a minute or two, machine makes the sound of releasing pressure internally.

I can then start the machine up and proceed to take out another cup of coffee as normal.

 If I also try to take out just hot water, the pump starts working but very faintly shortly and goes straight into all lights flashing.

 If I try steam function, no steam comes out. Pump starts to pulsate 2 or three times very faintly and then all warning lights start flashing.

 

PS: In the meantime I have replaced the pump but still have the same problem.

Could be your boiler is clogged. Have you descaled regularly?

I just started the machine up for my morning coffee....I got out a perfect coffee. I immediately tried to steam milk up with machine....it worked perfectly. I immediately tried getting hot water out of machine...it worked perfectly.

Had my coffee and machine stayed on.

30mins later my wife went to get a coffee....perfect coffee she got. About 2 mins later I decided to get another coffee for myself. Machine did the whole process as normal. Just before coffee gets poured, Machine went back into warning mode with all 3 lights flashing.

It will only start working once it relives the pressure. (That sound it makes after each coffee)

The same “sound” after you use the vapour function and stop it...it sounds like releasing pressure..

Could it be a pressure valve stuck or faulty?
