No coffee from philips Ep4051
Posted by: Caro13neu April 11, 2023 09:32 pm
Good evening,
I did my normal routine cleaning today including brew group. After restart wanted to bleed the system. I also did that. Afterwards, no more water came out of the coffee outlet during the system flush. When pulling coffee, the machine starts to get quieter and quieter and then breaks off, the brew group then makes a very loud noise. I hope someone can help me quickly.

Hello, when the pump becomes quieter, it pumps against a resistance.
Think times that the brewing unit is clogged. Brewing sieve or crema valve are often the cause.

Hello, thanks for the reply. Took the machine apart today. Coffee outlet cleaned, igitt (vorallem inside), valve checked, sieve brew group cleaned. Tried to descale. No coffee comes out, pump keeps going quiet, brew group goes into position and then pops back with pressure. Then the machine jumps into deaeration mode. Can the brew group be defective? But I have the feeling that the water does not reach the brew group.

Hi Caro, what do you normally descale with?
I suspect that the boiler has become clogged with lime.

Hello MrLed, I always descale with durgol, have aquaclean, but still descale in between. Should not, when the boiler clogged first little and then no more coffee come? Until yesterday, however, the coffee ran at full pressure. Hot water continues to run very quickly.

Surely this can also be related to the brewing unit.
Remove the crema valve that is under the brewing sieve. Then run through again.
If that does not help: I think the ceramic / multifunction valve does not work cleanly.
Is possibly the driver defective. For these valves, the distributor head is crucial, the other is only the plugs. So with a little skill can be modeln that around.

Thanks for the reply. Have tried today times another brew group. The machine then runs through without that it is quieter, also no longer wants to be vented, but coffee it still does not want to output, the water ends up in the drip tray. Einleuchten hissing is heard during preparation. Where can I find the ceramic / multifunction valve?

Hello, for this you need to open the coffee machine, instructions can be found on the WWW or in the large video portal.
But first remove the drip tray and bypass the microswitch for this. Cardboard strip or wooden skewer and see where the water comes from that flows in the drip tray.

Hello, it seems that your coffee machine is having a problem with the water flow. It is possible that air was trapped in the system during the purge, which is preventing the water from flowing properly. Here are some steps you can take to solve the problem:
Check the machine's water tank and make sure it is filled with clean water. If the water level is low, the machine will not be able to work properly.
Try to purge the air from the machine again following the instructions in the user's manual.
If the machine continues to make a very loud noise and stop when making coffee, the brew group may be blocked. Try removing the brew group and cleaning it thoroughly. Make sure all parts are back in place before restarting the machine.
If none of these steps solve the problem, your coffee machine may have a more serious mechanical problem. In this case, it would be best to contact your manufacturer's service department for assistance.
Hopefully this will help you solve your problem.
