Very wet grounds spilling into DeLonghi ESAM4200

For the last two weeks, the grounds have been very wet and spilling into the machine. There is no longer a solid puck anymore, but only muddy grounds. I have tried coarser (and finer) grind settings, various beans to water ratios, and multiple brands of beans. They have made virtually no difference. On top of the brew group, there is a flapper that ejects the spent grounds into the disposal. Ever since the grounds have been so wet, a lot of the muddy stuff sticks to the brew group, and some of it gets pushed in the opposite direction when the flapper swings back, spilling into the machine. I am comfortable replacing or repairing parts, but am trying to avoid replacing the wrong thing. I have made one prior repair to this machine, when the ball of the pump got stuck in the nozzle months ago. (I am re-posting this under ESAM3300, since the site did not recognize the ESAM4200 and put it in an overly generic category.)

SOURCE: Brewing System stuck

Hi, I think this is something I encountered once. Try this:
1. Shut the service door
2. unplug the machine, wait for any of the shut down noises to stop
3. plug the machine back in, wait for any noises to stop
4. check to see if everything is back in order

The most important thing is to keep the service door shut, and all the parts, ground basket, drip tray etc. in place. The mechanical will only operate with these things in place.

Hope this helps.

SOURCE: The grinder on my esam

The amount of coffee grounded is also propotional to the thickenss of grinds and the time. So when you udjust the grinding more fine then with the same grinding time the grounded coffee will be reduced. So if the grinding have changed to more coarse grindig that is why the quantity have increased.
Now their is a small posibility that the standard grinding timing to be increased but this can not be fixed since this is prefixed from the factory on the electronic board thus you will need a new electronic board.Of course the increse in time is due to only a tiny electronic part on the board called variable resistance you will need to replace the whole board to be fixed.
Therefore you can try to reduce the grinding step by step to more fine to see the results nad this might work bu 70%. However the coffee running time should by aprox 1 sec for one ml of coffee. So for one espresso of 30 ml then it should take about 30 sec to run.

SOURCE: I have an ESAM 5500

If you've tried the grinding adjustment knob while the mill is in operation with no effect then the chances are that the grinder has become dulled, usually caused by a foregin object within the beans. As these blades are supposed to last the lifetime of the machine they're not available as a replacement part.

If you have the technical ability you could try stripping the machine and looking for any obvious damage to the mill.

Remove the back panel to gain access to 4 corner screws that remove both side panels. Once these have been removed you've access to 4 corner screws that hold the top of the machine. You may also need to remove the 5 screws that hold coffee container in place, 4 are visible once the coffee beans container is open, but the 5th is hidden in the middle of the adjustment knob with a black cap on top. Use small sharp screwdriver to lift the cap and remove this screw. Now you can remove the top of the machine and then the coffee container too. This exposes the mill assembly. The top of the mill is loosely sitting in the lower part of mill and should be twisted to release. If it won't move then you may have to completely remove the mill and detach motor but this is quite obvious how to do.

Unplug it and try the following. See if there s a tab or lever than has dropped down in the track where the filter goes. This should push up thus allowing you to put the filter back in. Don't force it though. There is something physical in the way of this . Once you get it back in, the plug it back in. You will learn after you fix this what to do next time.

Delonghi coffee machine making an aweful noise,

Hi. Husband asks: When you first turn the machine on at the power point, does it make a motor sound and then stop, or is the awful noise apparent at that time.

If the awful noise starts as soon as you turn it on, then most likely there is a motor problem which will need to be seen by a Service Center.
