You have to replace the heater if the coffee is too cold or the flow is - mostly disturbed by limescale.

Pull out the power cord!
Remove the water tank and drainage tray.
Remove the side cover and remove the brewing unit.
Remove all coffee beans.

bei meiner Maschine muss ich die Schale 3-4 mal rausnehmen / einsetzten damit sich das Signal von „dauerhaft an“ auf „blinkend“ einstellt, deutet das daraufhin das der mikroschalter getauscht werden sollte. Übrigens, danke für das tolle Tutorial ..lg Tom

Problem ist behoben, Schalter getauscht, Position des Schalters ist bei der Caffeo Solo 950 sehr gut erreichbar. Alter Schalter konnte auch wieder gangfähig gemacht werden und dient nun als Ersatz.

Step 2

Unscrew and remove six Torx T10 on the rear.
Lever the rear cover off. It will most likely be quite stuck and you will need to apply some force. You must use plastic lever tools to prevent damaging the cover.

Step 3

Press carefully into the slits on the sides using a minus screwdriver or a flat metal spatula, to release the clasps on the upper surface. These may be well tight and you have to use some force.
You should have created a separation between the upper surface and side panels. Now lever the upper covering away using a plastic tool. This may be quite stuck and you may apply some force.

Translate

Step 4

Place a plastic tool in the crack between front panel and left side panel and widen it. Then push the side panel to the back. The side panel will be quite stuck and you may apply some force to do this.
Remove the hose from the water tank to the pump.
Remove the side panel.

Hi, I have a Melitta Caffeo Solo E950 and had a problem with the switch (it said that the drainage tray was always in while I removed it).

I was able to access the switch right after the step 4 behind the side panel.

The photo shows the old and the new heater next to each other. Mostly you have to transfer add-on parts (cable sleeve, screws, and clamping plates) from the old part to the new part.

Translate

Step 7

Unscrew three Torx T20 screws.
Remove the clamping plates of the thermal fuses and the grounding lug on the green/yellow cable.
The screws and the clamping plates must be transferred to the new part.
Carefully pull off the two flat plugs at the heater connection.
Later, also transfer the black rubber grommet - if present - at the heating connection to the new part.

Step 8

Loosen the retaining screw of the instantaneous water heater with a 4 mm Allen key.
The lock nut of the screw sits loosely in the black plastic housing and can fall away to the rear. If you pull on the screw while unscrewing it, this will not happen easily.
Carefully pull the thermoblock out to the front. Do not remove it completely yet, it is still connected to the thermosensor and the pressure hoses.

Translate

Step 9

Pull out the clips on the two pressure hoses and remove the two connections.
The two connections are sealed with an O-ring. Replace them during reassembly.

Translate

Step 10

Now the thermoblock is only attached to the thermosensor. Unscrew it with an open-end wrench SW8. Make sure that the fragile cables are not twisted and torn off.
