You can replace them but unlikely to repair them. The casing will come apart, with some difficulty.
Remove the old switch, source an identical new switch and fit it.
The milk delivery tube is very narrow bore and in my experience you will find the tube is blocked with congealed milk solids even if you clean then regularly. You need an enzyme milk cleaner like Rinza and even with that you need to manually massage the tubes or remove the blockages. The service engineers just replace them.
That .depends on software and configuration. It is not a universal code You might find help in the manual. CIMBALI M34 SELECTRON USE AND INSTALLATION Pdf Download ' ManualsLib
Inspect Electrical Supply: Ensure that the machine is receiving proper electrical power. Sometimes, an interruption in the power supply can trigger error codes.
Clean Components: Check if any components related to coffee grounds or filters are dirty or clogged. Clean the underpan gasket, filter holes, and filter holder outlet hole.
Coffee Ground Quality: Verify that the coffee grounds are of the correct consistency. If they are too coarse or too old, it can affect the machine's operation.
Discharge System: Examine the discharge system for any blockages.
The K111 coffee maker's red light typically indicates it's in the heating process. When ready, the light may change to green. The green line with ** suggests that it's in the brewing stage. If there's no water flow through the pod and it's noisy, check if the water reservoir is properly filled and securely placed. If the issue persists, consider contacting the manufacturer's customer support for assistance.
When the waterlevel gets high enough, a small magnet will float in a compartment at the bottom right, of the reservoir and give off the signal to a sensor.
Those floats either leak or corrode over time. What you describe can occur when it is pointing its magnetism in the wrong direction or even when it chooses to raise on its own terms. It is difficult to remove and replace those. Perhaps you can work the clamp loose, remove it and then fool the machine into thinking there is water, with another magnet attached. I have done it. You can see better if the float can be restored, when removed. Mostly it is both cracked open and filled with rust.
No context apart from that is probably a coffee maker.

This sounds like there is an issue with the main circuit board inside the machine. Your best option is to contact a good repairer as this may need a more specialist repair.
Things you might try but turn it off before attempting repair.:
Check the flow meter and sensor: Open the machine and locate the flow meter and the sensor. Unplug the sensor and check the cables for any loose or rusty connections. Clean the connector and plug it back in.
Replace the flow meter and sensor: If the problem persists after checking and cleaning the connections, consider replacing the flow meter and the sensor.
Use manual or program mode: As an alternative, you can use the manual or program mode to control the water volume.
