SOURCE: The Sensor Magnet for water tank does not float to the top

OK, first of all, I do not recommend my solution if you are forgetful or do not check your water level manually daily.

However, I found a super easy solution.

The way the unit works is to use a float in the water chamber with a magnet on the bottom. When their is enough water in the tank, the float rises and the magnet on the bottom floats to the top of the magnet chamber. When it floats up, it aligns with a sensor in the machine that allows the machine to operate. When the the water level lowers, so does the magnet and drops below the internal sensor disabling the machine with a "Fill Water Tank" error message.

To eliminate this error and allow the machine to operate, I simply popped off the lid to the magnet chamber with a butter knife and turned the water chamber up side down to let the magnet float fall out. Remember to empty the water first.

Here comes the highly technical part. Turn the magnet float upside down and slide it back into the float chamber. Since the actual magnet is on the bottom of the float it now is at the top allowing the internal sensor to turn off. No more error message!

The reason I do recommend this is because this completely defeats the purpose of the sensor and will most likely damage your machine if you run it without water. Keep you tank filled however and you will eliminate the frustration of a "float gone bad" keeping you from your morning caffeine.

SOURCE: leaking coffee grounds and water

HI
There should be a small amount of coffee residue and about an oz. of water going into the drip tray. This is the pressure relief process, when the machine finishes the coffee making. If it didn't release the pressure thhis way you could have an explosion of coffee when it cycles back.

This sounds more like the inlet valve is being supplied with constant power when its not supposed to be.This is normally due to the old valve spikeing the PCB & now you are getting constant power supply to the new valve.I think PCB needs to be changed as well.OE error was an after effect of the machine over filling.

SOURCE: The magnetic valve is not working /the water does not shut off

go to the makers web site bosch this is a very common fault and this valve is out there at about 7 dollers/6pounds i buy them every day.adrian,,,,,
