The water tank float magnet won't stay up even when coaxing it with a magnet,take away the magnet and it falls back down even when reservoir is full.so no water sign flashes constantly. new tank ?

Check the water reservoir, if there is a float in the corner. Then that piece is not getting in contact with the reed switch in the machine. Try sliding the reservoir down the back of the machine so that it is always in contact with the back, or if the float is not rising when the reservoir is filled with water then the reed switch cannot detect the magnet in there. You might need a new float assembly.

Hi take out the water tank and place a magnet where the float would sit. If the machine works, then the float is faulty or upside down. If it doesn't work then the sensor behind the magnet is faulty. Replace it. dazza

Inside the water tank there is a magnetic float which is causing the problem. This float is moving always on the top of the water tank as you fill it with water and in reverse as the water level goes down then the float is moving down to bottom also. So as the magnetic float is moving up and down is giving the signal for the water level if it is full or empty.
So possibly now the float is stuck in the bottom and even if you have refill the tank this is still on the bottom of the tank. This can happen from many reasons. First could be that the plastic column that the float is moving is full of scale and it can not move up and down freely any more so you can clean it from scale by decaling it and even clean it with a wire brush.
A second possibility could be that float have a tiny hole and some water enter in the float and this make it to stay on the bottom of the tank. You can visually inspect it and if possible you can dry out the water and weld with a super glue the hole if possible, if it can not be fixed then you need a new float.
If you wand to fix it temporary until you find a new float you can a plastic clip or similar to secure it always on the top however you when the tank is empty it doesn't register so you would really have to keep an eye on the water level to avoid any other problems with the machine.
Good luck

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.

I had the same problem after only a few months. There is a float at the side of the water resivour, this float also has a magnet attached to it and for some reason becomes lodged at the bottom of the tank, telling the machine that there is not enough water in the tank, even when there is. Use a magnet on the outside of the resviour, connect it to the one on the inside and lift very slowly upwards...Hey presto the light stops flashing and the water boils

this has happened to me too just yesterday (26 May 2013), I replaced the tank because I was lucky to have kept the spare bits off the old machine I had and it worked fine. Over time, the water gets into the float and corrodes the magnet. Best to just replace the magnet if you can or the whole tank. Good luck

lot of time you have a magnet in the water tank fill it with water and gently tap the side of machine the magnet is block or jam on empty


THANKS FOR USING FIXYA

The black thing floating in the water tank is a plastic shell with a magnet inside. If you clean it...make sure you reinstall it with the tapered (smaller) side down. There is a slight size difference BUT it will make ALL the difference in the world.

I had no idea there was a magnet in that black/greyish case. The direction of the casing is important.
I had the same problem and that solved it!
