"Fill tank" - Coffee machine indicates that water tank is empty and does not turn on. This error may be caused by a broken water level sensor 5232104600. This water level sensor should be replaced.
Before doing this: I had different model but same issue. Make sure the black 'rectangle' piece inside the tank (in mine it's in the middle, at the bottom), can move up and down freely on its 'rails'. I nudged it first, then noticed a bubble of air above it, so I slightly tilted the filled tank a bit. The air bubble came out and the black 'rectangle' floated back up to the top, with the machine recognising a full tank again.
Hi I have a DeLonghi Prima Donna ESAM 6900 with a similar issue. It’s not picking up the magnet in the float of the water canister. However, when I touch and pull a magnetized screw driver to the sensor it senses it and the “fill water” message goes away. Should I replace the sensor? Thanks for posting your video. Very helpful.
Buy a new water reservoir for $28 and it comes with a fresh magnet which increases the connection between the sensor and the float. They wear out over time. Wire fix didn’t work for me.
Thank you for this suggestion as it fixed my problem of the Delonghi Rialto not sensing the water reservoir ("Fill tank" message) unless the reservoir was pushed quickly with force.
I have Magnifica S, also showed fill water tank. The float in the tank was working fine. Opened the machine, removed the magnetic switch - still water tank empty light stayed on, connected switch pins (where the switch plugs in) - also no change. So I have no idea what the problem was and sent to repair shop.
I thought it was a mechanical not electronic sensor, because if I slam in the water container stronger, it almost always fixes the problem. Sometimes I have to do few times.
Hi. 1. Fist of all check water tank. Inside water tank there is a small reservoir with the small black buoy. It should be near sensor when water tank is in his place. That black buoy should move easily and when you fill water tank it goes up, but when you use water - it goes down step by step. When water level becomes low it gets into the zone of sensor and sensor indicates the low level of water. 2. Check if the sensor is in the right position; 3. Test the resistance of the sensor. If it is 0 - sensor is bad; 4. Try to disconnect sensor and to turn on the machine. I tested this on ECAM23.450 and the machine didn't see the problem. it worked without sensor but of course I was not informed about water level.
The water chamber float has a magnet in it that trips the sensor; I found that adding one of those small neodymium magnets to the float solved the problem without replacing the sensor.
Hi, I have the opposite issue, the machine can run empty on water without sensing it. I've checked the water tank and the float is moving. Is it possible that the same sensor produces the issue?
It's a sensor in water tank failure or machine sensor. Just have it in my own machine. 1. Might be stuck sensor on the machine (just like on the video) - small chance 2. Stuck float in water tank - medium chance 3. Float in water tank is moving but the magnet is not strong enough (it demagnetised during all those years) - replace water tank - medium chance
@@MC-zu5lj thanks for the reply. Spoilers: it was the water tank magnet. After I got a new tank it worked. Of course I changed the sensor first because why a magnet would go wrong? :)
