Water tank (fill level) sensor issue

[Jacksonhour]

Anyone have experience with this issue? I have a MFR. YR 2009 DeLonghi Magnifica ESAM 4400 model in which my water level sensor appears to be failing. Often when the tank still has plenty of water the display "fill tank" engages which of course will not allow the machine to perform. Currently a little wack, (or 3 or 4) to the side of the tank will usually rectify the issue for a bit. I am in the process of trying to obtain schematics to identify just what I need to replace and hoping such is still obtainable! Just thought I would join this party and see if I might run across some one who may have some insight. Cheers!!

Thanks,
Jacksonhour

Judging by the tank design/sensor it could be magnetic in function. Can't say for sure as I've never used one of those machines. If that's the case it could be the sensor going bad OR maybe the magnet isn't moving back/forth due to scale buildup, etc. Let us know what you find to be the problem.
