My dryer keeps saying the water reservoir is full, even though it is empty. If I restart the cycle it will work for a couple of minutes and stop again. What is the sensor that is sending this message? And where is it located? TIA
Is this a good question?

Don't know that particular model but here's some information that may help.
It is for a Bosch WTW84270/0 (Ecologixx 7) tumble dryer.
Looking through the parts diagrams there are only two sensors or I think that there are two.
A Sensor NTC Item ID # 0527, part # 00170961 (supplier example only) but this seems to be a temperature sensor given the specifications and an Electrode, Moisture or Humidity sensor Item ID # 0217 part # 11018215 This supplier calls it a moisture sensor, this supplier calls it a humidity sensor and Bosch calls it an electrode.
I wonder if there's a switch closely associated with the tank but given the above examples which have different names for the same part/part number, it may not be called a sensor or even a switch.
Looking at a zoomed in image of the tank (click on image in the tank link above to zoom in) there's one image showing a lever on the side of the tank. Perhaps this latches into something in the machine to open it or to indicate that it is full, I don't know. Maybe it is stuck. Something to check perhaps. Bosch calls it a container condensed water and not a tank although the other suppliers listed above do call it a tank. Go figure (Item ID 0516 part # 00707089)

Hi. Thanks for your help. The diagrams helped a lot, I took a look at the dryer and as far as I can tell, maybe the problem is the sensor (the two-pronged thing) on the lower water tank, attached to the pump assembly : https://www.bosch-home.co.uk/store/00146...
I found nothing else that may be the origin of the problem, but... who knows...
Doesn't look like it's a separate part but integral to the pump.
Maybe test it with an Ohmmeter to see if it changes either like a switch i.e. open and close or like a thermistor i.e. resistance value changes with water level.
I´ll do that. Thanks, I will keep you posted. All the best
Hello, have you fixed the issue? Was it the pump or something else? Kind regards

I've had the issue where it is constantly saying the tank is full on the Bosch Serie 6 self cleaning condenser dryer. There is a compartment at the back of the dryer where the pump is. You can pop out the pump and there is a sensor beside it with 2 metal strips that detect the water level. Gunk gets caught between the 2 metal strips, clean that away and it solves that problem.

Hi Michael, any pointers on how to access/open that department?
See my comment and pictures above.

I just found the compartment and it fixed my Bosch Serie 6. See attached pictures.
There are two snap locks at the top where the screwdriver is pointing on first picture.
