As a matter of fact I have solved the problem. The dryer is now fully functioning again. :-)
I'll try to explain how to fix the problem:
The water that condenses in the condensor (doh!) drips down into a container situated below the condensor. The moist air that passes through the condensor is the same air that circulates via the clothes, thus it also contains some lint that the filter doesn't catch. Over time there will be some build-up of lint and mucus (?), clogging the tank AND a sensor that sends a signal to the electronics to start the pump that evacuates the condensed water to the removable tank in the upper part of the machine. This messes up the function of the water evacuation system.
Alright, pull out the condensor and find a hatch in the 'floor' in the farther part of the compartment. Below the hatch you'll find the container that collects the condensed water. Start by cleaning it as thoroughly as you can. There are a few 'nooks and crannies', take your time, also flush with some fresh water and maybe some gentle cleanser to get rid of the mucus. The pump and the sensor for the pump are located in the left part (viewing from front of the machine) of the container. Try to flush there as well.
If this procedure doesn't solve the problem you'll have to disassemble the machine to also be able to remove the pump and sensor housing. I had to do this on mine. Quite a few screws to remove and keep track of, but pretty straight forward if aren't too uncomfortable with 'fixing things'.
I have some pictures of the 'project' somewhere, let me know if you would like to see them or if I may help you some other way.

I have had the same problem with my Bosch Tumble Dryer and fixed it by following the above advice. I don't know if mine was particularly bad, but I also had to remove the side-panel to gain access to the pump and sensor mechanism (which isn't difficult) and I doubt that it would have been possible to have cleaned it sufficiently by accessing through the 'hatch' in the floor of the condenser compartment, so I would recommend the removal of the side-panel for a more through clean. I wasn't quite sure what BR/Hans meant by 'mucus' - but I do now! It's amazing how much 'sludge' was in the bottom of the lower collector tank - and not really surprising that it was continually cutting out! I would recommend doing this procedure regularly as I'm sure the dryer will operate much more efficiently now I've removed not only the copious amounts of sludge in the tank and around the pump/sensor, but also all the other fluff and dust which the removal of the side panel gives access to.
Hi Leslie, good to hear that I could help you! And yes, its amazing how much sludge that builds up inside these machines!
The problem is a coating of slime on the tank in the bottom of the machine. This causes the machine to think the tank is always full so cuts the machine out with the icon telling you to empty the condensate container. For a fix, you have to fully remove the slime or it will just build up again.
The best way to do this is to fill the condensate tank with water and pour it into a measuring jug and see how much it holds. Next boil a kettle of water and fully dissolve a dishwasher tablet in a jug or container with the same amount of water that the tank holds. Next, pour the water (use a funnel or pipe) into the compartment where the condensate tank slides into, it should run down into the tank at the bottom of the machine. Leave it for an hour, then put the condensate container into it's slot on the machine and start the machine. The water should pump up into the container, probably with a load of fluff. Hopefully the machine will now work properly.
I don't have a solution to this but I do have exactly the same problem. Did you manage to fix it? Help would be apreciated.

Hi there!
I also have a Bosch tumble dryer that signals "Water tank full" when it in fact isn't. I Googled and found your post regarding having the same problem. Have you got your dryer fixed? If so, please let med know the solution. :o)

Hi, have you got your dryer fixed? I have exactly the same problem. Best regards, Jiri
