Beko DPU8360W condenser dryer.
Water tank full light keeps coming on. I have fully cleaned out the lower reservoir and verified that the pump is working for 30 seconds at 90 second intervals. The problem comes when the drum and heater stop, presumably to reverse direction, then water immediately flows from the condenser evaporator into the reservoir and trips the microswitch so the drum and heater cannot restart. On pressing start the pump immediately empties the reservoir and continues until the next pause. Is there any workaround to get it working continuously again?
A workaround has been in place for a couple of days now and seems to be effective. Time will tell.

I had exactly the same problem and got it fixed by the Bosch repair service today.
The culprit is that in certain areas there may be algae in the air that thrive to grow in the main water reservoir and clog up the water pump that fills the condensation compartment.
(note: There are two water tanks in the Ecologixx 7 - one user serviceable condenser tank up top and the non-user serviceable main water reservoir sealed inside the machine)
This is main water reservoir is located sealed under the water pump under the tumble dryer drum.
Dismantling instructions:
1. remove the top of the tumble dryer first (two screws at the back
2. remove the right side panel with another few screws (looking from the front)
3. disengage the multi-tooth elastic band by twisting the spring loaded roller at the bottom).
After this you have access to the water pump and the Styrofoam float that triggers the empty condenser tank warning.
If the pump is entirely clogged you might need to replace it and the float.
Then clean the bottom water reservoir from the algae infested water with a pump+hose and a bottle washing brush and circulate clean water through the machine (re-engage the elastic band before running the engine) with the Warm-program.
To kill the algae you need to run about 250ml of clear raw vinegar through the pump system by running the machine in the Warm program for 10min and then rinse the excess vinegar out by putting about half a condenser tank of warm water into the machine and running the Warm-programme for 30min. (this will release the clean water into the condenser unit for the self-cleaning function and then pump it back up into the condenser water tank and dilute and circulate the raw vinegar out of the machine).
You should also do a vinegar sanitization run before all extended periods of disuse of the machine by pouring 250ml of vinegar into the large round hole under the top condenser tank (this is where the condensed water is poured for the self-cleaning run).
Run the Warm-program without the condenser tank in place until you can verify visually that the pump is circulating the vinegar through the hose in the top left back corner of the condenser tank opening (there is a overflow drain at the back so everything coming up goes promptly back down into the main reservoir (small hole in the back corner bottom).
Then place the condenser water tank half full with hot water (not boiling) and let the Warm-programme run for 30min to dilute and circulate the vinegar-water solution out of the machine back into the condenser reservoir.
Pat, Have you found a solution to this yet? I have got exactly the same fault today ! Having taken the top & left side of the dryer off, I found what looks like a broken drive belt - not the main drum drivebelt which is fine, but a shorter one (about 18cm diameter loop) with no obvious place for it to have come from. Any clues would be appreciated. Dave ([email protected])
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.
Took advice...isolated from electricity supply...removed left side panel (side with condenser tank), to access the pump. Cleaned it all out (masses of water and grey lint!) and put it all back together again. Bit fiddly getting the panel back on...no screws left over...result!
All working great now.
Simpler solution maybe...There is a 'trap door' that can be removed, which gives access to the area where the water and lint accumulate.
1) Isolate from electricity supply. 2) Take out the condenser unit at the bottom LHS front of the machine (routine maintenance). 3) Underneath of where the condenser unit usually lives..at the back...reach in and open the 'trap door'. This needs a flat head screwdriver and you must release the two plastic clips holding the trap door. 4) You can now access the area where the water and lint accumulate...which makes the 'float' give a false container full fault. 5) Clean out this water and gunk regularly (once a month)!
Hoping this will avoid taking the side panel off again...
