When i start the Bosch WTE84107GB/02 is showing filter.
Having spent two nights trying to resolve the same issue with ours and having searched the internet for help. I would check the following,
Check lower filter and ensure its all clear.
Remove the back of the machine, the pear shaped steel cover part, held on by 10-12 torx/star bolts. Once removed you should see two sensor, one has a red reset button, press the centre and if it clicks you've reset it. Now you could be lucky and just refit the back and it will work o.k but the likelyhood from my experience is that the senors tripped out due to an overheating situation occuring. If it trips out after the reset, remove the cover again, the two sensors are mounted in what is the heater element. I removed this unit but to allow access you need to remove the lower steel duct below the heater element unit, held on my 4 torx/star bolts. Once the ducts removed you can remove the two torx/star bolts that hold the heater unit in position. Once the heater unit is removed, blow out any dust and dirt from the heater coils. With the heater unit removed you can see both the sensors from inside the heater element housing and both mine were caked in dirt so i cleaned the surfaces with a soft cloth and a drop of WD40 (not to much just enough to remove the dirt).
The next part of the machine i'd check is the air intake side. There's a grill area and the right lower side of the dryer to the right of the lower filter housing. Now you can probably remove this grill by resting the machine on it's side and releasing the clips from the underside of the machine but I took off the right hand side panel of the machine, you'll need to remove the top (two screws at the back of the machine slide back and lift off), then you need to remove the control panel, remove the water tank, and then remove the two screws on the left side, on the right side and on the right had side of the control panel, there's one screw, remove this and pully forward gently. You can then access the right side panel forward screws x 2, remove the rear screws, top screws and there one on the underside in the middle. The side panel pulls away backwards away for the front of the machine as it has three locating pegs at the front. Once the panels removed you'll no dout find the area around the motor and drive belt is covered in fluff, just hoover out. with the side panel remove you'll notice the motor unit drives two fans, one you'd have seen when you removed the rear cover and on my machine that was all clear, but the other fan is towards the front of the machine and is covered by a semi circular white plastic cover, which has 4 release clips on the outer egde and one at the rear towards the middle at the motor end and one at the front close to the middle and you won't get you hand into this, you need to release the clip form the underside of base of the machine.Once all clips are removed you can remove the cover, but it's a tight fit but it does come out. Once removed you'll see the fan unit, it's like a hamster wheel and on my machine this was fully choked up with fluff in the middle and in between the fan blades and this is what was stopping air circulation and hence why the machine overheated and cut out. You can hoover out the fan and in the intake system and refit in reverse order, making sure you get the screws back in the right order.
Whilst you have the machine half apart, Once you've refitted the right hand side panel and before you refit the front control panel i'd remove the left hand panel, hoover out. At the bottom left side you'll see the pump unit. There's two pipes going to it, remove the cover retaining screws and remove the cover. Remove both pipes and the two electrical sensors (ones pump and ones the float level senor) Once removed, clean the float sensor and pump you can remove the end cover off the pump and you can also remove the float from the cylinder housing ), remove the filter unit/heat exchanger and clean any sludge etc from inside the pump sump area. Refit
We found that on completion of this the machine was a lot more efficient and made less noise and it's nearly 11 years old so it owes us nothing !!
