Thanks for all the advice and the pictures. Just saved at least $200 - $300.
My Bosch dryer (
WTW86560AU) had the same issue where it stopped with beep sound that the condensed water in the container need to be emptied. The water was empty and I had cleaned all the filters multiple time. After reading so many posts I got the confidence to dismantle the dryer
I was not that lucky as many others here as I had to remove the entire dryer including the drop to do the cleaning as the cleaning compartment was just below the steel drum.
I am adding below the steps I followed so that if somebody else have issue with the similar model it would be easy.
Total time spent: 3.5 hours.
1) First remove the front door, remove both the side panel followed by the back outer panel (The inner panel can be removed later).
2) Tilt the dryer so that it rests on the front panel (As the door is already removed the dryer can rest nicely. I placed a bed sheet, plastic to avoid getting scratches especially considering that the new one cost $1850/-
)
3) The spring connected from the bottom of the dryer to the motor part needs to be removed. I used a plier and removed the spring(the one connecting the motor. First tried the end that connects to the bottom of the dryer but couldn't do it)
4) Remove the belt.
5) Remove the screws from the back of the dryer inner panel which connects the steel drum to the panel. After the screws are removed you can see a small lock kind of thing which can be easily removed using a screw driver.
6) The plan is to clean the area where the water is pumped up from the bottom of the dryer. So follow the black tube, which connects to, the top left water container. The water is supposed to drip from this tube to the container. The other end of the tube is what needs to be cleaned.
7) Identify the above location and remove the screws. You can see that there are two parts once removed. One is kind of a small transformer and the other one has two small steel pieces(may be it is some sort of sensor).
8) The steel piece and the small container need to be filled. I used wipes to clean both.
9) Now the most difficult part which is to put everything back together. You need to follow the steps in opposite order. I am not sure whether the steps I followed to fit the drum, belt, spring and the inner back panel is right. May be somebody can confirm. I fitted the drum, belt, then spring and then the back inner panel. When the drum was screwed to the back panel I could feel the tension due to the belt. I just pulled the drum and tightened the screws.
10) Most of the time was spend in fitting everything back.
11) Remember to fit the different tubes properly and try to rotate the drum and make sure it does not touch the drum. It was a little tricky to fix the control panel and the condense water tray back in. Anyway I managed to do it.
12) It is a week since I did all this and I have 4 cycles of cupboard dry till now and the dryer is all working as new
. Very happy with my decision to dismantle the dryer myself.
13) I know that I might need to do this again after 4 years. Bosch should have at least kept this compartment easily accessible which would have made all this much easier. Bosch makes great machine but the decision to have this compartment below the drum needs to be looked at.
14) I have taken a lot of photos during the process. Attaching some of them here.
