Bosch WTL5200SN/04 condense Tumble Dryer

When we use our Bosch WTL5200SN/04 condense Tumble Dryer
(FD 7711 00715) the water goes somewhere else than to the water container at the top (which pulls out for emptying) and the red light indicating that this container is full goes on even when it is totally empty.
I have opened the top of the machine and there is clearly no kink in
the tube leading to this water container. When I blow on this tube from
the top, I hear my exhaled air bubbling through some other space containing water -- the manual mentions some safety container for run-over
water, but doesn´t say anthing else about this. How can I diagnose
this problem?
Thankful for an answer as soon as possible,
Joe

    As I stated in my original description of the problem, I have already opened the cover, examined the water tube visually and seen no kinks and blown through this tube, which indicated clearly that it is not blocked. Any other suggestions?

  • thedep Jul 07, 2008

    Thanks, but the manual does not contain enough information for me to diagnose the problem. How can I be 100% sure that the hose is not blocked? Is there any pump involved that might be broken? Any other ideas?

    Yes, very helpful, thank you!

Hi,

Most Bosch WTL models to my knowledge has a small drain pump at the back of the bottom base underneath a lip top cover. If you would follow the condensation drain hose after the hose connector, the other end would be attached to the said pump. When you force air back and you hear air bubbling, that would be on the pump that has some water still in it.

Rather than kinks or blockage, pls check for any hairline crack or split on the condensation drain hose.

As to "red light indicating that this container is full" pls check if your "water container at the top" "which pulls out for emptying" has some sort of waterlevel detection (a pair of wire attached to a float mechanism. Otherwise, that red light is not indicating that the top container is full but rather that red light is indicating that the bottom base container is full and that the drain pump is not running. There is a float very near the drain pump that activates it. Having said this, then perhaps what the manual is referring to as "safety container for run-over water" is actually the "water container at the top".

Then it would either be the drain pump or the float switch that would have to be attended to.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

You have to open the cover to check it seem the water tube is dissconnected or there is an blockage in the tube.

Water tank full (!) in bosch tumble dryer WTE86301gr


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 a Bosch Maxx condenser tumble dryer that wont work.


Have you taken the condenser itself out from the bottom of the machine? Remove the condenser from the bottom door and rotate the clamp tags which secure it in. Slide condenser out (aluminium mutli-finned box assembly) and carefully take it outside. Use a garden hose with lots of water pressure to spray each vent passage carefully to clear lint and dust away. Passages must be cleared in both directions, long ways and cross ways. Cross ways is the problem area and once you finish clearing the air ways you should see daylight through the condenser easily. Reassemble and always clear lint filter in the door /drum area.
Good luck.

Indesit condenser tumble dryer water light always on even though container empty


Maybe trapped water in the dryer. Switch off and remove power from wall. Remove condenser unit from the dryer (clean the condenser while you have the chance with plenty of water and an old toothbrush - it will probably be filthy). With the condenser unit removed stick an old tea towel in the hole where the condenser was and then tip the dryer on its side. If there is water it will either run onto the tea towel or onto your kitchen floor OR into the water container!

It worked for me, honest...

Bosch tumble dryer


I've sorted mine this morning. First, disconnect from the mains - VERY important! Pull out the metal condenser unit at the bottom, and behind it, there's a small hatch in the bottom to the reservoir. This can get gunked up with water, and is very difficult to clean - HOWEVER - I've found a really easy way of cleaning it. I've got a VAX carpet washer with a hose attachment, and I simply sucked all the water out using that. If you don't own a carpet cleaner maybe borrow one. I did this this morning, and my tumble-dryer's still running happily after an hour! It is possible to clean it out without vacuum, but it takes a LOT longer, and the vacuum of the cleaner pulls out gunk that is hard to access. Another place where gunk collects is behind that hatch right at the back - there's a tube up to the right. I pulled out quite a long chunk of lint. However, that wasn't the solution on it's own, I still had to clean out the reservoir as above.
