Hi Jim, thanks for getting that infomation for me..

Just to confirm, your appliance is a WTW863S1GB/14 built in Sept of 2013

I want you to try something for me if you will..
  • Remove the tank from its holder.
  • Take off the left hand hose from the rear of the tank at the back of the machine and hold it over a bucket..
  • Get a cup or two of water and pour them into the tank holder..
  • Wait until it drains away, then turn the appliance on and see if any water gets pumped up the hose into the bucket
Customer: replied 2 years ago.

I cannot locate the pipe at the outside back of the machine, please can you be more detailed in the precise location of the hose.

You ask me to pour 1/2 cups of water into the tank holder; is this the container for the condensate?

The part number on my dryer does not show "/14"

the machine was certainly purchased in Nov. 2013.

Expert:  George-Allsorts replied 2 years ago.
Ok Jim, we will do this a different way...

  1. Take out the condensate container
  2. Pour a cup or two of water into the housing that the condensate container was inserted in to..
  3. Wait until it drains away, then turn the appliance on.
  4. Have a look into the housing which you poured the water into and see if there is any water flowing downward into the area where the hole in the condensate container would be
Customer: replied 2 years ago.

Your last suggested procedure completed and yes

water flowed from top of compartment above where the entry to the condensate container would be

located. Bingo we are making progress.

Expert:  George-Allsorts replied 2 years ago.
Ok Jim, this would indicate that all is well with the pump and circulatory system of the appliance..

Is the appliance heating well enough?
Customer: replied 2 years ago.

Yes there appears to be a fair amount of heat being

generated, the outside cabinet feels quite warm and the garments are being dried but more slowly than normal. Our worry is:- where is all the water going

which was formerly collected in the condensate tank?

.

Expert:  George-Allsorts replied 2 years ago.
Can you turn off the electricity to the appliance, open up the condenser cover, and remove the condenser please...

Once this is done, can you get a towel to lay on, place it in-front of the appliance, lay on it, and reach into the condenser compartment to the rear... At the rear you will find a dip. Reach into the dip to see if there is a build-up of fluff or other debris in the dip.. If so remove it.
Expert:  George-Allsorts replied 2 years ago.
Jim, I will be away for about an hour and will follow-up when I return

George
Customer: replied 2 years ago.

I understand your instructions but I am not sure how to

remove the condenser cover. There does not appear to be any external fasteners.

Does the panel just pull out? It appears to require a

lot of force to remove it from the cabinet. And you-know-who would give me a load of earache if I bent

or broke something!!!!!!!!!!!!!

Customer: replied 2 years ago.

George, I am now obliged to leave the computer until

tomorrow hope to be able to contact you in the near future.

Regards Jim.

Customer: replied 2 years ago.

PS

Have now made arrangements to return to computer

at hourly intervals throughout this evening.

Regards Jim.

Expert:  George-Allsorts replied 2 years ago.

Sorry Jim, I've just rechecked and fount that you can't clean the condenser on yours as the base unit is a complete unit with a heat pump system.

In answer to your other question about where the water goes; what water does not go into the condensate drawer is reused internally in the self cleaning system..

If the dryer takes too long to dry the clothes, but is otherwise working correctly; try cleaning the sensors just behind the filter inside the door...

My works number is #07787182156 if you need to chat but can't otherwise get me

Thanks George for all your deliberation and patience

in dealing with an octogenarian. I do understand your finding with respect to inaccessibility.

This appears to be yet another example of our throw away society.

Thanks again, Jim.

Expert:  George-Allsorts replied 2 years ago.
Wow Jim, I had no idea.. I hope i live long enough to be one..

I will await the results of your testing tomorrow after cleaning the sensors..

If I don't hear from you during the weekend I will chat with you after the Bank Holiday.. Have a good one.

OK Thanks George.

Take your time; I'll be around if you need me.
Customer: replied 2 years ago.

Hi George don't laugh or swear; since our last communication we have carried out an exhausted search of our archives and located the paperwork with respect to the purchase of the Bosch Dryer AND

would you believe the Dryer is still under warranty.

A Bosch engineer is visiting today.

Apologies for all the unnecessary deliberations

Regards Jim.

Expert:  George-Allsorts replied 2 years ago.
Well, that is actually good news.. Let me know how it goes.. It would be interesting to know what was causing the issue
Customer: replied 2 years ago.

The Bosch engineer came with all the diagnostic test gear and said the machine was in working order and was unable to find any malfunction.

The jury is now out until the next big wash session.

Expert:  George-Allsorts replied 2 years ago.
Ok Jim, thanks for letting me know... I'm going to close this question down, but, you have my number to ring me if you need to..

George
