    Me too - with a bit of a kink

    I moved house and adapted the classixx 7 sensitive drier to draininto the w/m drain outlet, then I stacked it on top of W/M in a narrow cupboard. Thanks to Matt the builder!

    (The "adapting" involved taking the top off and prying a space open through the slotted grill on the back - bye bye warranty)

    1st point - I did not spot the soft black rubber hose at the bottom of the rear of the machine when I did this -
    If I had I would not have found this great post and all the even more grateful readers


    So I got the container full light after one successful load.

    I read the post - did not see the 2 slots on the floor of the condenser channel the first time
    (- really difficult - use a torch )

    Began to fret I had invalidated the warranty by altering the back grill to get the drain hose out
    (which I discovered today I had not needed to do)

    Felt brave today so had another go and read the post really carefully, used a torch, found the slots, had to use to paint stripping shave hooks to pull and lift the flap.

    The sump under the flap was pooled with water but no gunge.
    Cleaned and dried it and ran the drier for 20 minutes but the warning light came on again
    Used a cloth again to dry the sump - no warning light for 15 minutes.

    Point 2. The warning light comes on when sump is full for whatever reason, otherwise it will overflow onto the floor - I tested this by pouring excess water into the sump.

    Now I took the side panel off (left as you look at from the front) - you have to take the electric control and switches panel off to do this - SWITCH OFF THE ELECTRICITY FIRST

    Then I saw how I had kinked the previously mentioned SOFT BLACK RUBBER TUBE,

    So I reconnected the SBRT inside the machine at the top to the container filler
    And disconnected it outside the machine at the bottom
    (and pushed it onto the little grey solid plastic spigot put right beside the drain spigot especially for the purpose)

    I then connected some slightly stiffer transparent plastic tubing to the drain spigot

    - which is what I should have done in the first place !
    - I have switched one of the internal pipe clips on the outside to support this pipe so it does not kink

    Machine running now but I shall leave it on the hall floor draining into a plastic bin for a few loads until I am happy it is clear, or until Matt the builder comes back.

    I really enjoyed this thread - never seen so many grateful readers - and not a single mention of Hitler or any other fascist (obviously until now )

    Many thanks Bnaji, I have just cleaned the 'secret' area and all is well. I did it with a wet sucking vacuum (as I had the fridge freezer go - so luckily was in process of defrosting) if only you had a pound for all us grateful Bosch Drier users!!!!

    A couple of comments:

    The way I lift the access flap in the plastic floor under the (removed) heat-exchanger is to use a very short screwdriver to push one of the clips forward and lever up that side of the flap. I have a long, thin screwdriver ready to push under that end of the flap. I then use the short screwdriver to push the other clip forward, and the flap pops up. The diagram shows the layout.

    I recommend exploring the far reaches of the air passage at the back and to the right (shown by red arrows in the diagram). I have found dry fluff accumulated in the air channels at the very back. I also used a long 'test-tube' brush and found soggy compacted fluff lower down. There seems to be a water collecting sump back there (it is practically at the back right-hand corner of the machine between the motor and the back panel). I sucked more soggy fluff out using a long plastic tube connected to a wet/dry vacuum cleaner. So it looks as though the sump under the access flap beneath the heat exchanger is not the only collecting space for the condensed water.

    With the right-hand side panel partially removed, I could not see any obvious way to open up the plastic parts to gain access. Bosch/Siemens parts diagram does not indicate that the back right parts open up. Bosch/Siemens seem to assume you'll just throw the fluffed-up machine away after six or seven years!

    It is straight-forward, and worthwhile, to remove the rear casing and the metal duct; and clean them. Once unscrewed, the heater will be captive on its wires but can be moved about enough to clean it out. Compressed air would be ideal for blowing the heater elements clear of fluff. I found the temperature sensor was wrapped in a blanket of tight fluff. The safety cut-out has a red button - check it is pressed in before fixing the back casing in place. I had bought a replacement seal, but did not need it. Beware the screws: coarse threads go into plastic; fine threads go into metal.
