We have a Bosch Classixx 1000 Express with black mold on the door sealing ring so bad that neither Cif nor bleach will shift it.Water sits between the inner and outer folds and does not drain thru' the 3 moulded holes. All washes are done at 30 degrees. The machine is only 2 years old and bought from John Lewis.

have you checked the fuse box in your house?

check the pump may have ablockage..,

Hugh It sounds like the rubber door seal is leaking The seal will have tio be replaced if the \re is a hole in it. Quite simple really.

Hi

Try using bleach with hot water, run a cycle with hot water and bleach. Or spray bleach +water mixture on the seal. Run a cleaning cycle with hot water and bleach or vinegar at least once a month to reduce the growth of mold in other parts of the washer. You can also try using 1/2 a cup of Washing Soda or 4 cups of baking soda Crystals and run the machine with no clothes in it. This would remove all the debris, lint & mold growth from the drain pump and drain filter. This would clean the mold from the door seal as well. Hope this helps.. Please post back if you need mor information.

You won't notice the mold on other machines with black door seals because of the color. If your seal is gray, it is a normal thing. Chances are it really isn't mold, but a build up of crud. However in the off chance it is mold, spray the seal liberally with mildew remover, let sit and repeat until the mold is gone. . As for the leaking (assuming the leak is happening at the door), if it is a drip or two during the cycle, although it is not "normal" for this to happen, front loaders do often drip here and there. If you have more problems than a couple of drips, replace the seal. . Other leaks not at the door should be looked at. There aren't too many places it can really leak. It should be easy to find.

RUN A LOAD OF HOT WATER WITH 1 QUART OF WHITE VINEGAR, THAT WILL KILL THE MOLD, THEN WIP IT OFF THE SEAL

The black grime is mold. Once it is set into the rubber it is nearly impossible to remove. Bleach would have been my suggestion but since you've already tried that, replacing the bellows (door seal) is your next option. In the future, when the machine is not in use try keeping the door slightly open for any standing moisture to evaporate.

IMPORTANT: Read thoroughly. DO NOT add detergent or other laundry products to this cycle.
1. Remove all items from the washer.
2. Open the dispenser drawer and 2/3 cup (160 mL) of liquid chlorine bleach to the bleach compartment. DO NOT use more than 2/3 cup (160mL) of bleach per cycle as this will lead to product damage.
3. Close the washer door and dispenser drawer.
4. Select the Clean Washer cycle or a full wash cotton 104 F wash (40 C). DO NOT use any higher temperature as this will cause unnecessary fumes
5. Press Start and allow cycle to complete.
6. If the bad odour persists, repeat the procedure 1 or 2 more times. This may be necessary if this is the first time you have run this cycle.
7. After the cycle is complete, leave the door open slightly to allow ventilation and drying of the washer interior.
8. Repeat the cleaning procedure monthly.
To maintain the washer freshness:
1. Use only HE High Efficiency detergent.
2. Leave the door open after each cycle to for better ventilation and drying of the washer interior.
3. Use warm / hot water in your machine unless the fabric you are washing requires cold.
4. Use the correct amount of fabric softener.
5. If your laundry room is damp, use a dehumidifier.
6. Clean the door seal of visible residue.
