I suspect the bearing on our Bosch WTA4007GB/02 may need replacing, the dryer makes a squeaking noise for a couple of minutes when first switched on. The noise then stops for the rest of the drying session. I’ve taken the top and rear panels off and can see where the bearing is mounted but cannot work out how to get fully into it. I think that further dismantling may be required?
Does anyone know how to do this, or even better can a service manual be downloaded anywhere?
Many thanks for any advice offered.
