Miele WT 2780 washer/dryer leaving black residue on laundry

The problem

A Miele WT 2780 washer/dryer was leaving black residue on sheets. The residue appeared to be coming from the aperture at the top front of the drum, which was difficult to access. The user had already cleaned the machine as described in the manual, but the problem remained.

Likely cause

The accepted reply said it could be gunk from inside the heating chamber, possibly associated with the dryer air path area near the drum aperture. This was suggested as a probable cause rather than a confirmed fault.

What fixed it

The accepted advice was to check for a cleaning cycle, try cleaning the aperture/heating chamber area with a small dishwasher brush or similar, and try running the washer-dryer cycle a few times. If the contamination was severe, the heating chamber top might need to be removed. The exact repair carried out was not confirmed.

Checks to try

• Residue seen in the aperture at the top front of the drum
• Machine had been thoroughly cleaned following the user manual guidance
• Accepted reply suggested checking whether the machine has a cleaning cycle

Parts or tools mentioned
