Siemens washer dryer delivered in October 2018. Thick black lines on washing when on white wash at 40 degrees or 60 degrees. Engineer report states overloadingor wrong washing detergent. Second Siemens machine with same problem. Won't admit it is a fault with the machine. Is it because it's a washer dryer?

Siemens washer dryer leaving thick black lines on washing
- The problem
- A Siemens washer dryer, delivered in October 2018, was leaving thick black lines on clothes during white washes at 40°C and 60°C. The same issue was reportedly seen on a second Siemens machine.
- Likely cause
- The accepted explanation was contamination around the door seal area, particularly near the dryer heating vent built into the top of the seal. Laundry may be getting caught between the drum and seal, then picking up black marks from gunge or black mould in that area. Washer dryers were said to be more prone to this than washing-only machines.
- What fixed it
- Inspect the top of the door seal where the dryer heating vent enters, and also peel back the seal around the front of the drum to check for gunge or black mould. Use a white cloth to rub around the area to see whether the marks can be reproduced and traced to the seal/vent area. The thread was marked solved, but no confirmed repair outcome was documented.
- Checks to try
- Checked the top of the door seal where the dryer heating vent is built in
- Rubbed a white cloth around the seal/vent area to see if black marks transfer
- Peeled back the door seal at the front of the drum and inspected all around for gunge
- Parts or tools mentioned
- White cloth

Washer dryers tend to be more prone to it because of the way the heating vent for the dryer is built into the top of the door seal. Laundry can get dragged around the door seal if it gets caught in the gap between the seal and the drum. It can pick up marks from the top where the heating vent goes onto the door seal so it can pump hot air into the drum.
Have a a close look up there to see if there is gunge or black mould. Try rubbing a white cloth around there to see if you can pick up any marks to show it’s coming from there. Also peel back the door seal in front of the drum and inspect all around for gunge.
