Loose rubber seal found in drum on LG F1403RD6 washer-dryer

The problem

After a wash cycle on an LG F1403RD6, a rubber seal/gasket about 14 to 15 inches long was found loose inside the drum. The poster did not know where it had come from.

Likely cause

The accepted reply says there is usually a duct at the top of the door seal where steam from the dryer section is blown into the drum, so the rubber piece was most likely from that area. This is a diagnosis only; the exact origin was not independently confirmed in the thread.

What fixed it

Inspect the top area of the door seal/duct connection for a displaced rubber gasket or seal. The discussion does not confirm a specific repair or refitting procedure, so the exact repair was not documented.

Checks to try

• Rubber seal/gasket found inside the drum after the cycle
• Accepted reply identified the usual duct at the top of the door seal for dryer steam entry
