Problem summary
Your Samsung WW11 washing machine is making a rattling noise that gets louder with each spin cycle. This is a common fault pattern we see on this model range, and it usually points to wear in one of three areas: the door seal, the drum, or the control board.
Likely causes
Based on 75 similar reports from our engineers, the most frequent culprits are:
Door seal (17.8% of cases) – The rubber seal around the drum door can tear, crack, or come loose over time. When the drum spins, loose or damaged seal material can rattle against the tub or strike the drum edge. This is often accompanied by water leaks around the door.
Drum (17.8% of cases) – The inner drum can develop cracks, or the drum bearing can wear. Debris or a fractured drum surface then hits the outer tub during spin. This noise typically starts gradually and gets worse each wash cycle.
Control board (9.6% of cases) – Electronic faults can occasionally cause mechanical parts to vibrate or move unexpectedly, though this is less common than the above two.
What you can try yourself (DIY)
If you're fairly confident with basic appliance checks, you can inspect for the most obvious issues before calling an engineer. A damaged door seal is sometimes replaceable by a customer without specialist tools.
DIY checklist
Door seal inspection: Open the door fully and look around the rubber seal. Look for visible tears, cracks, or areas where the seal has pulled away from its groove. If it's obviously damaged, a replacement seal kit is often available and can be fitted in 10–15 minutes with just a flathead screwdriver.
Filter and pump: While you're investigating, check the pump filter (usually at the front, bottom of the machine). Trapped coins, stones, or wire can cause rattling during spin. Remove debris and run a test cycle.
Drum rotation: Stop the machine mid-cycle and gently try to rock the drum by hand. Excessive play or grinding sounds suggest bearing wear, which needs engineer attention.
Hose clips and mounts: Make sure all external inlet and outlet hose clips are tight. Loose hoses can rattle against the cabinet.
If the seal is damaged, hoses are secure, and the filter is clean but noise continues, the problem is likely inside the drum or tub assembly, which requires professional removal and replacement.
When to call SMC Services
If drum or tub damage is suspected, or if DIY checks don't resolve the noise, an engineer will need to remove the drum for inspection and replacement. Sealed components and structural parts of the tub are not safe to repair without proper tools and training.
If you're in Northern Ireland, SMC Services can usually book a repair within 2–3 working days.
