Washer-dryer is extremely noisy during spin, with a rumbling or grinding sound from the rear of the drum.

Safety first: Unplug the appliance. Spinning with failed bearings can cause catastrophic damage.

Step-by-step checks:

• 1. Spin by hand: Rotate the empty drum by hand. A rough, grating feel or loud rumble indicates bearing wear.
• 2. Check for play: Lift the drum up and down at the front. Excessive movement relative to the outer tub suggests bearing or spider failure.
• 3. Inspect for leaks: Look for rust streaks or water marks at the rear of the tub and under the machine, indicating a failed bearing seal.
• 4. Plan repair: Bearing replacement on Montpellier washer-dryers usually requires full tub removal and splitting. This is a complex job often best left to a professional. In some models the rear half of the tub with bearings is replaced as a complete assembly.
