Washer-dryer is extremely noisy during spin; rumbling, grinding, or roaring sound from drum area.

Safety first: Unplug the appliance. Do not continue to use the machine with severe bearing noise, as it can cause further damage.

Step-by-step checks:

• Check drum play: With the door open, lift the drum up and down. Excessive movement or clunking indicates bearing wear.
• Spin by hand: Rotate the drum manually. Roughness, grinding, or metallic noises confirm bearing issues.
• Inspect pulley: Remove the rear panel and check that the drum pulley bolt is tight and the pulley is not cracked.
• Plan repair: Bearing replacement on Proline washer-dryer combos usually requires tub removal and sometimes splitting a sealed tub. This is a major repair.

When to call a technician: Bearing and spider replacement are complex and time-consuming; professional assessment is recommended to decide if repair is economical.
