Laundry can be calm. Start with balance. Spread items evenly around the drum and avoid one heavy piece that collects water. This keeps spin smooth and lowers vibration.
Choose the right program. A mixed or eco program with sensible spin speed can cut noise without hurting results. Run a higher spin only when you really need faster drying. Check the floor. A level machine works better. Adjust the feet so the cabinet does not rock. A thin anti vibration mat can help in older buildings.
Keep the drum clean. A quick empty cycle once in a while removes residue and keeps the seal fresh. Leave the door open after a wash to let the drum dry. This prevents odor and helps the next spin work as designed.
Use the timer. Set a start time so the machine runs when the home is quiet and power use is lower. If your building has a do not disturb window, plan around it and let the cycle finish before midnight.
With these small steps a FELSEN washer runs with a steady sound and your night stays calm.
