Grinding or rattling from a Samsung WF50BG8300 has a short list of causes in the manual: metal objects such as coins in the drum or filter case, overalls and metal-decorated clothes, a washer that is not level or has its shipping bolts, and the motor noise that is normal in operation. If a clunk survives all of that, Samsung's Repair Guide points a technician at foreign matter between the motor rotor and stator and at the wiring; the Digital Inverter motor is covered for 10 years, part only.
Differential
Likely causes of “Samsung front-load or top-load washer makes grinding, squealing”, and how to tell them apart
- 1
Coins, buttons or metal pieces in the drum or the filter case
What separates it A sharp rattle that changes with the spin and comes from low in the drum or near the filter
How to confirm Empty the pockets and look in the drain filter; Samsung says metal objects can make noise and should be removed from the drum or filter case
- 2
Overalls or metal-decorated clothes
What separates it A clanking that matches the load and disappears with other laundry
How to confirm Wash such items in a laundry net or turn them inside out; the manual says this noise is normal
- 3
A washer that is not level or has shipping bolts still fitted
What separates it Thumping during the spin and a rocking cabinet that walks on the floor
How to confirm Check the shipping bolts and press down on each corner of the top
- 4
A foreign object or fault at the motor
What separates it A grinding or scraping that continues with an empty drum
How to confirm The Repair Guide's check is for an alien substance between the rotor and the stator; this is technician work
Before you touch a setting
Record this first — changing settings destroys the evidence
- When the noise happens: fill, wash, drain, spin or all the time
- What the noise sounds like: a metal rattle, a scrape, a hum or a thump
- Whether it continues with an empty drum and whether the washer is level with the bolts removed
Try in this order
0 of 5 completedEmpty pockets and check the filter
ReversibleTurn the washer off and unplug it. Open the filter cover at the lower front, drain the water and look in the drain filter and the filter case for coins and small objects.
Check the load type
ReversibleOveralls and clothes with metal decorations can make noise; use a laundry net or wash them inside out.
Check level and the shipping bolts
ReversiblePress each corner of the washer top, adjust the leveling feet, remove any shipping bolts and move the washer so it does not touch anything.
Run an empty Rinse+Spin
ReversibleIf the noise disappears with an empty drum, it was the load or an object; if it remains, it is mechanical.
Stop if it grinds empty
ReversibleSamsung's Repair Guide covers checking for foreign matter between the rotor and stator and the motor wiring (15 ohms between each pair of motor wires), which is a technician's job.

Exact questions
Common questions
Why is my Samsung WF50BG8300 making a grinding noise?+
Coins or metal in the drum or filter case, metal-decorated clothes, poor leveling or an object near the motor.
Is motor noise normal?+
Yes. Samsung says the motor can cause noise during normal operation.
Where do coins end up?+
In the drain filter case and the drum; the manual says to remove them after washing.
What is a Digital Inverter motor?+
The washer's drive motor. Samsung's U.S. warranty covers the motor part for 10 years.
Can I test the motor myself?+
The Repair Guide gives a technician's value of 15 ohms between each pair of motor wires; Samsung tells consumers not to service the washer themselves.
Do unlevel floors make noise?+
Yes. Check level and shipping bolts as the manual's vibration checklist says.
Do pillows make noise?+
Samsung says to remove the filling of pillows and cushions and wash only the covers.
What sounds are normal at the start?+
Before the washer starts to fill it makes a series of clicking noises to check the door lock and does a quick drain.
Can the drain pump impeller make noise?+
A blocked impeller can; the manual says to make sure the impeller inside the drain pump is free of debris while the drain filter is removed.
What are the Repair Guide's motor checks?+
Check whether there is any alien substance between the rotor and the stator, and check the motor power wires (blue, white, red) at 15 ohms between each pair.
What does the rotor warning say?+
Removing the rotor requires a lot of force because of its magnetic force, so it is a technician's job, not an owner's.
Which sounds are just laundry?+
Overalls and clothes with metal decorations make noise while being washed, which Samsung calls normal.
Where is the drain filter case?+
Behind the small filter cover at the lower front; coins and small objects that reach it can rattle, and the manual says to remove them after washing.
Is this noise covered by the warranty?+
Parts and labor are covered for 1 year, the stainless tub for 3 years and the Digital Inverter motor for 10 years, part only.
What should I do before calling service?+
Empty the pockets, check the filter case, check the shipping bolts and level, and run an empty Rinse+Spin to see whether the noise is the load.
