Samsung WF42H5400AW/A2 Washer Shaking, Vibrating, or Making Unusual Noise: Checks and Parts

Direct answer: A Samsung WF42H5400AW/A2 Washer that shakes, vibrates, moves across the floor, or makes banging, thumping, rattling, grinding, or clanging sounds can have a simple load or leveling problem, but the symptom may also involve internal components. Check the load and washer stability first. If the washer still vibrates or makes unusual noise when the drum is empty or the load is balanced, inspect the installation and consider whether the rear shock damper / shock absorber or bearing components are involved.

Do not assume that one sound identifies one failed part. Several conditions can create similar symptoms, and more than one component can contribute to excessive movement or noise. Before ordering, confirm the model label reads Samsung WF42H5400AW/A2 and compare the part number on the existing component, if accessible, with the replacement part number.

What should you check first on a Samsung WF42H5400AW/A2 Washer?

Begin with safe, external checks. Stop the cycle, unplug the washer before examining or moving it, and keep hands clear of moving parts. If the washer is full of water, follow the appliance’s normal drain procedure rather than attempting to force the door open.

• Check the load: A small, tightly bundled, or uneven load can make the washer shake during high-speed spin. Pause safely and redistribute the clothing. Avoid combining one heavy item with several very light items.
• Check the floor: The washer should stand on a firm, stable surface. A flexible or uneven floor can amplify vibration even when the washer appears level.
• Check the feet: Confirm all four feet are firmly contacting the floor and that the cabinet does not rock when gently tested. Recheck stability after any adjustment.
• Consider recent movement: If the problem began after installation, relocation, or leveling, review the installation condition and any applicable shipping or transit hardware according to the appliance documentation.
• Check for objects: Look for coins, fasteners, or other foreign objects in accessible areas such as the drum, door seal, or drain filter area, using the owner’s instructions for access.

Record when the symptom occurs. Does it happen only during high-speed spin, with clothing inside, or even when the drum is empty? A short audio or video recording can also help distinguish a rhythmic sound from a one-time rattle or a noise associated with drum rotation.

Why can the washer vibrate even when all four feet touch the floor?

Contact with the floor does not always mean the washer is stable. One foot may have limited pressure, the floor may flex, or the cabinet may still rock. A load can also become unbalanced only at higher spin speeds. Test the machine’s stability with power disconnected and avoid placing hands near moving parts.

If the Samsung WF42H5400AW/A2 Washer shakes when empty, repeatedly walks after the load is redistributed, or produces a persistent thump or knock, the issue may require inspection beyond basic leveling. A worn or damaged suspension component can allow more tub movement. Noise that follows drum rotation may also point toward bearing-related components, although the sound alone cannot confirm a diagnosis.

Could the rear shock damper cause shaking or unusual noise?

The verified replacement part for this model is the DC66-00470B Rear shock damper / shock absorber. A shock damper helps control tub movement during operation. If inspection indicates that this component is worn, damaged, loose, or otherwise unsuitable, it may be a candidate for replacement.

Compare the part number carefully before purchase. The verified fitment for the Samsung WF42H5400AW/A2 hub is DC66-00470B. Do not replace it solely because the washer made one loud sound or shook with one unbalanced load. Confirm that the model label and part number match, and use an appropriately qualified technician if access or repair procedures are beyond your experience.

Could bearing components be related to grinding or drum noise?

Some customers describe bearing-related symptoms as grinding, rumbling, clanging, or a noise that changes as the drum rotates. However, an audio description cannot establish which component has failed. The verified bearing products for the Samsung WF42H5400AW/A2 Washer are:

• 6601-000148 — Bearing Ball
• 6601-002637 — Bearing Ball

These are separate part numbers, so confirm which number applies to your repair before ordering. Do not substitute one bearing ball for the other without verifying the model label, the existing part, and the required part number. If the drum has abnormal play, the noise is persistent with an empty drum, or access requires substantial disassembly, consider professional diagnosis.

Which verified parts fit the Samsung WF42H5400AW/A2 Washer?

For the verified Samsung WF42H5400AW/A2 Washer noise-or-vibration issue, XPart Supply’s exact model hub is the Samsung WF42H5400AW/A2 Washer parts hub. It currently identifies these verified replacement products:

• DC66-00470B — Rear shock damper / shock absorber
• 6601-000148 — Bearing Ball
• 6601-002637 — Bearing Ball

Use the hub to keep the model and symptom together, then open the individual product page for the part number you have verified. Product fitment data supports this exact model, but you should still confirm the rating plate or model label and compare the part number before ordering. A matching model does not remove the need to identify the failed component correctly.

When should you stop using the washer?

Stop the washer and disconnect power if it moves aggressively, produces a severe grinding or metal-on-metal sound, has a damaged cord or plug, leaks, smells overheated, or shows visible damage. Do not continue testing a machine that could damage the floor, cabinet, drum, or surrounding property. Arrange qualified service when the required inspection involves internal access, heavy lifting, electrical testing, or unfamiliar disassembly.

Samsung WF42H5400AW/A2 Washer noise FAQ

Why does the Samsung WF42H5400AW/A2 Washer shake only during spin?

High-speed spin can expose an uneven load, unstable feet, a flexible floor, or an internal suspension concern. Test with a properly distributed load and check stability before assuming a part has failed.

Why does it vibrate when the drum is empty?

Empty-drum vibration or persistent noise deserves closer inspection. Check installation and accessible foreign objects, then consider professional diagnosis of internal components.

Is DC66-00470B guaranteed to fix the shaking?

No. DC66-00470B is the verified rear shock damper / shock absorber for this model, but multiple causes can produce similar symptoms. Confirm the diagnosis and part number first.

Which bearing ball should I order?

The verified options are 6601-000148 and 6601-002637. Confirm the appliance model, inspect the existing part if possible, and verify the required part number before selecting one.

What information helps diagnose unusual noise?

Note whether the sound is banging, thumping, rattling, grinding, or clanging; whether it follows drum rotation; whether it occurs with an empty drum; and whether the issue began after moving or installing the washer. A short recording may also help.
