Likely causes (Samsung freestanding washing machine):

Problem summary

Your Samsung WW90 is making noise during the wash cycle or spin phase. This could be a rumble, grinding sound, or excessive vibration. Noise can occur during any stage of the cycle and may be accompanied by visible shaking of the machine.

Likely causes

Noise in models in the WW90 range typically points to one of three problem areas:

Control board (PCB): The printed circuit board controls the motor and drum speed. A faulty PCB may cause the motor to run erratically, creating grinding or humming noises.

Door seal: Wear or damage to the rubber door seal can allow items (lint, coins, or small objects) to fall between the drum and the tub wall. As the drum spins, these objects rattle or bang against the metal surfaces.

Pump: The drain pump can become clogged or develop internal damage. A failing pump often produces a grinding noise during or after the spin cycle.

Why this needs an engineer

All three likely causes involve either electrical components, sealed systems, or internal mechanical parts. The PCB requires safe electrical diagnosis and replacement. The door seal sits within the machine's sealed tub assembly. The pump is part of the sealed drainage system.

Attempting to disassemble the machine yourself risks: - Exposure to mains voltage if the PCB is involved - Damaging the tub or seal if you open the machine - Water damage if the pump housing is disturbed

A qualified engineer will run diagnostic tests to identify which component is failing, then replace or repair it safely.

Warning signs that need immediate attention

If you notice any of these, stop using the machine and contact an engineer.

When to call SMC Services

If your WW90 has been noisy more than once, or if the noise is new and persistent, a professional diagnosis is the most reliable next step. An engineer can establish whether the issue is the PCB, door seal, pump, or something else, and arrange the appropriate repair.

If you're in Northern Ireland, SMC Services can usually book a repair within 2-3 working days.

Step by step

  1. Check for external obstructions. Make sure the machine is not pushed against a wall or cupboard and that nothing is resting on top of it. Move it slightly away from surrounding surfaces and run a short wash cycle to see if vibration reduces.
  2. Note when the noise occurs. Is it during wash, rinse, or spin? Does it happen every cycle or intermittently? Pass this information to the engineer—it helps narrow down the cause.
  3. Do not attempt to open the machine. Resist the temptation to remove the front panel or drum. This involves mains voltage (if the PCB is faulty) and damage to seals. Stop here and call an engineer.

Frequently asked questions

Can I open the drum myself to check for stuck objects?
No. Opening the drum risks damaging the seal and flooding the machine. If an object is trapped between the drum and tub, an engineer has the correct tools to remove it safely.
Will the noise damage the machine further if I keep using it?
Possibly. If the door seal is damaged or the pump is failing, continued use can worsen the fault and lead to water leaks or motor damage.
Is noise always a sign of a major fault?
Not always, but in the WW90 range, noise that recurs or worsens usually indicates a component issue that needs professional attention. A one-off noise is less likely to be a problem, but persistent noise warrants a check.
Could it just be unbalanced loading?
Unbalanced load can cause vibration, but load-related noise is usually temporary and stops after the machine rebalances itself. If the noise is happening every cycle regardless of how you load it, the cause is likely mechanical or electrical.
How long do repairs typically take?
Most noise-related repairs take 1–2 hours on site. Parts replacement may add a small amount of time depending on availability.
