Problem summary

Your Samsung washing machine is making a banging noise that gets worse over time, particularly when the drum is turning. This is a common fault pattern across Samsung freestanding models and almost always points to a mechanical or electrical issue inside the drum assembly or control system.

Banging noises that worsen suggest something is loose, worn, or failing—and continuing to use the machine risks further damage.

Likely causes

Based on 399 similar reports, the most common sources are:

Door seal (27% of cases)
A worn or damaged door seal can allow the drum or tub to move slightly during rotation, causing contact with the outer casing and a banging sound.

Heater element (21% of cases)
The heating element or its mounting bracket can loosen or fail, striking the drum or tub wall as it spins.

Control board (19% of cases)
A fault in the main PCB can cause irregular drum movement or motor control, leading to impact noises.

Other mechanical wear
Motor cushions, drum bearings, or the tub assembly itself may wear or develop play, creating noise that worsens with use.

Why this needs an engineer

The parts involved—door seals, heater elements, control boards, motor mounts, and tub assemblies—are either electrical, sealed-system, or require specialist tools to access safely. Attempting to disassemble the machine yourself risks:

A qualified engineer will diagnose the exact cause and replace the faulty part properly, rather than trial-and-error repairs.

When to call SMC Services

You should arrange a repair as soon as possible. The banging is a warning sign that something is moving or impacting inside—the longer the machine runs, the more likely secondary damage will occur. A fault that starts as a loose seal or bracket can become a cracked tub or damaged motor if left unchecked.

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

Step by step

  1. Stop using the machine. Do not run further wash cycles. Each use risks worsening internal damage and may cause the fault to spread to other components.
  2. Note when the noise occurs. Record which cycle phase produces the noise (wash, rinse, spin) and whether it happens at the start or throughout. This information helps the engineer narrow down the cause.
  3. Check for visible water leaks. Look underneath and around the appliance for water on the floor or inside the plinth. Leaks combined with banging suggest a seal or pipe issue.
  4. Call a qualified engineer. Contact SMC Services or another approved Samsung service provider. The door seal, heater, control board, or motor mounts require specialist diagnosis and safe replacement.

Frequently asked questions

Is it safe to keep using the washing machine while it's making this noise?
No. A banging noise that worsens suggests internal movement or impact. Continuing to use the machine risks damaging seals, pipes, the tub, or motor bearings. Have it checked by an engineer before running another cycle.
Could it be something loose in the drum I can remove myself?
Possibly, but accessing the drum on a Samsung requires removing the outer casing and often the tub assembly—this is not a safe DIY job. If there is a foreign object, an engineer can safely remove it and inspect for damage caused by impact.
What's the difference between a banging noise and a grinding or squeaking noise?
Banging suggests hard impact or loose parts striking something. Grinding or squeaking usually points to bearing wear or motor friction. All three warrant a professional inspection, but the cause and fix differ.
Will the engineer need to replace the whole machine?
Unlikely. Most cases involve replacement of a single component—seal, heater, or control board—rather than a full tub assembly. An engineer will diagnose first and explain the repair needed and cost.
How long does a typical repair take?
Most repairs take 1–2 hours on site, depending on which part has failed and whether it's held in stock. Your engineer will give you a timeline once they've identified the fault.
