Problem summary
A grinding noise during the drying cycle on a Samsung DV90 heat pump tumble dryer usually points to wear in the drum assembly or the components that support it. This is one of the more common faults we see on this model range, and the good news is that the parts involved are replaceable.
Likely causes
Based on repair patterns, grinding noise most often comes from:
Rear drum bearing (around 34% of cases)
The bearing at the back of the drum wears over time, especially with heavy use. When it fails, metal-on-metal friction creates a grinding sound. This is a wear part and will only get worse.
Fan assembly (around 25% of cases)
The airflow fan or its housing can crack or come loose, causing it to catch or rub against the casing during rotation.
Drum itself (around 25% of cases)
The drum surface can develop grooves or damage, or the drum rollers can wear, producing grinding noise as the drum turns.
What you can try yourself
Before calling an engineer, run through these checks:
-
Stop and listen carefully. Remove any items from the drum and run a short cycle. Pinpoint whether the noise happens only when the drum rotates, when the fan runs, or continuously. This helps narrow down the cause.
-
Check for foreign objects. Open the door and inspect inside the drum and seal for coins, wire, or debris wedged between the drum and casing. Remove anything you find.
-
Inspect the exterior. Look at the fan opening (usually at the rear or side) for visible cracks, loose parts, or blockages. Gently move any loose panels to see if the noise changes.
-
Run a test cycle. If nothing is obviously loose or stuck, start an empty drying cycle and listen again. Note if the noise is continuous, intermittent, or linked to a particular phase (heating, tumbling, cooling).
Why this needs an engineer
If the noise persists after these checks, the likely cause is a worn bearing, damaged drum, or internal fan fault. These are sealed assemblies that require partial or full disassembly to replace safely. Attempting to take apart the drum or bearing assembly without proper tools risks further damage and potential safety issues.
In most cases, the repair will involve removing the rear panel, replacing the worn bearing or drum roller kit, and reassembling. Some faults may require a full drum replacement.
