Atlantic Mechanical Noise / Vibration

Boiler is very noisy, with humming, grinding, or rattling sounds during operation, but continues to run.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn pump bearings, Loose mounting brackets, Fan imbalance, Vibrating pipework

Safety: Turn off power before touching the boiler or pipework.

Check for loose panels: Tighten any loose screws on the boiler casing that may cause rattling.
Support pipework: Secure any vibrating pipes with proper clips or brackets.
Listen to pump and fan: Identify whether the noise comes from the pump (low humming/grinding) or fan (high-pitched whine). This helps the technician diagnose.
Professional replacement: Worn pumps or fans should be replaced by a qualified engineer to prevent failure.
