How to Fix / Troubleshooting
Safety first: Turn off power before reaching inside the tub.
- Check spray arms: Spin spray arms by hand to ensure they do not hit tall items. Rearrange dishes to avoid contact.
- Inspect sump: Remove filters and look for broken glass, bones, or other debris in the pump intake. Remove carefully.
- Verify installation: Ensure the dishwasher is firmly secured to the cabinet and not vibrating against adjacent units.
If noise persists and seems to come from the base, the circulation pump or drain pump bearings may be worn and require replacement.
