How to Fix / Troubleshooting
Safety: Unplug before accessing the compressor area.
Steps:
- Inspect mounts: Check the rubber grommets under the compressor. Replace if perished or missing.
- Secure pipework: Gently adjust and secure any pipes that move excessively or hit the cabinet when the compressor starts/stops.
- Normal noises: Some clicking and thumping is normal as pressures equalize. Compare with Neff's noise guidelines in the manual.
