Strong vibration or rattling from spa cabinet when jets are on

Safety first: Turn off power before tightening any hardware.

• 1. Check water level and air:
  • Ensure proper water level and bleed air from pumps.
• 2. Inspect pump mounts:
  • Verify that all pump mounting bolts are tight and that rubber isolation pads are in place.
• 3. Secure cabinet panels:
  • Tighten or reattach any loose side panels.
• 4. Impeller inspection (technician):
  • If vibration persists, have a technician inspect the pump impeller for damage or imbalance.
