Possible Causes

Long-term plumbing leak, Poor drainage around spa base, Damaged vapor barrier, Cover left off for extended periods in rain

How to Fix / Troubleshooting

Safety first: Turn off power and avoid using the spa until leaks and moisture issues are resolved.

  • Inspect for leaks: Remove cabinet panels and look for active drips from plumbing, jets, or equipment.
  • Improve drainage: Ensure the spa base is not sitting in standing water and that rainwater drains away from the cabinet.
  • Dry interior: Allow the interior to dry by leaving panels off in dry weather. Use fans if necessary.

Repairing saturated insulation and structural damage may require professional spa service or cabinet repair.
