How to Fix / Troubleshooting
Safety: Unplug immediately. Do not operate the unit with visible corrosion or moisture near electrical parts.
Steps:
- Dry the unit: Disassemble the housing and allow all parts to dry completely. Use a fan to speed drying; do not use high heat.
- Clean corrosion: Gently clean corroded contacts and PCB areas with isopropyl alcohol and a soft brush. Remove loose oxidation.
- Identify leak source: Inspect the tank, base reservoir, transducer seal, and any hose connections for signs of leakage. Repair or replace the leaking component (e.g., tank, transducer seal).
- Assess damage: If PCB traces are heavily corroded or components are damaged, the main control board may need replacement.
- Prevent future leaks: Handle the tank carefully, avoid overfilling, and ensure seals are in good condition.
