BA BioDisc Call-Out & Service – Strathaven, South Lanarkshire

BA BioDisc service Strathaven completed for a new customer after a red warning light and F8 loss of rotation alarm appeared on the control panel. The fault was traced to a failed rotation sensor, which was replaced and tested. This call-out also included a full service to restore reliable operation and confirm compliance with SEPA discharge standards.

✅ Fault diagnosis and service tasks

• Rotation sensor: Faulty loss-of-rotation sensor replaced; alarm system tested and confirmed operational.
• Drive belt: Existing belt heavily cracked and slipping. Replaced with new OEM belt and re-tensioned correctly.
• Control panel: Green Darcy Kingspan panel inspected; F8 fault cleared, power and alarm circuits verified.
• Bearings and gearbox: Checked for noise, heat and vibration – all operating within specification.
• Electrical tests: 239 V supply steady; insulation and current draw verified during rotation checks.
• Chamber inspection: Low sludge and crust levels; tank does not require emptying at this time.

After completing these works, the BioDisc was run under observation – rotor alignment, belt tension and alarm reset all confirmed correct. The system now operates quietly and efficiently.

🧰 Electrical repairs and testing

During inspection, the junction box terminals were renewed to maintain safe and reliable electrical continuity. All alarm circuits were tested, including loss-of-rotation and power-failure functions. The plant was left in automatic mode with visual indicators proven.

🛠 Why prompt servicing matters

Ignoring a BioDisc fault such as a loss-of-rotation alarm can quickly lead to treatment failure, odours and costly component wear. Routine inspection and timely belt or sensor replacement prevent total breakdowns and extend system life.
