Gledhill unit emits a burning smell or shows signs of scorching near electrical components

Safety: Immediately isolate power at the consumer unit. Do not continue to operate the appliance until the source of overheating is identified and repaired.

Steps:

• Visual inspection: After cooling, remove covers and inspect immersion terminals, pump connections, and the PCB for discoloration, melted insulation, or charring.
• Tighten/replace terminals: Loose screws at high‑current terminals can cause arcing and heat. Tighten or replace damaged terminals and cables.
• Replace burnt components: Any relay, connector, or PCB section showing heat damage must be replaced. Do not attempt to reuse burnt parts.
• Check load ratings: Ensure all replacement components match or exceed the original current and temperature ratings specified by Gledhill.

Note: If the smell persists after visible faults are corrected, have the unit inspected by a professional before returning it to service.
