It’s a common wear-and-tear item, especially in hard water areas. Thankfully, for any competent engineer, it's a quick and  simple part to swap out, getting your hot water supply back on track with minimal fuss.

Installation & Maintenance

  • Always disconnect the mains power before starting work.
  • Ensure all connections are secure and  watertight after fitting.
  • Periodically check for limescale build-up around the sensor.
  • Use only genuine parts to maintain boiler warranty.

Frequently Asked Questions
