The Worcester Bosch 87161461640 Flow Sensor is a genuine replacement component that monitors the flow of water within your boiler’s primary circuit. By detecting movement and speed of water through the system, the flow sensor helps the control board determine when to initiate or cease burner operation, ensuring the boiler responds accurately to heating and hot-water demands. A faulty flow sensor can lead to ignition issues, incorrect heat delivery or boiler lockouts, so replacing it with the correct specification part is key to restoring reliable performance.

This flow sensor is compatible with Worcester Bosch Junior and RD series boilers that reference part number 87161461640 in their parts documentation. To ensure proper fit and operation, always check the part number on your existing sensor or consult your boiler’s service information before installation, as correct matching affects system control behaviour.

Supplied ready for direct replacement, the 87161461640 flow sensor integrates seamlessly with the boiler’s existing pipework connections and electrical interface without modification. Choosing this genuine Worcester Bosch flow sensor helps restore accurate water-flow detection and dependable boiler response in compatible Junior and RD appliances, supporting efficient and consistent heating performance
