Installation (Setup)
Important Safety Information: Installation of boiler components should only be performed by a qualified and certified heating engineer. Incorrect installation can lead to serious injury, property damage, or boiler malfunction. Always disconnect the boiler from the main power supply and ensure the system is depressurized and drained before attempting any work.
- Preparation: Ensure the boiler is completely isolated from the electrical supply and the gas supply is turned off. Allow the boiler to cool down.
- Drain System: Partially or fully drain the boiler system as required to access the flow sensor.
- Locate Old Sensor: Identify the existing flow sensor turbine within your Vaillant boiler. Refer to your specific boiler model's service manual for its exact location.
- Remove Old Sensor: Carefully disconnect any electrical connections and plumbing fittings attached to the old sensor. Remove the old sensor, noting its orientation.
- Install New Sensor: Insert the new Vaillant Flow Sensor Turbine (Part No. 20029604) in the correct orientation. Ensure all seals are properly seated to prevent leaks.
- Reconnect: Reconnect all electrical wiring and plumbing fittings securely.
- Refill and Bleed: Refill the boiler system and bleed any air from the system according to your boiler's main instruction manual.
- Test: Restore power and gas supply. Test the boiler's operation, checking for leaks and proper hot water function.
Operating Instructions
The flow sensor turbine operates automatically as an integral part of your Vaillant boiler's control system. It detects water flow, signaling the boiler to initiate heating or hot water production as needed. No direct user interaction is required for its operation. Once correctly installed, the boiler's existing controls will manage the function of this component.
Maintenance
The flow sensor turbine itself typically requires no direct user maintenance. However, regular professional servicing of your Vaillant boiler system, as recommended by the manufacturer (usually annually), will ensure all components, including the flow sensor, are functioning correctly. This includes checking for debris or blockages that might affect water flow and sensor accuracy. A qualified engineer can inspect the sensor for wear or damage during routine service.
Troubleshooting
If your Vaillant boiler exhibits issues such as inconsistent hot water temperature, failure to ignite for hot water, or displays error codes related to water flow, the flow sensor turbine may be a contributing factor. Before assuming the sensor is faulty, ensure other common issues are ruled out (e.g., low system pressure, closed valves).
Common Symptoms of a Faulty Flow Sensor:
- No hot water, but central heating functions normally.
- Boiler fires intermittently or cycles on and off when hot water is demanded.
- Boiler displays a specific fault code related to water flow or hot water production.
Recommended Action:
- Consult your boiler's main instruction manual for specific error codes and their recommended solutions.
- Contact a qualified and certified heating engineer for professional diagnosis and replacement. Do not attempt to repair or replace this component without proper qualifications and safety equipment.
