Restore Instant Hot Water: Genuine Vaillant Flow Sensor 103429 for Reliable Performance

A cold surprise when expecting hot water is a common sign of boiler trouble. If your Vaillant boiler isn't delivering hot water on demand, a faulty flow sensor could be the issue. This genuine Vaillant Flow Sensor 103429 is essential for signalling your boiler to provide hot water when you need it.

Your Hot Water Command: The Vaillant Flow Sensor Explained

The Vaillant Flow Sensor is a vital component in your Vaillant boiler, triggering your domestic hot water. When you open a hot tap, this sensor detects water movement, usually via an internal turbine. This signals the boiler's main control (PCB) that hot water is required, prompting the boiler to fire up. If your Vaillant Flow Sensor 103429 is faulty, you might experience no hot water, an intermittent supply, or the boiler might not react to an open tap.

Choosing this genuine Vaillant Flow Sensor 103429 ensures it meets Vaillant's precise specifications, guaranteeing a perfect fit and reliable communication with your boiler. This is crucial for consistent performance and avoids issues common with non-genuine parts, like inaccurate readings or a shorter lifespan. Using the correct part helps maintain your boiler's efficiency and safety.
