How to check if ref. S5720200 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference S5720200. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the flow meter S5720200 resolves.

The flow meter detects the passage of water to activate the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  No hot water: the boiler remains in heating mode.

  Cause: The flow detector is not sending a signal, and the PCB does not detect the demand for domestic hot water.

  Before changing the part, make sure that the tap opens with normal flow and that there is no valve partially closed.

• 02

  The hot water cuts off and returns intermittently.

  Cause: Lime deposits in the internal mechanism cause the detector to occasionally lose contact.

  Disassemble the sensor and check if there is scale or dirt accumulated in the moving area.

• 03

  There is moisture near where the cold water enters the boiler that wasn't there before.

  Cause: The plastic body of the detector may crack over time and cause a leak.

  Dry the area and observe if moisture reappears after a while of use on the body of the part.

• 04

  A warning or fault code related to the domestic hot water circuit appears on the screen.

  Cause: Some PCBs interpret the detector as a digital signal and indicate anomalies if it fails or makes a false contact.

  Note the exact code and compare it with the manual before concluding that it is the sensor.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
