Sika Flow Switch for Intergas Kombi Kompakt HR 28/24 Boiler
The Sika flow switch for the Intergas Kombi Kompakt HR 28/24 boiler is a flow detector that is responsible for detecting the flow of water when a tap is opened, which activates the ignition to produce domestic hot water. When it fails, you will notice that hot water does not come out even when the tap is open, which may be associated with fault codes such as "Temperature too high" or "S1 sensor fault." This flow switch is compatible with other models in the Intergas Kombi Kompakt HR range, such as the HR 36/30, among others. It should be replaced when these symptoms of lack of hot water occur.

How to check if ref. 972630 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 972630. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the flow meter 972630 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
When opening the hot water tap, the boiler does not start the burner.
Cause: The flow switch does not detect the incoming flow and does not allow the boiler to ignite.
Check the water inlet pressure and the filter before the pressure switch before replacing it.
- 02
The burner turns on and off several times in a row while the water is running.
Cause: The signal from the flow switch arrives intermittently, usually due to scale or dirt inside it.
Check if the water flow is stable and sufficient, without pressure variations, before replacing the part.
- 03
The heating also doesn't start even though the boiler is in that mode.
Cause: In this model, the flow switch also controls the water flow for the heating circuit.
Confirm with the manometer that the installation has sufficient pressure before blaming the flow switch.
- 04
The hot water comes out with less pressure than normal and sometimes it doesn't heat up.
Cause: A partial or forced turn of the internal mechanism may result in an insufficient flow reading to activate the burner.
Clean the inlet filter and bleed the air from the system before considering that the part is faulty.
Fault codes Intergas that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 1 | Temperatura demasiado alta | The flow switch can get stuck and not change state; the controller keeps the burner without the expected flow rate, causing overheating. Verify that the flow switch switches with actual flow (5 VDC signal/continuity) and does not remain closed/open. |
| 11 | Sensor S1 fault | If the flow switch does not disconnect (remains closed), the controller detects an incoherent state linked to S1 and generates this alarm. Verify that when the flow stops, the flow switch opens and its signal reaches the PCB (≈5 VDC); clean or replace if it is stuck. |
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.
