Airsol Flow Meter Sensor HKB 224 Ref. 3003201466
The Airsol Sensor HKB 224 flow meter detects the flow of water when a tap is opened and commands the ignition to produce domestic hot water. When it fails, you will notice that no hot water comes out even when the tap is open. This sensor is compatible with boilers from the Airsol HKB range, such as the HKB 224 and HKB 224 C models, as well as with other models from the brands Demrad, Heatline, and Glowworm. It should be replaced when there are issues with hot water production.

How to check if the reference 3003201466 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 3003201466. 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 3003201466 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 ignite the burner.
Cause: The flow detector does not inform the control board that there is flow, so the boiler does not heat.
Open the tap fully and check if you notice weak pressure or flow in the mixture before changing the sensor.
- 02
The water comes out hot and cold intermittently while the tap is open.
Cause: An irregular flow reading causes the boiler to modulate the burner in an unstable manner.
Check that the water inlet filter is not partially blocked by scale or debris before replacing the sensor.
- 03
The boiler takes a long time to provide hot water or only works with the tap fully open.
Cause: The flow detector requires a minimum flow rate to activate, and if it is dirty or damaged, it demands a higher flow rate than normal.
Check the incoming water pressure and the condition of the filter before declaring the part defective.
- 04
The boiler provides hot water in some faucets of the house and not in others, inconsistently.
Cause: This usually points to insufficient flow at that point in the installation rather than the sensor, although a turbine blocked by scale can exacerbate it.
Test the faucet closest to the boiler with the maximum flow possible to rule out that the problem is with the installation before replacing 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.
