Flow Turbine Junkers/Buderus Logamax Plus GB042 - Ref. 8716011820
The flow turbine Junkers/Buderus Logamax Plus GB042 - Ref. 8716011820 acts as a flow switch or flow detector, detecting the passage of water when a tap is opened and activating the ignition to generate domestic hot water. If it fails, you will notice that hot water does not come out even when the tap is open. This part is compatible with boilers from the brands Junkers and Buderus, such as the Logamax Plus GB042 model and others like ZSC24-3MFA, ZSC30-3MFA, and ZWB28-3C, among others. It is recommended to replace it when you experience a lack of hot water when opening the tap.

How to check if ref. 8716011820 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 8716011820. 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 8716011820 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
The boiler does not ignite when requesting hot water.
Cause: The turbine does not spin when water passes through, and the sensor does not send the signal to the control board.
Open the hot water tap to a high flow rate and see if it starts: with low flow rates, many turbines do not detect the demand.
- 02
The hot water comes out irregularly.
Cause: The turbine spins irregularly due to the accumulation of scale or dirt on the blades.
Check for limescale in the water inlet filter before replacing the turbine; it is usually the most common cause.
- 03
The boiler shows a flow error.
Cause: The sensor does not generate pulses correctly and the control board believes there is no water flow.
Measure the incoming water pressure from the mains and ensure that the filter is not clogged before changing the sensor: without sufficient pressure, it does not detect flow.
- 04
The hot water comes out in bursts.
Cause: The turbine intermittently loses and regains the rotation signal due to a worn or stuck shaft.
Check if the cut coincides with drops in the general network pressure; if it disappears with high and constant pressure, review the installation before the turbine.
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.
