Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by 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.

Diagnosis and fault codes

Symptoms that require diagnosis in the circulation pump

The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:

Common symptoms and faults

01
The boiler starts normally, but the radiators remain cold.
Cause: The burner works, but the water does not circulate through the heating circuit.
Touch the supply and return heating pipes; if there is a large temperature difference between them, the pump is not moving water.
02
There is noticeable noise or vibration in the pump while operating.
Cause: The impeller may be partially blocked by scale or the bearing worn out.
Listen to see if the noise changes when adjusting the pump speed before deciding to replace it.
03
The pump does not start or gets stuck, especially after stopping the heating for a while.
Cause: The shaft gets stuck due to sediment when it hasn't been turning for a while.
Try to free the shaft with the front screw of the motor before buying a new pump.
04
Water or moisture appears in the area of the pump shaft.
Cause: The mechanical seal loses tightness with use and starts to leak gradually.
Dry the area and check in cold if the leak reappears before replacing the pump.

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.
