If it fails, the element does not switch, resulting in a lack of heating or hot water. This motor is compatible with models such as the Isomax C 30, Condens F 35-B, and F 35 H-MOD, among others. It is recommended to replace it when switching problems or loss of functionality occur in the heating system.

How to check if ref. 0020016182 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 0020016182. 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 motor 0020016182 resolves.
The motor drives the corresponding component of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
One or more radiators are not heating, or the entire heating system is providing less heat than usual.
Cause: This pump is in direct contact with the water in the circuit; if it doesn't move it, the heat doesn't reach the radiators properly.
Touch the body of the boiler during a heating cycle: if it is cold and silent instead of warm and with a slight vibration, it is a clear indication.
- 02
A buzzing can be heard in the motor area without any noticeable movement or added heat.
Cause: The motor tries to start but the shaft does not turn, which is common when it has been idle for a while and gets stuck due to lime or sediment from the water.
With the boiler turned off and cold, try to turn the shaft by hand through the front slot if it has one, before replacing it.
- 03
There is moisture or dripping around this part.
Cause: The seal that separates the electrical part from the water in the circuit wears out over time and starts to leak.
Dry the area well and check after a heating cycle to confirm that the moisture reappears right there.
- 04
After a long period of not using the boiler, it is difficult for the heating to start.
Cause: The limescale from the water deposits on the rotor during shutdown and increases the resistance to rotation.
Before replacing it, gently force the rotation by hand to loosen the rotor and try starting it again.
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.
