Baxi Roca Victoria 20/20 F Circulating Pump
The Roca Victoria 20/20 F circulator pump moves water through the heating circuit, ensuring that heat is distributed properly. When it fails, you will notice cold radiators, strange noises, overheating, or blockages due to lack of circulation. This part is compatible with the Victoria 20/20 F, Victoria 20/20, Victoria 20/20 SP GN models, among other Roca series. It is advisable to replace it if you experience any of these symptoms or if the fault code 50-60-90 appears, which indicates an open overtemperature thermostat.

How to check if ref. 7803036 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 7803036. 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 circulator pump 7803036 resolves.
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 radiators do not heat up even though the boiler turns on.
Cause: The pump is not circulating water through the heating circuit.
Touch the supply pipe and the return pipe: if there is no temperature difference, bleed the pump before replacing it.
- 02
There is no noticeable water circulation in the heating circuit.
Cause: The rotor may be stationary or rotating without sufficient force.
Check if the pump vibrates with the boiler on and bleed the air through the front screw before replacing it.
- 03
There is a noise or buzzing coming from the pump area.
Cause: Air in the rotor or a worn bearing causes the noise.
Bleed the air from the pump and the highest radiators; if the buzzing continues, the fault is with the pump.
- 04
The pump does not start.
Cause: The shaft may be seized due to sediment, especially after a long shutdown.
With the boiler turned off, try to manually unclog the shaft through the front plug before purchasing a new one.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 50-60-90 | Overtemperature thermostat open. | If the circulating pump is blocked/seized, there is no flow in the primary; the water does not dissipate heat, the boiler overheats, and the thermostat triggers 50-60-90. Check if the pump starts (noise/consumption), if the shaft turns after loosening the front cap, and that it receives voltage from the PCB. |
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.
