How to check if ref. MU0500117 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 MU0500117. 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 circulation pump MU0500117 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 boiler is working, but the water takes a long time to heat the radiators.
Cause: The impeller is blocked or rotates with difficulty and does not move enough flow.
Touch the pump casing with the boiler running to see if it vibrates or is completely stopped.
- 02
When changing the speed on the pump selector, there is no noticeable difference between the two positions.
Cause: One of the two windings of the two-speed motor has stopped working.
Test both positions of the selector with the boiler running and check if the noise or flow changes.
- 03
The pump does not start after being idle for a while, for example at the end of summer.
Cause: The shaft has seized due to sediment buildup during inactivity.
Try to manually free the shaft with a screwdriver in the front slot before replacing the pump.
- 04
There is a continuous noise or humming in the pump while the boiler is operating.
Cause: Air trapped in the circuit or a worn bearing causes the assembly to vibrate.
Bleed the heating circuit and check if the noise disappears before replacing the part.
- 05
Water appears at the base of the motor or dripping under the pump.
Cause: The mechanical seal no longer properly seals the rotating shaft.
Dry the area and check when cold if the moisture reappears right on the pump body.
Fault codes for Fagor that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F1 | Lockout due to ignition fault. | The gas valve does not open/modulate correctly and there is not enough flow to form/stabilise the flame; check the power supply to the solenoid valves (on/off and modulating), inlet pressure, and that the ramp delivers pressure when ignition starts. |
| F6 | Flame detection with the burner off (false flame/persistent flame). | The gas valve does not close completely and allows gas to pass, maintaining a flame when it shouldn't; check the valve's tightness at rest (manometer on the manifold) and ensure that when the demand is cut, the pressure in the manifold drops to 0 and there is no residual control voltage to the solenoid valves. |
| F10 | Fault in the control/closure of the gas valve. | Mechanical or electrical fault of the valve (coils, on/off solenoids, or control module); check coil continuity, control voltage during opening/closing, and response in self-test; if there is a stuck relay on the PCB, rule it out first. |
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.
