How to check if ref. MU1011300 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 MU1011300. 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 burner MU1011300 resolves.
The burner performs the combustion of gas. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite on the first attempt and makes several attempts with a sparking noise.
Cause: The ignition arc is weak or irregular and does not always ignite the gas from the burner.
Check if the spark is continuous or intermittent; if it is intermittent, the fault is usually in the ignition system.
- 02
There is no spark or ignition sound when requesting heating.
Cause: The electrode or the internal transformer of the spark train has stopped generating the electric arc.
Check that the connector and the high voltage cable are properly secured before replacing the part.
- 03
The boiler locks out with an ignition fault or flame detection fault warning.
Cause: Without a reliable spark, the burner does not ignite and the system shuts down for safety after the allowed attempts.
Clean the electrode of any soot deposits and check its position before replacing the complete assembly.
- 04
There is a smell of gas for a few seconds after each failed ignition attempt.
Cause: The gas flows to the burner, but since the spark does not ignite, it remains unburned.
Check that the electrode is properly aligned with the burner and has not moved before considering the spark train faulty.
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.
