Guide

How to check if ref. 9158878 is the part for your boiler

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

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 9158878. If it is not visible, do not identify the part from its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. 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 gas valve 9158878

The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler does not ignite and the click of the gas valve is not heard when starting.

    Cause: The ignition block is not receiving power to activate the gas valve coil.

    Measure with a multimeter if power is reaching the connector during the start attempt before replacing it.

  • 02

    The ignition intermittently fails: sometimes it lights and sometimes it doesn't.

    Cause: There is a poor connection in the connector, which may loosen or lose continuity due to the vibrations of the boiler.

    Check that the connector is properly seated in its housing and that the terminals are not loose or corroded.

  • 03

    A flame failure warning appears on the screen just when trying to start.

    Cause: The block does not activate the gas valve within the time expected by the control board, so the burner does not ignite.

    Reset the boiler and check if the warning appears at the same point in the cycle before changing the block.

Fault codes Cointra that require diagnosis

CodeFaultTechnical checks
A09Gas valve anomalyThe gas valve may be faulty or have interrupted actuator/wiring, preventing its opening or modulation; check the continuity of the wiring and power supply to the actuator and ensure that the valve opens on demand.
A16Gas valve anomalyThis symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement.
F50Gas valve anomalyModulating actuator error (wiring interrupted) or faulty valve; check continuity of the actuator/coil and control voltage, and replace the valve if it does not respond.
A62There is no communication between the control board and the gas valve.The valve may be faulty or not responding to the signal from the control board; check connectors and wiring between the PCB and the valve, presence of control signal, and replace the valve if it does not communicate.

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.
