Cointra Edyco 21 EI PCB - Honeywell ECOINT00

The PCB Cointra Edyco 21 EI - Honeywell ECOINT00 is the component responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior. This part is installed in Cointra Edyco boilers, such as the ED 21 EI model, among others. A technician must confirm through diagnosis whether it needs to be replaced upon noticing these symptoms to avoid malfunctioning of the boiler.

Guide

How to check if ref. 9158792 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 9158792. 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 on the PCB 9158792

The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    When pressing the power button, nothing happens, neither the display nor the fan.

    Cause: The PCB is not sending power to start the boiler.

    Before replacing it, measure with the multimeter if the PCB is receiving mains power and check its fuse.

  • 02

    The display shows a fault, reset the boiler and it works for a while, then it fails again later with a different code.

    Cause: Changing fault codes are often due to an intermittent internal fault of the PCB.

    Note each code that appears over a few days: if it is not always the same, suspect the PCB.

  • 03

    You have changed the temperature on the living room thermostat and the boiler remains the same.

    Cause: The PCB is not interpreting the signal from the thermostat or the control.

    Measure the continuity of the thermostat cable up to the terminals of the PCB before replacing the board.

  • 04

    The circulation pump keeps running, even when there is no demand for heating.

    Cause: The relay on the PCB that controls the pump has stuck closed and is not cutting off the power.

    Disconnect the pump connector on the PCB; if there is still power at that output, the relay is stuck.

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.
