Cointra 3-Way Valve Kit Excellent Low NOx Ref. 39842111

When you turn on the tap or activate the heating, the Cointra 3-Way Valve Kit Excellent Low NOx Ref. 39842111 is responsible for directing the water between the heating circuit and the domestic hot water circuit. If this valve fails, you will notice that you have hot water but no heating, or that both circuits are mixing, causing a lack of comfort in your home. This component is compatible with Cointra Excellent Micro Low NOx boilers, among others. A technician must confirm through diagnosis whether it needs to be replaced if you experience these issues to restore the proper functioning of your system.

Guide

How to check if the part number 39842111 is the one 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 39842111. 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 3-way valve 39842111

The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler heats one circuit but not the other: heating yes, domestic hot water no, or vice versa.

    Cause: The valve shutter is not sealing properly in one of the two passages, causing the flow to be unevenly distributed among the circuits.

    With the boiler in DHW mode, check if the supply pipe to the heating system is completely cold; if it warms up a bit, the valve is not closing properly.

  • 02

    It takes a long time to switch between heating and domestic hot water.

    Cause: The internal mechanism moves with more resistance than normal, due to wear or limescale deposits in the body.

    Count the seconds from when you turn on the tap until hot water comes out; a delay that didn't exist before points to the valve, not the boiler.

  • 03

    Noise or rattling in the gas valve when changing position.

    Cause: The shutter hits its seat because the spring or the internal guide has lost precision.

    Locate whether the noise comes from the body of the gas valve and not from the circulation pump, by placing your hand on each component separately.

  • 04

    Water leak from the body of the gas valve.

    Cause: The internal gaskets degrade with cycles of heat and pressure and stop sealing between the body and the cover.

    Dry the area well and check after a while of operation; a leak that reappears at the same point confirms the gasket, not just a simple condensation drip.

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.
