Filling Key Ferroli Cointra Domitop F 24 E Ref. I39811540

The filling key Ferroli Cointra Domitop F 24 E allows water to be replenished in the heating circuit to recover pressure. When it fails, the circuit cannot be refilled or it may continuously lose water, leading to an increase in pressure. This part is compatible with Ferroli boilers such as the Domitop F 24 E and other models in the range, as well as with Cointra boilers of the same series. A technician should confirm through diagnosis whether it needs to be replaced when you notice issues with filling the circuit or water leaks.

Guide

How to check if ref. I39811540 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 I39811540. 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 filling valve I39811540

The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The pressure in the circuit gradually drops, and it needs to be refilled every few days.

    Cause: The filling valve does not close completely and allows water to pass through at low pressure continuously.

    With the boiler cold, dry the body of the valve well and check a few hours later if humidity has reappeared.

  • 02

    Water droplets appear on the body of the valve even when it's not being refilled.

    Cause: The internal sealing gasket is worn out and the valve leaks even when the lever is closed.

    Press the lever all the way down until you feel the stop and check if the dripping stops.

  • 03

    The lever is hard to turn, feels stiff, or jerks abruptly when opening.

    Cause: Lime scale buildup in the internal mechanism, common in valves that haven't been moved for a while.

    With the boiler cold, move the lever several times from open to closed to see if it releases.

  • 04

    After refilling, the pressure gauge needle keeps rising on its own.

    Cause: The valve has been left partially open and continues to allow mains water to pass into the circuit.

    Ensure that the lever remains firmly in the closed position, without stopping halfway.

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.
