How to check if ref. 3003200026 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 3003200026. 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.

Symptoms and faults that the heat exchanger 3003200026 resolves.

The plate heat exchanger transfers heat to the domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The hot water takes a long time to come out or it cuts off in the middle of the shower.

  Cause: Lime deposits clog the channels of the heat exchanger, causing the water flow to be irregular.

  Check if the cut matches the minimum ignition flow rate: if the flow increases and the boiler restarts, it may be another fault, not the heat exchanger.

• 02

  The flow of hot water has decreased significantly, even though the taps and shut-off valve are fully open.

  Cause: Limescale reduces the internal diameter of the heat exchanger channels, constricting the water flow.

  First, check the cold water inlet filter of the boiler, as it often gets clogged and causes the same symptom.

• 03

  Water is dripping from underneath the heat exchanger or its connections.

  Cause: The PCBs can crack due to thermal fatigue and start leaking water outside the circuit.

  Dry the area well, start the boiler, and locate whether the dripping originates from the joints of the connections or from the control board itself.

• 04

  It is noticeable that the boiler consumes more gas than usual to provide the same domestic hot water.

  Cause: With less useful exchange surface due to the scale, the boiler requires more time and power to reach the same temperature.

  Compare the time it takes to heat now versus before, and check if it coincides with a hard water area.

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.
