How to check if the ref. 9158624 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 9158624. If it is not visible, do not identify the part by its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis in the plate heat exchanger 9158624
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
Less hot water is coming out than expected, or the water is arriving lukewarm.
Cause: The accumulated limescale on the plates prevents heat from being transferred properly to the water.
Check if the water in the area is hard and if the boiler has received descaling maintenance recently.
- 02
A water leak is observed in the area where the heat exchanger is installed.
Cause: A joint or weld in the plate pack has lost its tightness.
Dry the area, turn on the boiler, and locate the exact point of the leak before replacing the part.
- 03
The heating circuit is losing pressure without any visible leaks outside the boiler.
Cause: An internal microcrack allows the water from the primary circuit to escape into the domestic hot water circuit.
Fill the circuit to the appropriate pressure and check if the pressure drops again in a few days, especially after using a lot of domestic hot water.
- 04
Do you notice a slight whistle when you request domestic hot water?
Cause: The accumulation of scale between the plates narrows the water passage and causes turbulence.
Check if the noise only occurs when requesting domestic hot water and not when the heating is on, to better identify the source.
Fault codes Cointra that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E80 | The legionella cycle is not completed and the boiler issues a warning. | The legionella cycle has not been completed. This may pose a health risk. Ensure that the plate heat exchanger is in good condition and allows for the proper heating of the water. |
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.
