Plate Heat Exchanger for Boiler ZWBC 30-2 C 23 Ref. 87161066850
The Junkers boilers from the Cerapur Comfort ZWBC range use the heat exchanger for boiler ZWBC 30-2 C 23, which is responsible for transferring heat from the primary circuit to the domestic hot water instantly. When this part fails, you will notice that the water comes out lukewarm or with fluctuating temperature, and the flow of DHW decreases. It is compatible with models such as ZWBC24-2C, ZWBC28-2C, ZWBC30-2C, among others. A technician must confirm through diagnosis whether it is necessary to replace it when you start experiencing these symptoms.

How to check if the ref. 87161066850 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 87161066850. If it is not visible, do not identify the part from 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 87161066850
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
There is a drip or moisture under the boiler that is not clear where it is coming from.
Cause: The heat exchanger plates are not sealed properly, allowing water to escape through the body of the part or its gasket.
Dry the area, leave paper underneath for a while with the boiler running, and check if the dripping originates right there.
- 02
The boiler is taking longer to provide hot water and it seems to be consuming more than before.
Cause: The plates with accumulated scale hinder heat exchange, causing the boiler to work harder.
Time how long it takes for hot water to come out and compare it with the boiler filter when it is clean, to rule out that the delay comes from there.
- 03
The hot water comes out in bursts, alternating between cold and hot without maintaining a stable temperature.
Cause: Partially clogged plates due to scale cause an irregular water flow, resulting in temperature fluctuations.
Open the tap to maximum flow and then to minimum: if the fluctuation improves with less flow, it indicates a partial obstruction in the plates.
- 04
The pressure in the system rises on its own over the days.
Cause: An internal micro-leak in the heat exchanger allows water to pass from one circuit to another, increasing the pressure.
Note the pressure before and after using hot water for a couple of days, without touching the filling valve.
Junkers fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| E2 | Faulty supply temperature sensor | The supply temperature sensor is faulty. This may cause the boiler to malfunction. If you notice that the hot water does not reach the desired temperature, it could be that the plate heat exchanger is affecting the water circulation. |
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.
