How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look for the designation FPPlatform8738713426 V12 variant0 on the label and the circuit code 8738713426 (also written as 8 738 713 426).
- Compare the relay on the PCB: HAHN Z10015, 8 738 703 049, and G21/17. These are the markings that have been read on this unit.
- Note the V12 review and variant 0: the marked codes do not alone certify compatibility with other variants, so compare the full designation.
- your boiler uses the control unit 8 738 723 206 from the official Bosch catalog, it is another code: compare the marked ones or send us a photo before ordering.
- they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you. Any questions? Send us a photo of your spare part label and the boiler's specification plate from the Contact section.
Symptoms that require diagnosis in the junkers
Common symptoms and faults
- 01
The spark jumps, but the burner does not ignite and the screen shows EA.
Cause: Lack of signal at the ionization electrode: dirt or moisture, air in the gas pipe, or lack of gas.
Check that gas and pressure are reaching, and inspect the ionization electrode and its cable. If everything is fine, have a technician check it.
Junkers fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| EA | No flame detected: missing signal at the ionization electrode. | Check that gas and pressure are reaching, the connection to the network, the ionization electrode and its cable. If everything is fine and the fault code persists, the PCB is suspect: have a technician check it. |
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.

Before purchasing
- Do not confuse: 8738723206 — Control unit of the WTD 18 AME 23 in the official Bosch catalog; it is sold as a PCB for that model in spare parts. — It is another code. Not confirmed: if it is the same part as 8738713426 with a different revision: compare before ordering.
- Do not confuse: 8738703049 — Number given for other parts: the main PCB FPAF 0113 (second hand) and a domestic hot water module (Australian). — On this PCB, it is the marked code of the relay, not the one for the PCB.
- They are marked on the part itself. Without additional external confirmation, they link it to a catalog reference. The official Bosch catalog lists another control unit for the WTD 18 AME 23, the 8 738 723 206: check the codes that should not be confused.
- Compatibility with the WTD 18 AME 23 registered. Without additional external confirmation, the code 8738713426 is not linked to this or any other boiler; the official Bosch catalog lists another control unit for that model, the 8 738 723 206.

Frequently asked questions: junkers
What is the Junkers 8738713426 PCB and how do I identify it?
It is a Junkers PCB with circuit code 8738713426 (also written as 8 738 713 426), revision V12 and variant 0. The marked designation is FPPlatform8738713426 V12 variant0. For comparison, also look at the relay on the board: HAHN Z10015, 8 738 703 049 and G21/17.
Is it compatible with my Junkers WTD 18 AME 23?
The compatibility of this variant is pending confirmation. Registered application: this PCB for the Junkers WTD 18 AME 23. Without additional external confirmation from those we have opened, it collects the code 8738713426, so we cannot provide you with an official catalog reference: compare the full designation and the relay of the PCB with yours.
Is it the same part as the control unit 8 738 723 206 from the Bosch catalog?
We don't know. The official Bosch catalog lists for the Hydrocompact WTD 18 AME 23 (item 7 736 502 445) the control unit 8 738 723 206, and on the official pages we have been able to read, the 8738713426 does not appear. Not confirmed: both codes. For other models, such as the WTD 18 AME 31, we do not have confirmation for this PCB. If your part has a different code, please send us a photo via Contact before ordering it.
What do the codes marked on the plate mean?
8738713426 is the circuit code (PCB), with revision V12 and variant 0. FPPlatform8738713426 V12 variant0 is the printed designation. HAHN Z10015 (model Z 10015), 8 738 703 049, and G21/17 are the markings on the relay of the board. They do not necessarily correspond to the reference of a kit nor do they guarantee compatibility with other variants.
Can I search for this PCB using 8738703049?
It's not the most reliable. On this PCB 8 738 703 049 is the marked code of the relay, not the one for the PCB. They use that number for other parts: a second-hand one lists it as the number for the main PCB FPAF 0113 and the Australian one associates it with a domestic hot water module. It's better to compare the complete designation FPPlatform8738713426 V12 variant0.
Does the V12 revision marked on the plate matter?
Our unit has revision V12 and variant 0. Without additional open confirmation, it explains what changes between revisions of code 8738713426, so we cannot say if another revision is interchangeable. Compare the full designation of your PCB, not just the number.
Who should install this PCB?
A qualified technician. It is a control board of a gas appliance, connected to the electrical network. Before touching anything, the electrical supply must be cut off and the gas closed.
