How to check if reference 8708300269 V04 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Look for the printing on the PCB 8708.300.269 and revision V04. It appears on the label as 8708300269 V04.
- Check the HAHN transformer: it should have V17280 and 8707201044, with a primary of 230 V (terminals 9-14) and secondaries of 22 V · 33 VA (terminals 5-7) and 230 V · 3 VA (terminals 1-3).
- Look at the SCHRACK RT134024 relay (coil 24 V DC) and the connectors marked FAN and N/S.
- No la des por equivalente a la 87083001120, a la VL8738727277 ni a la 87072072950 (otros códigos): sin confirmación adicional abierta las une a este código.

Symptoms that require diagnosis in the junkers 8708300269 V04
Common symptoms and faults
- 01
The boiler does not detect the flame or the ionization intermittently fails.
Cause: Official manual Vulcano WTD 11/14/17 KME (2011), table 10: check the flue gas duct and the PCB; it indicates a fault in the electronic box as the cause. It does not specify a PCB reference.
- 02
Flame is detected with the device turned off.
Cause: Official manual 2019 of the Vulcano WTD 11/14-4 KME: check the electrodes and the cable, the flue gas duct, and the PCB.
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.

- These are general checks from the boiler manuals: none of the reviewed manuals mention reference 8708.300.269 V04, so they are not sufficient to diagnose this PCB.
- No confundir: 87083001120 — Placa del mando a distancia (Fernbedienung) que alemana da para las WTD 11 / 14 AM 1 E — Otro código, otra pieza y otro modelo (AM 1 E, no KME)
- No confundir: VL8738727277 — Módulo de la WTD14KME23 que lista portuguesa — Código distinto; la ficha no lo une a 8708.300.269 V04. Compara la serigrafía antes de darlo por equivalente
- No confundir: 87072072950 — Placa que para la WTD 14 KME; una de ellas cita también la 8738714938 — Otro código. Confirmación registrada: la 8708.300.269 V04 para esa caldera: compara la serigrafía de tu placa antes de pedir
- No confundir: 8708300212 — Módulo Vulcano-Junkers (también 87083002120) de la ZW23-1 S3705 portuguesa — Misma serie de numeración, pero otro código y otra caldera
- No confundir: 288.45.0018 — Módulo de encendido que para varias calderas WTD, entre ellas «WTD14» — Otra pieza (encendido); no es esta placa
- Casi todos son marcados leídos en la propia pieza; el 3-1393239-0 sale de la ficha del fabricante del relé. sin confirmación adicional externa abierta une estos códigos a un despiece Junkers: no los des por equivalentes a otras revisiones sin comparar.
- Compatibilidad con la WTD 14 KME registrada. sin confirmación adicional externa abierta une 8708.300.269 V04 con una caldera; otra placa para esa caldera.
- Aplicaciones registradas pendientes de confirmar por modelo, variante o programación: Junkers WTD 14 KME.
