Guide

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.

Check the printed circuit board of your PCB: it should be marked with 734766, V064E, and model PM-02.
Look for the label with 00712027 and compare it; TC-AE and TL-AE/66 are also marked on the plate.
In the breakdown of the VMW 242/2-5 R3, code 0020034604 is listed as the support for the PCB. It is not on the label of this board: always compare 734766 and 00712027.
if they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.

Diagnosis and fault codes

Symptoms that require diagnosis in the Vaillant.

Common symptoms and faults

01
Erratic fault codes on the display without apparent cause.
Cause: To be confirmed: for the PCB 00712027.
02
Sudden resets during daily operation.
Cause: It is another symptom that is attributed to the PCB.
03
Stuck relays or burnt traces on the PCB.
Cause: They are visible at first glance: check the condition of the relays and the traces.
04
The boiler does not ignite or respond to any commands from the control panel.
Cause: for the PCB 00712027 (VMI 280-7). First, check that there is voltage reaching the board.
05
The boiler does not ignite: after three attempts without a flame, the fault code F.28 appears and it goes into fault mode.
Cause: Gas shortage or ignition failure, faulty electrodes or damaged PCB.
If it repeats, have a technician check it. Do not attempt to reset multiple times in a row.
06
The boiler shuts down during operation and the restart fails (fault code F.29).
Cause: Temporary gas cut, gas recirculation, condensates, or faulty grounding.
Have a technician check it.
07
The gas valve does not activate: the boiler stops with fault code F.61.
Cause: Fault in the wiring or in the coils of the gas valve, or faulty PCB.
Have a technician check it.
08
The boiler does not ignite: ignition attempts unsuccessful.
Cause: Insufficient gas or air in the pipe, electrode or ignition cable, electronic igniter or faulty electronic system.
Press Reset once. If it doesn't start, have a technician check it.
09
The boiler does not ignite: it does not detect a flame during the ignition phase.
Cause: Low gas pressure, faulty electrode or ignition transformer, or air in the gas supply.
Press the fault reset button for more than 3 seconds (a maximum of 3 times, according to the manual). If it still does not turn on, have a technician check it.
10
The flame goes out during operation and the reignition fails.
Cause: Interrupted gas supply or poor grounding.
Have a technician check it.

Vaillant fault codes that require diagnosis

Code	Fault	Technical checks
F.28	Start-up fault: after three attempts without flame, the boiler goes into fault.	If it repeats, have a technician check it: it could be the gas, the electrodes, or the PCB.
F.29	Flame loss during operation and failed reignition.	If it repeats, have a technician check it: it could be the gas supply, the flue gas recirculation, the grounding, or the ignition.
F.61	The gas valve does not activate properly: fault in the wiring, coils, or PCB.	Have a technician check it. Point to the PCB if the wiring of the gas valve is correct.
F.62	The gas valve takes time to close after the flame goes out.	Have a technician check it: it could be the gas valve, the electrode, or the PCB.
F.63	Fault in the memory of the PCB (EEPROM).	It usually points to the PCB: have a technician check it.
F.67	The flame signal is not valid: fault in the electronics or ionization.	If it goes out when turning on, have a technician check the PCB and the ionization.
F.20	The safety limiter has been activated due to temperature: the supply or return sensor has exceeded the maximum.	Check that there is water in the circuit and that the pump is circulating. If the flow sensor is poorly connected or faulty, have a technician check it.
F.27	There is a flame signal with the burner off.	A technician should check it: there may be a gas valve that is not closing or a faulty flame controller.
F.60	Gas valve fault: valve cable short-circuited, or defective valve or main PCB.	Have a technician check it. If the gas valve and its wiring are fine, it could be the PCB.
F.13	Short circuit in the temperature sensor of the accumulator.	Have a technician check it: it could be the accumulator sensor or its wiring. With a faulty sensor, the accumulator does not recharge in time.

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

To confirm: These symptoms come from the commercial text, not from a technical document: they are not enough to declare the PCB faulty.
To confirm: Vaillant VMW 24/282-5 R1 — 1 origin: (00712027)
To confirm: Vaillant VMI 280-7: and of (00712027)
To confirm: Vaillant VMI 320-7 — 1 origin: (00712027)
To confirm: Vaillant VMW 282/2-5 R1 — 1 origin: (00712027)
To confirm: Vaillant Turbomax Plus 824E / 828E — 1 origin with 734766 (B2B). 130806, which links to 734766, appears as PCB of Turbomax Plus in the Vaillant catalog and in others, without 734766.
Do not confuse: 0020034604 — "PCB support" in the breakdown of the VMW 242/2-5 R3 (pos. 11, control box) — It does not appear on the label of this PCB. as a board (families VUW and VU, and a technical sheet of VMW 242/2-5 R3), but none mention 734766 or 00712027.
Not confirmed: 734766 and 00712027: are marked on the same PCB. The spare parts catalog of Vaillant (840038.02) lists 130806 as the PCB for the VUW 242/2-5 and 282/2-5 (Turbomax Plus), without mentioning 734766. B2B links 130806 and 734766.
To confirm: they provide 00712027 as the PCB and one 734766, without joining them. Discrepancy: the breakdown of the VMW 242/2-5 R3 lists 0020034604 as the circuit support, but as a PCB; two link it to the previous code 130806, PCB of Turbomax Plus in the Vaillant catalog.
Pending confirmation of registered applications by model, variant, or programming: Vaillant VMW ES 242 2-5 R3.

Frequently Asked Questions

Frequently asked questions: Vaillant

Where is the code for this PCB and which one should I compare?

On the printed circuit board, 734766, V064E, and PM-02 are marked. The label shows 00712027 (on one unit, with the barcode 92 00712027 008 148646 3). First, compare 734766 and 00712027; TC-AE and TL-AE/66 are also marked on the board.

Is it compatible with my Vaillant VMW ES 242 2-5 R3?

The compatibility of this variant is pending confirmation. Registered: for the VMW ES 242 2-5 R3 and also for ETN-AE, TC-AE, and TL-AE/66. Additionally, the 00712027 for the VMW 242/2-5, although without indicating the R3 version.

What is the difference between 734766 and 00712027?

Both are on the same PCB: 734766 is the circuit code and 00712027 is the label code. Without additional confirmation, they are linked to each other. B2B lists the PCB 734766 with 130806 (Turbomax Plus 824E and 828E); the Vaillant spare parts catalog lists 130806 as the PCB for the VUW...-5 without mentioning 734766. They list 00712027 as the Vaillant board.

Is it the same part as 0020034604 from the parts list?

We do not affirm this. The breakdown of the VMW 242/2-5 R3 lists 0020034604 as "PCB support" (pos. 11, control box) and that code is not on the label of this board. As for the board: a distributor applies it to the VMW 242/2-5 R3 and the others to the VUW and VU families. Two provide it as a substitute for the 130806, which B2B lists alongside the PCB 734766. Not confirmed: 734766 or 00712027 with 0020034604: always compare 734766 and 00712027.

Does it work for other Vaillant models, such as the VMW 24/282-5 R1 or the VMI 280-7?

The compatibility of this variant is pending confirmation. It is yet to be confirmed. The 00712027 is listed for the VMI 280-7, and for the VMW 24/282-5 R1, the VMI 320-7 and the VMW 282/2-5 R1 only. The B2B sheet for the 734766 mentions the Turbomax Plus 824E and 828E. Call us at 911 17 77 77 with your boiler model.

What symptoms point to this PCB and what should I check beforehand?

To confirm: erratic fault codes, sudden restarts, stuck relays or burnt tracks, and a boiler that does not respond to the panel. For the latter case, it indicates to first check that the correct voltage is reaching the input of the PCB.

Can I install it myself?

The PCB has terminals for 230 V (L and N) and a transformer of 230 V~ · 50-60 Hz. It must be installed by a qualified technician.
