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.

Look for the model PM-02 and the reference Vaillant 0020045489; this unit also shows 3034 0083 V and 0020045379.
Look at the PCB code: TL-G1A and A1133-G1A.00200453C. The TL-G1A alone is not enough: another Vaillant board (0020045430) also has it.
Don't confuse it with 0020136649, the PCB that the spare parts lists provide for the VMW 21/245/4-5 and the VCW 195/245/4-5: it is a different code.
Check the model of your boiler on its rating plate: Registered confirmation: the VMW ES 21/245/4-5 R3.
If they match, call us at 911 17 77 77 with the model of your boiler.

Diagnosis and fault codes

Symptoms that require diagnosis in the Vaillant.

Common symptoms and faults

01
The boiler does not start or shuts down, with the warning F28 or F29.
Cause: Gas supply, ionization electrode or ground connection.
Have a technician check it. Do not touch the gas valve.
02
The boiler detects flame with the gas valve closed: warning F27.
Cause: Ionization electrode, faulty PCB or gas solenoid.
It is a security fault. Have a technician check it immediately.
03
The boiler locks out with the warning F61 or F62: fault in the gas valve or in the PCB.
Cause: Faulty wiring or gas valve, or a malfunctioning PCB.
Do not manipulate it. Have a technician check it.
04
The boiler displays the warning F63: memory fault of the PCB.
Cause: Faulty PCB.
Have a technician check it. It may be necessary to replace the PCB.

Vaillant fault codes that require diagnosis

Code	Fault	Technical checks
F27	Flame detected with the gas valve closed.	It is a safety fault. Have a technician check it immediately. Point to the ionization electrode or the PCB.
F28	Ignition fault: the appliance does not start after several attempts.	Have a technician check it. Focus on the gas supply, the ignition electrode, or the PCB.
F29	Flame loss during operation; the reignition fails.	Have a technician check it. Focus on the gas supply, the ionization electrode, or the grounding of the appliance.
F26	Stepper motor current of the gas valve not plausible.	Have a technician check it. Focus on the gas valve, its wiring, or the PCB.
F49	Low voltage on the eBUS (thermostat or controller line).	Check the wiring of the thermostat. If the warning returns, have a technician check it. Point to the communication PCB.
F61	Fault in the gas valve regulation.	Do not manipulate it. Have a technician check it: it could be the wiring of the gas valve or the PCB.
F62	Delay in closing the gas valve: the flame takes time to extinguish.	Have a technician check it. It points to leaks in the gas valve or the PCB.
F63	Fault in the memory (EEPROM) of the PCB.	Have a technician check it. The PCB may need to be replaced.
F64	Fault in the electronic system or in the sensors.	Have a technician check it. It points to the PCB or a short circuit in a supply or return sensor.
F65	Electronic system temperature too high.	Have a technician check it. It points to external heat on the PCB or a faulty PCB.
F67	Flame control signal out of limits (0 or 5 V).	Have a technician check it. Point to the PCB.
F20	Safety temperature limiter activated: overheating.	Do not reset it over and over again. Have a technician check it. If the warning returns, it may be due to a lack of water circulation, not 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.

Before purchasing

Not compatible or excluded: Vaillant VCW 195/4-5 R1 — It has a different PCB: 0020136649 (spare parts list and Vaillant catalog). It provided 0020045489 for the "VCW DE 195/4-5 R1".
Do not confuse: 0020136649 — Printed circuit board 0020136649 according to the PDF for the VMW 21/245/4-5; it lists it as "MODULO VAILLANT 0020136649" for the VMW 21/245/4-5 and the 21/245/4-5 R3; for the VCW 195/4-5 R1 and 245/4-5 it appears as "Leiterplatte, Heizwert low NOX" (and Vaillant spare parts catalog) — It is another code. Cite both in the title of its technical sheet without explaining the relationship; no other connects them.
Do not confuse: 0020045430 — Main PCB Vaillant with the marking TL-G1A on its circuit (in the repair forum of an atmoTEC pro) — It is another part number: the TL-G1A alone does not identify this PCB. Compare with 0020045489.
0020136649, VMW 21/245/4-5, VCW 195/245/4-5
To confirm: Workshop: VMW ES 21/245/4-5 R3. External: and it gives 0020045489 as Vaillant PCB; none link it to the VMW and the spare parts lists provide for it and for the VCW 195/4-5 R1 the 0020136649.

Frequently Asked Questions

Frequently asked questions: Vaillant

Where is the code for this PCB and what other markings should I compare?

The PCB is marked PM-02, the Vaillant reference 0020045489 and 3034 0083 V; it also shows 0020045379. The printed circuit board has TL-G1A and A1133-G1A.00200453C. First, compare 0020045489 and PM-02 with those on your board.

Is it compatible with my Vaillant VMW ES 21/245/4-5 R3?

Yes. Confirmation registered: this PCB (0020045489, PM-02) for the VMW ES 21/245/4-5 R3. Without additional external confirmation, it links that code to that boiler: it lists it as "MODULO VAILLANT 0020136649" for the VMW 21/245/4-5 and the 21/245/4-5 R3, and a spare parts PDF provides for the VMW 21/245/4-5 the printed circuit 0020136649, which is another code. Compare the code marked on your PCB.

Is 0020136649 the same as 0020045489?

without additional confirmation, the equivalent declarations are open. The 0020136649 is listed as "Printed circuit" in the breakdown of the VMW 21/245/4-5 (PDF) and as "Leiterplatte, Heizwert low NOX" in the lists of the VCW 195/4-5 R1 and 245/4-5 and in the Vaillant spare parts catalog. It is registered as "MODULO VAILLANT 0020136649" for the VMW 21/245/4-5 and the 21/245/4-5 R3, without stating that it is a printed circuit. It cites 0020045489 and [20136649] in the title of its technical sheet without explaining the relationship.

Is it compatible with other Vaillant boilers, such as the VCW 195/4-5 R1?

only the VMW ES 21/245/4-5 R3 has been confirmed. Specifically for the "Steuerung Leiterplatte 0020045489" for a VCW DE 195/4-5 R1, but the spare parts list and catalog from Vaillant indicate 0020136649 for the VCW 195/4-5 R1. We do not consider it valid: compare codes or call 911 17 77 77.

What do the codes PM-02, TL-G1A, and 3034 0083 V mean?

PM-02 is the model marked on the plate and 0020045489 is its Vaillant reference. TL-G1A and A1133-G1A.00200453C are codes from the PCB. The TL-G1A is not exclusive: a repair forum lists it alongside 0020045430, another Vaillant board. Without additional confirmation, 3034 0083 V or 0020045379 are not explained.

What should I check before installing it?

Their terminals are printed with 21V, 230V~, RT24V, RT230V~, and BUS, with a thermostat input of 24 V DC or 230 V AC. Note which terminal each wire goes to and check the F2A 250 V fuse before replacing the PCB.

Who should install it?

A qualified technician: the PCB operates with a 230 V AC supply and controls a gas boiler. Disconnect the boiler from the power supply before opening the control box.
