Diagnosis and fault codes

Symptoms that require diagnosis in the Vaillant 0020028476

Common symptoms and faults

01
The screen turns off and the boiler does not work.
Cause: To confirm: (.md) indicates a faulty PCB and attributes it to voltage spikes and storms.
02
It won't start and a forum mentions an F28 that won't reset (a case, atmoTEC pro).
Cause: The author reviewed the reset circuit on the bench and, apparently, the PCB had gotten wet: he found a corroded track connection and bridged it.
03
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.
04
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.
05
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.
06
The boiler does not ignite or turns off during operation, with the warning F28 or F29.
Cause: Ignition or flame failure: gas, electrode or gas valve.
Check that the gas valve is open and reset once. If it returns, have a technician check it.
07
The boiler locks out with the warning F61 or F62: fault in the gas valve or in the PCB.
Cause: Faulty gas valve or PCB with fault.
Do not manipulate it. Have a technician check it.
08
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.
09
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.
10
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.
11
The boiler does not ignite and locks out with F28 or F29.
Cause: Flame is not detected when igniting, or the flame goes out and does not reignite: lack of gas, ignition failure, or electrode fault.
Check that the gas shut-off valve is open. If it remains blocked, have a technician check it.
12
The boiler does not ignite and shows F.28.
Cause: After three failed ignition attempts, the device goes into fault.
It could be related to the gas or the electronics.
13
The boiler shuts down during operation and displays F.29.
Cause: The flame goes out and the reignition does not occur properly.
Have a technician check it.

Vaillant fault codes that require diagnosis

Code	Fault	Technical checks
F.28	Ignition fault in the atmoTEC pro: the burner does not ignite after five attempts and the unit locks out.	It is not solely a diagnosis of a faulty PCB. The unit only attempts to ignite again after a manual reset. If the fault code repeats and you have doubts about whether the cause is the PCB, please consult us with the model of your boiler.
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.
F27	Flame detected with the burner off.	It is a security fault. Have a technician check it immediately. Focus on the electrode, the gas valve, or the PCB.
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.
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.
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

To confirm: (.md) attributes several screen fault codes to a faulty PCB, without an official table to confirm them. Do not take them as proof of the PCB.
According to the thread author, a good PCB without wiring displays errors on the screen that include F28: seeing them on the bench does not prove that it is faulty.
To confirm: Vaillant turboTEC pro and plus, atmoTEC plus — with part code: (0020028476). .md cites the universal PCB 0020092371 for Pro and Plus, without linking it to 0020035427; without specific model.
To confirm: Vaillant VUW 180, 182, 200, 202, 240 and 242 (3-3 M), VU 240/3-3 M, VUW GR 242/4-3B and 282/4-3B: .md, without model code. For the VUW 242, the circuit 0020034604: unresolved contradiction; compare the code.
Not compatible or excluded: Vaillant Turbomax VUW 242/1E (1998-2001) — It has a different PCB: PCB 130438
Not compatible or excluded: Vaillant VUW 242/5-3, 282/5-3, 242/5-5 and 282/5-5 — They have a different PCB: 0020202559
Do not confuse: 0020202559 — PCB for turboTEC and atmoTEC manufactured since 2015, with other parameters — .md and they provide it for that generation; it is not a proven equivalent.
Without an official document that matches these codes: compare the marked ones.
Two forums connect 0020035427 with the atmoTEC pro (.ws with PM-02; with PM-03). It connects through 0020028476, the reference. .md gives PM-03 for the turboTEC/atmoTEC family. Discrepancy PM-02/PM-03 unresolved; no official breakdown.
Pending registered applications to confirm by model, variant, or programming: Vaillant VMW ES 23/362 3-5 RV (TURBOTEC).
