Guide

How to check if ref. 0020028476 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Look for the printed circuit board marked TM-G1C V132 and, next to it, G1C 0020045430. It should also include PM-01, TL-G1C, and 8483 0009 R.
Check the transformer on the PCB: it has Z10007 and 0020018299.
Compare the burner: brand +, 7, 8, 9, 1, L, N, 3, 4, 5, with L230V and an auxiliary voltage of 5 V.
Do not rely solely on the number 0020045430: in another way. Compare the marking TM-G1C V132.
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 0020028476

Common symptoms and faults

01
The boiler does not ignite or does not respond to any commands from the thermostat.
Cause: It is associated with this PCB.
02
Erratic and intermittent fault codes appear on the screen.
Cause: It also associates that.
03
Stuck relays that prevent the burner from starting.
Cause: It is listed among the faults.
04
The boiler experiences continuous resets during the operating cycle.
Cause: Does it include that among the signals?
05
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.
06
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.
07
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.
08
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.
09
The boiler does not ignite: after three attempts, F.28 appears and it goes into fault.
Cause: No flame during ignition: gas, electrodes, ionization or PCB.
Check that the gas valve is open. If it still does not ignite, have a technician check it.
10
The boiler shuts down during operation and does not restart; fault code F.29 appears.
Cause: The flame goes out: gas cut-off, flue gas recirculation, incorrect grounding, or ignition transformer failure.
Reset a maximum of three times. If it repeats, have a technician check it.
11
The boiler stops due to lack of water and fault code F.22 appears.
Cause: Low water in the unit, faulty water pressure sensor or loose cable.
Fill the installation according to the manual and bleed the radiators. If the pressure drops again, have a technician check it.
12
When starting the heating, F.75 appears and the boiler does not work.
Cause: Faulty pressure sensor or recirculation pump.
Check the pressure and bleed the radiators. If it continues, have a technician check it.
13
F.61 or F.62 appears and the boiler locks out.
Cause: Gas valve, its wiring or the electronics are faulty.
Do not reset multiple times. Have a technician check it.

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.
F.22	Lack of water or filling pressure too low. The boiler goes into fault.	Check the filling pressure on the manometer and refill according to the manual. If the pressure drops again, there is a leak or a fault with the pressure sensor or the cable: have a technician check it.
F.75	When starting the pump, no pressure increase is detected in the circuit.	Check the pressure and bleed the radiators. If the fault code persists, it points to the pressure sensor or the pump: 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.
