Buderus Logomax GB022-24k: Addressing Error 6A Insufficient Ionization After Power Cuts

After today's numerous power cuts, there is a problem with the Buderus GB022-24k stove. After switching on, the stove tries to start heating and after a while the error "6A" appears.
"Insufficient ionization error" - what to do? Clean the combustion chamber? It was done about 2 years ago. Electrode to be replaced?

As you answered cleaning, the electrode is not necessarily replaceable, it is enough to clean it. Error 6A is also a power supply issue. Correct connection of the neutral phase and ground, check if necessary.

And cleaning helped.
I dismantled the entire burner chamber, cleaned this white carbon deposit from the coil and thoroughly rubbed the ionization sensor. The furnace started immediately. I have the electrical installation made in accordance with the art. I wonder whether to buy such a sensor in advance? Oh, my porcelain is ok, but the stamen itself is a bit worn out by my eye.

Added after 34 [minutes]:

And he sneezes, it was 2 hours, in the meantime he switched between CO and DHW (for washing id.) And finally he did not start again. "Error 6A" popped up.

I connected the uA (DC) meter in series and it does not measure anything, when set to AC it shows 5uA, but it's a shame because it should measure DC current. I can see a light through the window, so the glow electrode is working.

Will I buy such an electrode on the spot (what is the manufacturer's symbol, because they haven't even described it ...?) ??

It should measure AC current. 5uA is OK

Ionization electrode order no. 7100238 price catalog PLN 88.92 net

Check that the phase with zero has not been changed.

ABCEKO search, only the price higher than stated in the post above. Check the burner gasket, it may also need to be replaced.

OK, thanks for your help, I keep working.

It is clearly stated in the furnace maintenance manual that the sensor should be measured with a DC microammeter ...


By the way, info for people who have encountered this error at home. After talking to a specialist, a few observations:
- You have to check if the glow plug is on, because if not, then part. ionization will not detect a flame.
- Banal - but apparently there are a lot of cases - check if there is gas in the installation, there could be a break or the meter could freeze! Not everyone has gas appliances at home outside of the stove and this can be overlooked ...
- After cleaning the burner chamber, you need to pay attention to the chamber gasket (as the predecessor wrote) and sometimes a gasket from the gas pipe is made.

They really were. I have DC under AC voltage on the meter. Maybe that's where my mistake was.
If there is no ionization current, check the sequence phase, zero on the boiler power supply.
The question is whether the flame appears when you check the ionization.
Check what voltage goes to the glow electrode and what resistance it has.

As for the gas, I assume you checked and this one is

I like the effects, because I have the same.
Yesterday the stove reported a 3L error, I was afraid that the fan would help but cleaning the coil helped and yesterday the stove was working nicely. Today he fired 6A and does not want to start, the glow plug is OK, the chamber is clean, nothing is touched with the electrical system.

Is there gas? Do you have a gas stove? Does it work normally?

I have a stove with electricity, so I will not check if there is gas, but when I turned the valve on, something blows from the gas pipe. I have a stove for 8 years and there has never been a power outage, the neighbors also didn't say anything ....
Can you check it somehow ??
Today I connected a multimeter to the ionizing electrode in series, DCA setting, result 000. Pulling out the electrode, I found that there was some water in the torch cover. The electrode gasket fell apart in my hands. I dried it a bit and put it back together. It still does not work, but I do not see that the stove lights up at all - and should it be for a moment? (I looked at the eye after the light was turned off, only the electrode glowed and that's the end).

Is water in the inlet chamber to the burner normal? Maybe something got wet? Is the ionizing electrode damaged?

Your combustion chamber is dirty and the condensate drain is blocked.
Detailed service will solve the case.
greetings

Hi.
montertb and how did you deal with the defect?
I've had it for 3 years and nobody can fix it.
Boiler cleaned twice by 2 different service technicians, changed ionization electrode, all gaskets replaced, electrical connection checked.

The stove is burning what can be seen through the window and the ionization current is too low.

What I have noticed is that whenever this happens, you can see that it is fogged inside through the window in the boiler. If there is no steam, the boiler fires, if there is steam, then it is not.
When the stove stops for 2-3 hours and the steam comes out, it turns on again and works normally.

Hi!
I do not know about monterb, but for now I have peace. Thorough cleaning and drying helped, it stayed for a few days and fired properly, it has been flying for several weeks without any comments (of course, I replaced all the rotten gaskets).

Hello. I have a problem with the buderus stove. error 6A. I have a new gas igniter (magneto) but it does not work. I removed the control module and noticed that the glow ignitor is damaged. This looks like a thyristor or a triac. Replacing the entire tile is not profitable. I was given the cost of PLN 2,000.
Does anyone have a schematic of this module? Or knows what is this elment that turns on the glow ignitor? there is a relay on the way, but surely this thyristor or triac is damaged.
thank you for taking the time to read my post

The control panel costs PLN 890 net. So if you don't count, the 2000 is probably a bit too much.
