    I have a WHBC 28/33 C. The same error is displayed to me. After the reset it is ok but for a short time. Can I have a hint what might be wrong. It is over a year old, which is not so old, but this situation pisses me off. The service technician is not eager to repair. greetings

    Since one year is probably under warranty, it is better to wait for a service technician

    This error says that the boiler had a problem with starting, to be exact, it did not see a flame.
    There can be a multitude of problems, but these are quick:
    1. Incorrect phase polarity in the connecting cable - whether the plug was accidentally inserted. The phase must be on the brown wire in the boiler, provided that no one is messing around - check it
    2. Problem with the outflow of the condensate - check the condensate hose to see if you have siphoned extra somewhere
    3. Check the siphon in the boiler
    4. The ionization electrode likes to deform - check if it looks like in the documentation - it is very well described.
    5, Chimney ...
    6. Dirty exchanger, but after a year of operation it is rather hard to get clogged up

    I bet 1,2 or 4

    Hello. I have a WBS 22C oven. He worked without any charges for 13 years. The problems began after the annual service: exchanger cleaning, adjustment. Every now and then, when the stove was going to "high speed", errors appeared: 151-ext. BMU, Diagnostic Code SW 276 - Pos. reg. burner for interlock 12, indication of reg. burner 99. After errors, a reset was necessary from the switch on the stove and the stove worked again for some time.
    The C209 capacitor had a capacity of 44 nF, after its replacement with a new furnace, it works without interruption for the time being. Hopefully the cause of the problems has been fixed.
    I am asking for a hint, is it necessary to re-adjust the furnace after replacing this capacitor?
    I checked that during the operation of the furnace, in the specialist menu under the ionization current item, the value is about 15 uA and it varies from 14 to 20 depending on the flame.

    You do not have to adjust the boiler, changing this element does not affect the gas settings.

    Remember, however, that you were ignoring the boiler safety circuits.
    this element is responsible for opening the gas valve, you are not sure if you have damaged anything else on the plate or if it was damaged.

    Hello, after replacing the capacitor, and putting the board in its place, the boiler works ok, but at the very beginning for 1 minute an error appeared, but after another reset it clicked and works normally, replacing the capacitor with a slightly different but with the same parameters 150nF 250V MKT SIEMENS Capacitor

    I warmly welcome.

    I am asking for an assessment if my diagnosis may be correct.
    WBS 22 C oven, started 10 years ago.
    A good two years ago I was cleaning the exchanger with taking out and rinsing.
    Last heating and summer season OK. Now the problem is growing rapidly
    Error 133 (no flame) and winter is just around the corner. Error only during ignition.
    At the same time, when it works only in the CO mode at low temperatures of about 35 degrees and low revs, it works well. Without any problems, after extinguishing, it lights up again and continues to heat the central heating.
    As soon as I turn on the hot water and the stove increases the temperature e.g. to 65 degrees Celsius. it warms as long as it is
    exceeds the temperature and shuts off according to the procedure.
    At this point, it does not want to fire anymore, despite the gas igniting with an equal flame on the burner, error 133 occurs and the blockage after a few attempts.
    Reset doesn't help. Recently from 3pm on Sunday to Monday and at 9am
    he just lit it.
    I also noticed that after unsuccessful ignition attempts in the furnace MENU
    (heat source diag.) despite the appearance of a flame on the burner,
    the ionization current is not 0.

    On Friday, the service technician replaced the electrode block as if he had set everything up and even
    the stove caught fire. Unfortunately, when I got home in the evening, the stove was already blocked (133) and it is the same.

    The question is, could it be this unfortunate capacitor?
    I watched the record and there is just such a blue one (pos.209), though this one
    has different markings in advance (in the photos) than those in your photos.

    Thank you in advance for a hint, a hint or an assessment of the situation.
    Because I don't know if I can count on a service technician

    greetings

    Yes, this capacitor at the transformer is responsible for measuring the ionization current.
    The current is best compared in the diagnosis menu as you wrote with the real current on the meter

    I warmly welcome,

    Thanks for your confirmation.
    Today I bought a capacitor in the store, it looks different, but apparently
    parameters and operation will be the same.
    Can you confirm that it is suitable?
    I post a photo



    Thank you and
    greetings

    Hello,

    I measured the ionization current.

    During ignition and appearance of flame before the regulator cuts off the gas.
    For each of the many attempts, the meter shows a current of about 16uA per
    display in the oven zero uA.

    After a long time and even a dozen or so resets, the stove unexpectedly ignites and
    works normally.
    On the meter, depending on the speed and power, it is from 8 to 18uA.
    Similarly on the stove, but about 1uA less.
    So the ionization electrode works.

    I think that for the sake of peace of mind, I will first clean the exchanger with chemicals,
    then I will replace the capacitor. I hope there will be an effect.

    I have a question if the ionization current is of the right size

    greetings

    Do you realize that such independent interference with the boiler's main plate will result in failure to pay compensation or with a prosecutor?

    One year after replacing the capacitor, the problem returned. After it was desoldered, it turned out that its capacity is 40nF - a year ago, before soldering, it was about 150. After installing a new 150 nF, the stove works properly for 3 days. The previous one lasted 13 years, and this one only a year ...

    I will repeat the question. Are you unaware of the consequences of your messing around with the automation board? In the event of a possible fire caused by the boiler and the detection of interference with the automation, the matter will be completed without any compensation, because the interference will be considered the cause (a similar situation as on the road where the one who drove someone back is always to blame). If something happens to someone because of this, they may end up in jail. On the other hand, if your own safety is worth less than 3 zlotys for a repair kit, that's cool. Any advice that encourages to dig around in boiler automatics should be removed ex officio in my opinion.

    Hello.
    I have a similar problem. Boiler Brotje and error 133.
    I hear a spark, but the boiler won't fire. Error 133 pops up after a few tries.
    I checked the motherboard and there is a capacitor, but it is gray in color. I wonder if I should try to replace it.
    I am asking for help and suggestions. Winter outside and the stove does not work.

    What should I do if this error pops up after connecting the furnace (WHBC 22/24) to a constant-phase sinusPRO E (700/1000) UPS?

    Welcome to the thread.

    I have a WBS 22E boiler, 10 years old. A similar problem happened to me. Namely, at start-up, the spark gives a flame for about 5 seconds, then goes out and error 133 pops up. The furnace tries to start several times until it finally gives up and only manually resetting the error causes another start-up attempt. In 2-3 times of manual reset, the boiler starts up. I bought an exchanger cleaning fluid, it was cleaned two years ago. I downloaded the maintenance manual and intend to do so in the coming days.

    I have a question, is there a capacitor on my board that needs to be replaced? From the posts above mine, I can see that the board is different and the description of the capacitor on the board is also different. Second thing, should the electrodes also need to be replaced after such a period of operation (heating DHW)?

    And cleaned comprehensively, in accordance with the service instructions. I sprayed generously with the satin liquid, I recommend to protect the back wall with, for example, a thick foil. After undressing, there was a bit of this raid, cleaned with a liquid and a soft brush.

    The boiler starts every time.

    It's been a year with a wrap of good work. By the way, a year ago at cleaning I replaced the electrodes, plus gaskets.

    Today a new problem by surprise, the disappearance of the flame, error 128. In the instructions nothing is written what this may be the cause, what to check.

    When starting the flame is as if weak, the fan first slows down, enters as if in a lower vibration and the flame goes out. Alternatively, when it doesn't go out and the fan starts to increase the revs then I have the impression that the mixture extinguishes the flame, as if there is not enough gas in the mixture.

    What I could do I did, that is, I cleaned the exchanger, it was not particularly dirty, I screwed it up and the problem remains. The furnace does not go into operation in any mode, neither CH nor DHW. Unstable flame burns about 15 sec.

    Has anyone any idea before I call service? It is known winter:) .

    Hello

    A question maybe someone is able to help because currently the service technician is very busy and can be at my place in a week at the earliest and I have been struggling with the problem for about 2-3 weeks now.

    Boiler BROTJE WHBS 22 D 22 year
    Error: e133 pops up from time to time, there is no rule, once it works all day the worst is at night it can switch off and in the morning the whole floor gets cold.

    With the help of a service technician I cleaned the electrodes, then replaced them with other used ones but the problem persists.

    I live in Silesia, Tarnowskie Góry

    Yesterday I was fighting error 133 and it turned out that the condensate drain was clogged, after I opened the chimney you could hear water bubbling when the fan started. A plug had formed in the tank above the siphon and was flooding the air supply, once the deposits were removed everything was fine👍.

Topic summary

The Broetje WBS2 22 boiler frequently displays error E133, indicating "no flame during safety time," typically caused by ignition failure or insufficient ionization current. Common diagnostic steps include checking electrode positioning, ionization current values, and phase polarity. A recurring hardware fault involves a defective capacitor located at position C209 on the control board, often with a nominal value of 150nF and voltage ratings around 250V. Replacing this capacitor has resolved the error for many users, restoring proper flame detection and boiler operation. However, some newer boards have addressed this capacitor issue, shifting focus to other causes such as dirty heat exchangers that restrict airflow, leading to flame failure during modulation at lower fan speeds. Thorough cleaning of the exchanger, sometimes requiring disassembly and chemical treatment, is recommended to ensure adequate air supply. Additional troubleshooting includes verifying condensate drainage and siphon integrity, as blockages can cause air supply issues and flame loss. Electrode wear and gasket condition also impact ignition reliability. Users report that improper DIY repairs on the control board may void warranties and pose safety risks. Professional servicing is advised for capacitor replacement and exchanger cleaning. The error may also be influenced by boiler operating modes, with failures more common during hot water demand or modulation phases. Ionization current measurements around 14-20 µA are typical during normal operation. The discussion includes references to related models such as WBS 22C, WBS 22E, WHBC 28/33 C, and WHBS 22 D, with similar error patterns and solutions. Overall, resolving error 133 involves capacitor replacement, exchanger cleaning, electrode inspection, and ensuring proper electrical and condensate system conditions.
