Viessmann Boilers Guide

My Viessmann Vitoplex 200 boiler keeps cutting down constantly. The Viessmann boiler works well for a few minutes but afterward, I have to face this problem again. I have restarted the boiler in order to make it work again but no success. What is the matter?

Please guide me

Josh

Hi Josh, there are several potential causes behind this problem like the air trapped in the boiler’s radiators, frozen & chocked condensate pipes and damaged thermostat. Nevertheless, the highly common & disturbing reason is the damaged circulation pump. The basic purpose of a circulation pump is to give a balanced amount of a hot water. Once it fails to work then, the hot water stays in your boiler. Therefore, because of this, the boiler keeps cutting down recurrently. Well, it is better to call an expert Viessmann Boiler engineer for systematic inspection.

Hi Folks,

I urgently need your help regarding an issue with my four years old Viessmann 200 boiler. The burner of my Viessmann 200 boiler is trying hard to spark promptly at ignition mostly for 15-20 seconds however, haplessly the burner has no ignition. What you people suggest, as it is quite difficult for me to withstand with this problem.

Please share your views

Hello Rita, this issue is extremely common in Viessmann 200 boilers. For overcoming the problem, try to consider the below-mentioned information:

1. Check the electrode & ignition lead of the boiler. It is best to replace them if you feel so
2. Examine the different electrode connections. Fix them if required
3. Test & repair the position and the spark gas
4. You have to fix the different connections which are positioned at the printed circuit board and ignition producer
5. Lastly, check for the jammed shaft and fix it

Do call a trained boiler engineer if your problem persists

Hello Everyone,

My one year old is not proving me with the gas whenever I try to use it. I am facing this problem from last few days. What is wrong with the boiler? Guide me please

Anxiously waiting for the expert help and advice

Thanks

Janice

Hi Janice,

I guess the gas controller of your Viessmann Vitodens 100 boiler is faulty. Its basic purpose is to check & control the needed gas flow, which is going towards the burner & pilot light of the Viessmann boiler. At times, the gas controller became damaged & due to this, it failed to perform properly. Some other reasons behind this issue are as follows:

1. Faulty PCB
2. Damaged unit
3. Issues with the connections and wirings

I would advise calling a proficient boiler engineer for detailed investigation.

Hi Guys,

The Viessmann Vitoplex 200, which is almost three years old, is not firing up since last night. What should I do as the boiler stopped working due to this problem? Please help

Regards

John

Hi John, if the problem with your Viessmann Vitoplex 200 relates to the unit, which will not catch fire then, there are some potential reasons. According to the Viessmann, this is the problem with the boiler’s burner. When it is blocked due to debris then, it is sufficient to cause a fault. Nevertheless, it is possible that there is a problem related to an air pressure-measuring device. You can fix it by doing the following things:

• You have to inspect and clean the burner
• After doing so, check the air pressure-measuring device.

This sensor tells your boiler that the air pressure is under a safe working range. In case, there is a problem with the PCB, wiring and sensor it interconnects with, it will not ignite. Thus, the outcome could mean the PCB replacement, new sensor & repairing the wiring.

Hello Everybody,

My seven years old Viessmann Vitodens 100 is continuously displaying an E3 error code. I have tried to find out the hidden meaning behind this error code after reading the user manual but did not get it. Someone please me to sort out this problem.

Your suggestions will be highly appreciated

Thanks a lot

Gabriel

Hi Gabriel, an E3 error code on your Viessmann Vitodens 100W boiler deals with the “wrong adjustment of a combustion controller”. For rectifying the problem, you have to follow the below given steps:

• Firstly, ensure sufficient heat transfer & press a reset button
• Secondly, verify the current gap between burner gauze & ionization electrode assembly
• Afterward, verify the distribution of the gas type  
• Finally, verify the ventilation shaft system & remedy the recirculation of the flue gas if needed

Hi Folks,

I have installed a Viessmann 200 boiler one year ago. It was working well but now I have noticed that my boiler starts behaving weirdly as I turn it on. It also turns itself off like after every ten minutes. My boiler is under warranty should I contact a service center?

Thanks in advance

Bob

Bob, 

According to the above-shared information, your boiler is facing a problem of overheating. I must say that you should take it seriously. Well always be cautious and never try to investigate the problem at home because the boiler, which overheats a lot, becomes extremely unsafe. Moreover, your Viessmann boiler overheats repeatedly therefore; you have to turn off the electricity supply of your home. Once the boiler’s few important internal components, undergo extreme pressure it always overheats. Thus, try to inspect the problem immediately & in detail but with the help of a skilled boiler engineer.

Hello Everyone,

Someone please help me regarding an issue with my six years old Viessmann Vitodens 200 boiler. The problem is quite strange as the boiler is not offering the hot water and heating for last two days. I have tried to fix the problem after restarting the boiler several times but I think I am not doing it in the right way. Please help me to find out the exact reason

Waiting for your valuable suggestions

Bill

Hi Bill, here the main issue, which your Viessmann Vitodens 200 is facing, is related to circulation. Generally, a circulation error on the Viessmann Vitodens 200 boiler is just because of a poorly working pump. Besides this, two main reasons are always there when the pump fails to work properly such as a pump, which is installed by unexperienced boiler engineer & seized pump tube. It is better to call an experienced boiler engineer.

Hi,

My one-year-old Viessmann Vitoplex 200 is not responding properly from the last two days. I am trying to fix the boiler after examining the various important connections and parts of the Viessmann Vitoplex 200 boiler but unfortunately no success. What should I do to make the work again?

Thank you so much for your help

Jen

Hi Jen, you should take this matter seriously as sometimes a boiler who does not respond properly become dangerous. If this issue only originates directly from the boiler itself then, you have to check the current pressure of the boiler. If the boiler’s pressure is extremely low then, try increasing its pressure to a set level. Similarly, uncovered & badly installed condensate pipes frequently freeze in the extreme weather situations thus, causing your Viessmann boiler to respond weirdly.

Hello Folks,

I have bought the Viessmann Vitodens 100W boiler three years ago. My boiler is facing a problem of discontinuous heating. I am unable to fix this issue after too much hard work. I am getting the heat at weird timings like sometimes at 3 am & so. Has someone faced this problem if so, and then please share your suggestions.

Regards

James

Hi James,

The best and recommended solution is to contact a professional Viessmann boiler engineer, as he will replace the mechanical controller head. Beside this, it is advised to drain the Viessmann boiler carefully & replace the control device afore topping up your boiler. Sometimes, the replacement of synchronous motor located on the control device will serve the purpose.

Hi All,

I have installed a Viessmann boiler five years ago. I was happy with its performance as it worked well until last night. Now, I am having various issues regarding the boiler’s heating control. When the lights of the heating system and hot water are on for turning it on nothing happens. A few hours ago, I have noticed that the boiler worked well but, simply on the fixed settings. Nevertheless, now the Viessmann boiler has failed to work completely, as it should be, even when it comes to the fixed settings. What is wrong with the boiler? I am quite confused. Someone, please guide me. Should I get a new boiler?

Thanks for your help

Rob

Hi Rob, it is better to check the Viessmann boiler’s diverter controller thoroughly. Keep the boiler’s heating pump and Viessmann boiler together on the sole in order to investigate that either a diverter controller is supplying the required power to your boiler & heating pump or not. Moreover, it is recommended to call a skilled Viessmann boiler engineer for detailed investigation.
