Vaillant Thermocompact VCW NL 182 E A 25 doesn't ignite

[Baaobaab]

Hello, please excuse me for writing in English, but my Dutch is still extremely poor.

In the house i'm living in Slotermeer I have this type of CV Ketel: Vaillant Thermocompact VCW NL 182 E A 25. Since last Thursday it doesn't ignite anymore - I mean it has gas and power, buttons work but there is no flame and so there is no heat and/or hot water.

I know is a old model, but currently there is no possibility to change with a new model, therefore please help me if someone knows / can fix this machine.

Thank you in advance.

Does ventilator start up?

When i connect it to the power and press the start button, it makes like a starting noise and then in the next like 3 seconds it starts another noise like a "buzz" - and this is how it remains stuck. Thank you

- step1: turn the black knob to position 8/9
- restart the central heater
- you say, after 3 seconds is stops making noise...lights
the red light up left next the 2 switches??
- Do you hear the fan? the position is almost on top of
the central heater

Sorry, it doesn't stop making noise, only after 2-3 seconds starts another noise also - might be that ventilator.

I turned to pos 8 (max), restarted the unit and makes the same, but no ignition. Also, the red light doesn't light

I also noticed that small glass round window on the upper part and i was thinking there i should be able to see the pilot light but i see nothing there

Staat de gaskraan wel open?
Mijn Engels is niet zo goed.

Scherp Kees, die staat inderdaad dicht.

Open the gas valve under the heater!!

Sorry, forgot it...

Anyway, i opened the kraan, i restarted all procedure and nothing happens, it is exactly like before. What i noticed now is that on the top, next to the exit of the exhaust pipe, it is a little bit warm, so i guess it is from the pilot light.

According to someone who came before, problem might be from that piece E43, the unit somehow it doesn't "know" anymore when to open the flame. But he is not sure, so he gave me this forum to ask more.

Thank you

I think the answer of Marcn88 is the right one.

Thank you, tomorrow I open the cover and check, but any specialist willing to fix it is welcome, I think is more safe.

 

[Wilibald]

The correct answer, search a specialist to fix this, but not on this forum
