VIESSMANN BOILER F4 FAULT CODE - How To Reset

[@kellyhanson4173]

Thanks Allen! It’s a cold December evening & the boiler came up with the F4 error message last night! Over the moon, followed your instructions this morning and I’m back in the land of warmth! Big thank you 😄

[@yungee3921]

Thanks ever so much for this very clear, very straightforward video. I fixed the F4 fault following your instructions so I have hot water again for now, but sounds like I need to get it serviced. It hasn't been touched for a few years at all I think. Cheers!

[@johnsharpe734]

Thanks Alan turning off/on cured it short time...but contacted the engineer....as you recommended

[@serekhomogenizowany3727]

Jesus Christ, my mum knocked the gas lever and we were wondering why after couple of resets it didn’t work. Thank you so much!

[@nobody7817]

(BTW--No idea what make or model this heater is--but your TS guide got me there!) New apartment (company provided), no hot water when I got here at midnight last night. I spent the morning trying to find the water heater...then found the F4. Looked at your video, 45 ish seconds in you say, "Gas repairman"... oh dandy...is there any gas on the stove, dummy? No? Ok I think I found the problem--they forgot to turn on the gas! Thank you so much!!!! (LOL I almost feel stupid, but then again, I thought all of these heater types were electric--I did not know they ran on gas...) EDIT: Found the gas main, turned it on, and all is happiness now! Thank you for the spot on troubleshooting guide!

Thank you for the video. Mine is an ordinary (non combi) Viessmann boiler fitted two years ago.. During the summer, I use an electric immersion heater for my water as I don't like the humming of the pump and don't particularly like gas, or water being pumped around. Just switched the boiler on (for heat and water) for the first time in 8 months and straight away got an F4 code. No idea what I was doing and noticed that the on-off switch wasn't pushed in .... It fixed the problem but have now come on youtube for some advice if it happens again.

[@hassmaster1]

I have this boiler and it’s showing F4 but have 0 pressure. Any ideas? Thanks.

A friends Boiler was showing the f4 fault code. His spark electrode was so bad it was warped. A new electrode fixed the issue.

Spark genny's are notoriously bad on these boilers , it's a design fault and viessman don't seem to have resolved the problem , I won't fit these anymore and I always recommend Baxi's to customers these days , cheers mate......👍

Done the reset, f4 error disappears for a while but flame icon never appears and f4 comes back. The gas meter guy came to do maintenance on the meter before his happening so it’s connected to that most likely

[@alexwood2219]

Decent thanks

Hello, do you know how to raise the water pressure?

[@dacelticcross]

had the f4 fault and it was just the propane ran out on one of the bottles,so i switched it...scared shit out of me lol.

[@metallitech]

I think this was the error code that we were seeing about a year ago (new boiler). Viesmann put in a new board and the problem went away.

...block internal condensate pipe can also result in the F4 code...

Thank you.

[@AllenHart999]

Thank You

[@laszlobauer5274]

Also check the if the gas sensor closed the gas shut off valve if you have that. It did not sound, and I did not have a leak, it just shut off because of the dust (the house is still under construction)

On peut traduire ça en français comment

[@johnfithian-franks8276]

Hi Allen, I am worried that if you show things that should be left to an engineer that people will try to do it themselves to save money, I am a hobbyist DIY'er and have built everything from underfloor heating to an entire house, but I will not touch gas because I don't trust it. My worry is that if someone has the same skill set as me but not the nagging "do not touch gas" thing they will try to save money because you have shown them how to sort a problem and that is a dangerous thing to do. By telling them it could just be needing a service or cleaned out they are going to think that they are capable to use a hover and clean it out without the safety of a registered gas engineer.

[@AllenHart999]

Hi John, Thank you for your comment, You make a very good point. Lots of manufacturers are doing these types of videos now, hopefully, my advice comes across to always use a gas engineer. Thanks.

[@joeeager4717]

Hi Allen. F4 fault. I have changed the electrodes,leads and pcb(as advised by viessmann) and still f4. No issue with gas 22mbar. Any idea?? Thanks.

[@zlac]

For me, it was "no gas"
