Are you seeing an F75 fault code in your Vaillant boiler?
In this video Tony Hernandez of Advanced Heating & Plumbing explains what to do when your Vaillant boiler stops working and is showing an F75 fault code.
F75 fault code is usually an indication that there’s inadequate pressure in your boiler. The system should start working again when you repressurise and reset the boiler, so watch the video to see how that’s done.

My boiler turns on, then after a short while straight back to f7.5. Sometimes it works after the reset but more often it doesn’t and we need to keep resetting it. Any ideas?
Thank you, unfortunately I only watched this after having a cold shower 😂
Thanks. My Vaillant has issues every few years despite being serviced regularly. Had similar outages in a previous house with a Vaillant, bad reliability or are all boiler brands the same? Pump issues, losing pressure, PCB issues, etc.
Wow Tony – brilliant post. Thank you so much👍🏾👍🏾👍🏾🔥🔥
😮worked. Thanks
Just had this F.75 code. My pressure was low. Thank you for the fantastic advice. Followed the Video and all sorted now
Thank you just fixed my boiler.
Thanks, dude!
thank you so much this really helped and saved us a call out fee Thank you 🙂
Great video mate helped us right out!
Thanks Tony! Sorted my boiler in 5 seconds 🙂
Wow! Thanks so much. Partners away and I have hot water again! Super Star!!
Thanks so much as this happened to literally just now so extremely grateful
thank you so much
Thank you so much, got me sorted on my Glowworm Energy 25s! ❤
Saving lives during the winter 🤞 thank you
How do I adjust the pressure of the boiler? Mine is reading 0.8 but the +/- buttons do not seem to control this. Cheers
Thanks so much, worked a treat
Can you get an F75 with too much pressure?
Have no choice but to call an engineer out as my boiler is not filling up and the pressure gauge is low. It's also leaking water for some reason.
I would like to thank you for helping me fix my boiler. It’s a Saturday and upon working up I realize the boiler’s red light is on and the water is not getting hot.
I panicked and went online to see what the F.75 was.
I came across your clip and fellow the instructions safe to say it worked first time so THANK YOU SIR
Is there a way to do this if the boiler doesnt have the valves underneath it?
Thanks so much for posting this video. Vaillant codes can be a bit daunting to the uninitiated, so it was great to find there was a very simple solution to my problem. I'd have been really cross if I'd had to call out an engineer for something so straightforward!
Amazing instructions – all fixed with your guidance over the Christmas period 🎉
Thank you 🙏🙏🙏
It’s still not working 😢
Saved me a call out. Thanks very much!
Excuse me I have the ecoblock plus and I don't find the button of the wather. Please help me
Legend, mate. Saved my life on the coldest night of the year. I owe you a pint.
Tried repressurising the system, boiler starts for a minute or so, then back to F75, when the boiler starts the pressure looks fine.
I have a f75 fault that only happens when I switch the heating on, hot water works fine. Any help please
THANK YOU 😁
I had an F75 code. I turned the taps to refill and my boiler's gone dark. No power getting to it so can't reset it
I have an Echotech plus that has been doing the F.75 thing and going down to zero pressure a lot after being off all spring and summer. Different boiler, but these tips worked and I have hot water again. Thank you, you're a gent.
You’re a legend tony
Thank you so much – you are a life saver. ❤
Thank you for this, I've just fixed my boiler

Brilliant, and straightforward, instructions. Thank you!
Brilliant. Problem solved.
Spot on. Thanks
