- I will show you how I go about replacing a pressure sensor in a Vaillant or Glow-Worm boiler because the sensor has become stuck or is misreading and your getting F75 in your display.
Also what F73 means and why Vaillant moved the pressure sensor from the bottom of the boiler to
the middle of the boiler and have kept this position on all new boilers. I show you how to move the pressure sensor to this better position.
I really appreciate your support and a cup of coffee goes along way. Helping me to make more videos to help you.

Thank you so much for the video is very good
Thank you Mark!
Many thanks Mark for the info, I did have an issue though because the connector on my new original Vailliant 0020059717 sensor was different from the original on my ecotech plus 837, and I ended up cleaning the old one out and refitted that, which fixed the problem for now.
Thank you
Great video
Vielen Dank!
thank you
Mark my combi boiler is at the highest point above rads in upstairs cupboard .
Can I not close the flow and return valve and just drain boiler , only I'm not wanting them isolation valves to leak and hearing that there prone to leaking is making me nervous about doing the job great video mate thanks for your help
Thank you, I can’t see how I can add water pressure though,.. I’m only showing 1 bar
I presume the diverter valve is turned to hot water mode before the boiler is turned off but How is the air lock on the heating system created ??
How do you know if its the sensor or the pump at fault ? Do you have to change the sensor first and see ?
Hi Mark, I successfully changed the vailliant water pressure sensor, after it displayed a F75 fault. Found a lot of debris on the old sensor. But since then, the pressure keeps falling in the boiler. Check the property throughly, and have found no leaks in the system. Its a heat only boiler attached to a mega flow system, with underfloor heating but no radiators on the system. Any ideas as to the reason for this pressure loss??
Sensor at high level with boiler drained alite more tricky get a small container to catch 2 litres of water when removing sensor
Can Turkish be included in the language option list?
Don't you have to run the air purge function afterwards?
My pressure sensor connector is corroded. Presumably it got wet when the boiler was serviced. Any idea where I can find a replacement connector?
First 👍👍👍👍👍
