Thank you for sharing I left you half a pint for your help it's not a lot but if we all give him a drink he will soon be drunk😅 valiant pressure switch thank you
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.
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
For everyone's benefit. There are 2 tiny holes that the retaining clip needs to go back into. He doesn't really explain this in the video and trust me if it's not on correctly it will seriously ruin your day.
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??
Thank you, Sir. I like your clear step-by-step explanation!
Very good video Mark . Great explanations and description of what you're doing..

Thank you Mark..
Clear precise and today was a school day for me
Sensor replaced. 15 minutes. Thanks for the explanations!
Thank you so much from France Strasbourg 😊

How do you clean the gauze filter behind the sensor?

How do you know if its the sensor or the pump at fault ? Do you have to change the sensor first and see ?
VAILLANT VU INT I 306/5-ecoTEC Plus. Are there Two sensors or just one.Thanks

Sounds silly but could the coil be split inside the cylinder bud?
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?
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 deal with f20 code
Thank you, I can’t see how I can add water pressure though,.. I’m only showing 1 bar
Can Turkish be included in the language option list?
First 👍👍👍👍👍
Sensor at high level with boiler drained alite more tricky get a small container to catch 2 litres of water when removing sensor
Hello,how do You know is fault on Lower or upper sensor ?
thank you
