Thank you. Watching your video has saved me a lot of money and time. I bought a new motor for 15quid and it was fixed. Happy days. Thank you :))))

Thanks! My motor was fine, but the mechanical valve was frozen. A simple wiggle with pliers and it was free!

Thanks. My heating was stuck on open. Replaced a danfoss motorised valve unit and it's working fine.

Excellent - thanks for this - I think one of ours has ceased but now know much more about how it works.

Much appreciate for sharing the videos, great help to understand the problem, Actually by turning on hot water, it was triggering the heating of radiators, But by watching your videos i understood that what was the actual problem. Thank you so much.

A splendid effort! 👌🏻

Thank You for this vid. Im off to buy the motor now

Brill video clip! I changed the motor on mine about 5 years ago. Occasionally now, after the heating has been off all summer, the mechanical part of the valve sticks.. but all I do is unclip the top, and with a small adjustable spanner, gently work the valve pedestal either way. Its never very tight and only has ever taken a couple of minutes to sort...and its not every year

Thank you - I am warm again!

Wow what a guy. Think I have this problem will try tomorrow when light and can switch off power.

Very helpful information thanks

Very useful! I've just dismantled the valve and found the posts holding the return springs had both broken (motor is fine). (Dead giveaway when I dismounted the actuator and there were multiple rattles from inside!). Hooked the spring ends into the holes where the posts used to be and the valve now seems to be working properly. Thanks for the view of the internal workings!!

Great info, I didn't know Screwfix sold motor replacements.

Many thanks fantastic video

Thank you for that. Have replaced my motor as the actuator was becoming unreliable (valve itself moves freely by hand). Took 5 minutes to do - gently prised off the connectors with a small screwdriver. My actuator was replaced 2-3 years ago .. disappointing as the previous one had lasted 12+ years!

Thanks for this! I was looking for a video on how the Drayton MA1 works, but this gives me enough info for what I need. I am finding that the actuator moves as expected when it is removed from the valve, but for some reason does not seem to be strong enough to turn the valve when attached. It could be the valve has become too stiff or the motor is no longer strong enough who knows. I have manually set the valve in the hot water only position, which should be good until winter comes again

Brilliant thanks 😊 👍

lovely little vid, same happened for me.

Great job thank you

Thanks for this video. I have had problems with my heating working intermittently for the last few months. It will work fine for a few days or maybe a week and then the boiler won’t fire when the call for heat is made. If I turn it all off for a couple of days and then start again it will work again for a while. I assumed it was the boiler at fault nd maybe the PCB but then I noticed the hot water on its own works fine, boiler fires no problem and it works as it should. It only seems to be when CH only is selected. I can hear the boiler clicking on and off trying to start so I think it communicates with the room stat, goes to start and then the mid position actuator doesn’t move as it should. Does this sound the likely issue to you because if it was the brass valve then the hot water wouldn’t work either? Thanks.

Thanks for that Having this issue with switch stuck on open and rads always hot. Will try to take it off and see if I can manually close it. These things always happen on week ends when no electricians around :(

Thank you :)

That black lever on mine will not budge at all. It's stuck in the groove. Should I replace it? Edit: You can manually move it to the heating position, you can't move it back. Mine turned out to be the valve sticking, I removed the actuator and then manually moved the valve with adjustable spanner which freed it up, now it's possible to move it with my fingers.

Thank you for this video. My mid position valve is playing up, so it is hit or miss if the heating is coming on. Also, the arm to select water, heating or both has fallen inside, so I feel it would be better to replace the whole box rather than just the motor. From experience, would it be easier to remove the black mains lead from the valve end or from the wiring panel?

Can I ask the activator/value stop working so I tried to take off and realised it did have a screw securing it, but then decided to leave it but on try to lift off, it's actually freed it up and now working thou on everything depending if i have put heating on or water. But the activator is now physically the white box from side to side slowly when changing to different heat or water, is this right??? I guessing not but just checking, at least i have heating now but wanted to know if safe please????

Nice

Im is this everything works well valve just is warm all the time, is it supposed to be like that ?

My actuator changes position from heating to hot water no problem, but recently we noticed that whn we turn on the hot water the heating is on as well, while the actuator is on W position [meaing hot water only no heating]. I cant figure out why my radiators get hot :(

4:14 Which button?

Could a stuck valve cause the electricity to cut when heating/water is switched on? The valve was warm even when the system was off?

How do u know/ check it's the motor not the 3 way valve ?

Can this three point valve cause be my problem? I have a combi boiler and some of my radiators get hot during the night!

One of my springs had failed as the plastic mounting stump had vanished, spring secured with cable ties and heating works again. cheap fix.

Thank you mine is stuck on heating and hot water £20 for the motor

It's not as easy as this guy makes out. To get the bolts back in you gotta line up a hole in the plastic moulding of the valve with a hole in a loose metal base plate with a hole in a seperate metal heat sink with a hole in the motor casing. For 2 bolts at the same time. Now screw in the bolts with one of your other free hands. Good luck with that. Helps to have 6-8 hands. Or tentacles.

You blinder!

What's the difference between a shoe valve and paddle valve? Are they interchangeable? Is one better?

What makes this actuator valve hum loudly please?
