Thanks again Roy and Allen, for making it as simple as black and white.

This video helped me to understand why my 10year old Potterton Gold HE was banging sometimes. It was when radiator valves closed at certain temperatures. Ordered the motor head using the correct part number but the non- spring loaded type was supplied-This was the source of the problem. Sorted now, thanks for the free advice.

Roy you are a legend , a fountain of knowledge 👍

[@emzdarlington9661]

Seriously very helpful video guys, can thank u guys enough for the high effort goes in these videos

[@AllenHart999]

Thank you very much for watching

[@rayc1503]

Fantastic Al & Roy, & thanks to viva for making this possible. You're both extremely knowledgable engineers 👍.

[@iheggis86]

Another great video thanks Roy & Allen

[@paulnixon4489]

The worlds our Royster. 👍

[@AllenHart999]

Thank You

[@zeeshannajib1787]

Very well explained, you made it simple and easy to understand

[@bahiaharjinder]

Hi allen thanks for another super sunday video, hydro block on a baxi combi instant would be awesome Thankyou roy + viva

[@moulesanctuary]

Brilliant classroom stuff .. Ive learned alot .. I am on my way to change a divertor and the motor this morning

[@sheriefgerges7789]

Great Video, what is the part no of spigot for the pump and brass washer for thermistor Thanks alot

[@Hannah-yz6in]

Can’t believe this video is only 11 months old- thought it must have been from years back with the way you’re describing people as blokes who can’t read instructions etc. I love your content and find it so helpful but the world is changing and it’d be good to see you be more mindful of all the women who work in this industry. And not all the men who do this job are just ‘blokes who don’t read instructions’! Come on Allen and Roy- you’re better than that!!

[@brendanconnolly8341]

Excellent as always

[@tonywardell3411]

Brilliant video thanks lads

[@user-bl4ed7cx5p]

Just a question, what is the resting position of the diverter valve on the Baxi duo tec?

[@mikecave4154]

Top video lads 👍

[@abualam4418]

🙏 thank you. Appreciate your work

[@kalsingh3660]

Hi Allen, thank you for this detailed video. Really helped me out! Many of these motors look fairly universal, not sure if you know but would this motor fit a Ariston HE series boiler? They all look extremely similar.

[@arronblythe8086]

Cracking little Video 👌

[@baffoxxx2117]

Hello, my question is the following: When the boiler is off, where is the three-way valve positioned towards the heating systems or the sanitary water? Thanks

[@BELHORIZON31]

Hi, i got an issue with no hot water, can i just remove the cartridge from the diverter clean it and the. Cross the finger?

[@ChrisA-z2q]

Hi - I've a Baxi Duo-Tec Combi 24 HE. I have an issue that the heating won't come on unless the hot tap is switched on then off first. Would this be linked to a faulty diverter valve?

[@GasTraining]

Did you find the answer to this mate? Got the exact same issue but can’t figure it out

[@neil5628]

Does the light flash red on the right side diverter valve when its not giving hot water??

[@sheriefgerges7789]

Hi Allen when I write the part no to find flow switch turbine type can't find all bobbing type can you please put link for turbine type to buy one Thank you

[@suheilhanna873]

Great one, would you please zoom in, to see the part clearly, appreciate your hard work. 🙏

[@oscaribarramartinez1033]

Fantastic

[@AllenHart999]

Thank you so much 😀

[@rayc1503]

Roy/Allen could I just ask the effects on water flow rates. Lets say if I were to put a larger or smaller plate to plate on a boiler. How would the boiler behave? I've never tried it myself, I'm just curious that's all, thanks 😉.

[@daviddavues1677]

Legends

[@huunghiem]

Hi Allen I got Baxi 28E it that mean if my boiler are on then I turn my hot tap on the diverter stop run hot to my radiator? I just noticed the light on the boiler turn over to the hot tap if I run the hot tap.or you should see both light on(hot tap and the radiator light on)? Thank

[@royfugler9971]

Hi Yo, Yes when you turn a tap on the diverter moves to hot water and shuts off the central heating, once you turn the tap off if there is still a demand for central heating the diverter valve will move back over. With a combi you can only have hot water or heating on at one time not both together, that is why the radiator light goes off when you run the tap.

[@royfugler9971]

Sorry Ho, I spelt you name wrong

[@davidb2464]

Again, great video Roy. I may have missed it, but let's say that the hall-effect sensor is faulty/blocked, what might the symptoms be? Would you suggest giving things like these a quick rinse on a service every couple of years?

[@royfugler9971]

Hi David, Thanks for the feedback. If the hall effects sensor is blocked, the red led wouldn't light up. Hopefully soon we will do a video on a live boiler and I'll demonstrate what would happen and how to test it.

[@davidb2464]

@@royfugler9971 Hi Roy, thanks for a great answer, looking forward to the video of this. Keep up the good work.

[@richardnixon8410]

Roy, my 105 instant diverter valve is letting by in CH and pre heat mode, I overhauled the valve with a kit , but still lets by, any ideas pls, I descaled the Plate h/e and top up expansion vessel.

[@royfugler9971]

Hi Richard. Check the by-pass valve in the rear of the right hand hydroblock, it could have dirt on the seat.

[@user-pl7oo6dc3j]

Hi, after gas safety engineer left the water wasn’t heating he came back and fiddled with some pipes under the boiler and then we had hot water. This happened twice! This year the radiators don’t heat up! They were ok until April and the safety engineer came in August… now it turns in for around 10-15 seconds and the boiler flame light turns off! I wonder if this time he has stopped s valve or something connected to the radiators? I’m a little suspicious that he charges the landlord every time he visits our flat. Please help!

[@veronicahart450]

Good video

[@strider0106]

you forgot to give us the part numbers

[@timeyre9985]

when all else fails read the instructions

[@derekclark7545]

Can you do a Vaillant hydro block, well you did say anything. hahaha.

[@terryquinlan5901]

My boiler is pressurising itselve,I have changed the pressure or expansion vessel and the divert or valve cartridge also cleaned and flushed out the plate exchanger ,the pressure vessel is pumped up to 1 bar with air but the pressure still rises to 3bar and continually releases to via the external pipe. I have also removed the filling loop on the boiler and capped off pleased help before I go mad what do you thing is causing my problem Terry
