Those error codes appear when the heating is on, but they affect the use of domestic hot water. As configured by the factory, the boiler will shut down if it has trouble igniting the flame within a 20-minute period. This happens when someone turns on the hot water from the tap for 1-2 seconds, not giving the boiler enough time to ignite the flame. This is counted as a missed ignition. This feature can be disabled in the settings.
Hi, Mark Thanks for the info. I have a question. I have Vaillant Ecotec Plus system boiler plus unvented cylinder. When the boiler is on, the radiator is working but there is no hot water. I have tried the DHW (domestic hot water) setting on and off seperately, but still no hot water. Wondering what go wrong, thanks
Hello I keep having code f35 on my valiant ecotec plus vented. I checked all the vent piping and there are no blockages. After resetting the code returns after 4-5 days. Thanks
Would be great to see video of other Vaillant eBus controls such as the wiring centre for S Plan and Senso home thermostats, no one has put any up for some strange reason
Hi Mark, Great very instructive video. I really enjoyed it. Small question. Can one use a timer function on the “home domestic water comfort function” (eg. from 07 am to 07 PM and then off) or do you have to change it manually in the app? Looking forward to your new videos.
Hi Mark having installed a couple of the new 625 models we have had problems with them stuck on low flame so will only reach around 53c if we reset it will go to full flame and the next day it reverts back to low flame any idea's Regards Richard
Hello Mark, Can I replace my old VRC470/4 controller with a newer controller? Do they all work with 24V ? Do I need an adapter plug for the newer controller? I have a VWL 85/2 A heating/cooling system. Thanks.
Hi Mark, great video - thanks. I also bougt an ecoTec Plus a few weeks ago and when testing some things i put it into summer mode by pressing the heater button 3 seconds. My problem is that i use a Tado smart controller on the eBus instead of a Vaillant controller - Tado can not end the summer mode - will resetting the boiler to factory settings and configure it new based on the diagnostic infos end the summer mode on the boiler? And is there any risk when resetting to factory settings?
Weird things happening with out install (occurring as I type this) there is no option to set whether the boiler is using weather compensation, and under the diagnostic codes there is no option for 162, there is just 161 and 164. Tried a factory reset and nothing.
Mam poważne problemy z l.16 Płomień gaśnie przy mocy minimalnej. Kilka, kilkanaście razy dziennie, póżniej kilka dni spokój i znów wraca. W Polsce nie można znaleźć żadnej pomocy z tym problemem. Może Pan pomoże.
hello mister greetings from turkey i'm getting a vaillant ecotec plus f105 malfunction.could you please share information to solve the problem. thank you.have a nice day.
They made an easy menu from past models into a tedious and long winded annoying one! Best keep the installer number hidden. Customers love to play around with boiler settings then claim they didn't touch it.
Thank you for this, I couldn't figure out where the reset button was after I had my gas meter changed. Much appreiciated!
Great information Mark also tidy installation thanks it helps

With regards to filling, if you power up before filling it will enter purge mode whilst filling to clear air from the heat exchanger via the AAV. 👍🏻
Please help me I have a very simple control unit and my boiler won't heat the house up simply wont go over 18c⁰
Get an engineer to assess the job, you probably need a new control.

Would you recommend this boiler?. I have the old 831 that needs replacing.
Comfort mode is for heat or hot tap water?
Would be great to see video of other Vaillant eBus controls such as the wiring centre for S Plan and Senso home thermostats, no one has put any up for some strange reason
Vaillant have some good tutorial videos for engineers, on their Advanced e-learning portal, which covers this
Thank you Mark

Radiator mode has dash across it meaning it's off - how do you get it on ?
Great video Mark! I get all installs are different, but what kind of cost should people expect for installing this particular boiler?
Is it the same price as its predecessor?
Hi Mark, what is the fault code F.105 about please? It reads "Gas valve offset incorrectly set"
Please help 😬
Thanks very good perfect

How do you undo the test point in the gas valve
Alan key.
this one or the eco tech pure 830 ?

Hi, where can I find enter access code ? Thanks
What is the access code
I did some research and I think that number that was censored is 17
The code is 17
Did they just take the sensoComfort and integrate in into the boiler?
Sorry cant answered that as I've never liked the Vaillant controls so I've never used them before now
F57 eroare?
F57?
That code should be secret only for engineers to know
It's in the manual, everyone has access to it if they can read.
They made an easy menu from past models into a tedious and long winded annoying one!
Best keep the installer number hidden. Customers love to play around with boiler settings then claim they didn't touch it.
I wont be walking my customers through that menu. Totally Agree. I've seen other videos showing the code, that's why I asked.
Hi there
In your opinion what’s the best boiler for a three bed detached house
With eight radiators
! N.100 please thanks
Be smart choose atag
17 installer access code
Be smart, choose Viessmann
And wait weeks for parts, no thanks 😂
