Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
how can you tell when the pcb board on a COMBI is broke?

Power in to the PCB but b*ugger all coming out! the whole boiler appears dead. I`m not a spark by the way but I believe if you have 240v coming in from the socket and nothing coming out it may be pcb, there is also an inline fuse on the board ( little glass chappie) sometimes they blow, I think they are about 2amp, but it`s best to check your MI`s. I`m not a professional.
There is a sequence of fault finding checks that we follow which helps us do a differential diagnosis. This varies from boiler to boiler. You are asking a lot with a small amount of information.
ok sorry its a vercarra combi, green light is on, no fault indicating lights atr on, and the noilers not attempting to go to ignition at all, but i had the same with a worchester not so long ago but the red fault light was lighting up on that one and it turns out that it was the board gone, so i was just wondering if it could possibly be the board on this one thanks
do u mean vokera? what model? heating working or not? hot water working or not? r u an engineer?
There could be anything wrong with your boiler. What makes you think its the PCB.
Theres a shortage of information in your post and the fact that you cant even spell the make or at least come close doesn't inspire me with confidence that we will be able to help much with this

To identify boiler faults you need to have a logical mind and think about situations such as our need to know what boiler model you are asking about.
In addition you need to be registered to work on gas appliances.
You apparent inability to spell or to check your spelling does not bode well for you to have much success in diagnosing PCB faults.
Can you play chess?

so i was in a rush and spelt few words wrong, get a grip on your self. only asked for some advice, and if your not going to bother giving me any the please don't post a reply you ass. and for your information i am a gas safe registered engineer, but i mostly deal with installs and not maintenance, not my fault my company doesn't cover that area of work
If you are registered then you should post trade questions in the closed combustion chamber part of this site where we will try to help you.
On an open forum like this, it just indicates to the public that there are some people repairing boilers who dont have the experience they need.
Also being rude does nothing apart from reflecting badly on yourself.

Will probably get same abuse there for not knowing everything, give me a break, the only reason you are posting, same as every so called engineer on this Forum is to impress fellow engineers! The pinnacle of that self idolatory is the combustion chamber for God`s sake, you have been given a forum, closed to your Godly selves yet you feel the need to keep banging on in here. Stick with yer little chamber, people like you in there.
Priceless.
Charlie, the closed forum is there for discussion of gas matters among other gas engineers who may have a problem or need assistance or even have something useful for other gas installers. The purpose of this forum is to assist general visitors with their gas inquiries and malfunctions.
I rarely post on this forum or the closed one for that matter as I like to take on board what my peers have to say. Would certainly post if someone was going astray, never if I was not sure of my facts.
Have been a member of this forum since December 10 2003 but have only clocked 2380 posts. Clearly not many posts in six years not because I am a novice but fearful that a handyperson might injure or even kill himself following what I might put on an open forum.
Looking at you posts, while you are confident that you are up to speed on what you pen, I somehow feel you have large gaps in your understanding of boilers and system. In saying so, I do not wish to be rude but am appealing to you better nature to be cautious as your advice might be taken by someone out there for gospel and end up missing a limb or life.
OP, a PCB is not an item I change often (as a heating engineer carrying out boiler repairs and servicing). Just because there is no output, does not mean the PCB is duff. It has to act on number of inputs to give an output. Proper way to establish if PCB is faulty is to get to know what it is designed to do and then check the conditions that might be causing it to hang up. only then change it if it indeed is faulty. Not for the first time have I visited a customer who had the PCB replaced without curing boiler defect. In fact there are PCBs out there that will be killed by a faulty component attached to it if testing is not carried out properly.

Really
The purpose of this forum in my own humble, non important view is to give advice if you can, to someone asking a question, not to give them the third degree about qualifications, how dare you, you are stupid etc. It is a forum to help people. Let`s try to keep it that way.
Well put, very fair point, but as I keep saying, I have/would not give out dangerous advice.
No, it has to have an input of 240 volts.
Normally it runs the boiler and if there is no voltage from it, the boiler won`t work.
