Had the same on an ideal combi 24. Worked ok for years before it started to regularly lock out. When i tested found it running at 5mbr when hot tap was opened. All 15mm with loads of elbows. Replaced with a track pipe due to awkwardness of the run. Sweet as a nut now
While working as an engineer for Baxi I had to go to a job at my next door neighbours house (Im only surprised the office didn't book the job to an engineer that lived 40 miles away!). The guy was a self employed plumber who had fitted a new Baxi combi in his loft. The job came in as CH ok but no DHW. Inlet pressure was dropping way down when a hot tap was run. He'd fitted his boiler and not even checked his inlet gas pressures.
Great vid mate. Just shows the importance of basic checks before jumping too far ahead with probable causes.. Always nice to see approaches of different engineers. Look forward to more of your vids..
Carl plumbing & heating Thanks very much, the idea is to keep posting vids if there are enough people interested ? And also to do a Plumbers weekly diary if watchers are interested I will start doing that in the New year.
Had exact same issue on an CDI combi yesterday Shale in gas Valve and gas pipework causing lock out in high fire ...had to remove gas valve and clean out inlet pipework to solve it ....#suchfun
Benjamin Frost much appreciated 👍 I have a Digital Anton .. it’s just so accurate no one believes it.. great for wb and the like.. checking hex if it needs a clean or bearing plate needs a look. You can never have enough tools in this game mate ! Thanks for watching & spending my money !!
Great vid, I'm glad someone else gets same probs as me ! But praise where praise is due you're so much faster. Customers dont always tell you the whole truth. If only 2 years old that boiler is still under warranty. Strange the customer didn't phone Worcester to fix for free ?? Which usually means their mate/ dad/ family friend fitted it and dont want to get them in trouble. And these things never usually happen one day. Its been like this for ages or else same family friend changed the electric hob over for a gas one and tapped into their own shoddy workmanship and it all went wrong from there !! That and the Gov went wrong. Perhaps same family friend messed that up when they tried to increase pressure from there. Mystery. Hope you charged a profession rate for that. Only the customer knows what really happened and they're not telling..!!!
Excellent video you should have tried chopping up the old 15 mm pipe I’ll bet it was full of flux I’ve seen it before and literally scoop out clumps of it
Dr Pipe I really appreciate these videos you make mate, I’m pushing to get back into breakdowns properly and I think the most important thing I’m learning from your videos is to take my time and go through it practically.
Must of been fun times explaining to the ‘but it’s been working fine since installed.’ Customer that they had to lift up the carpet and run a new feed....
I once had a similar fault, scratching my head before deciding to lift the floor. 22mm from the boiler, under the floor into 15mm for 15 meters, the back up into 22mm for 2 meters to meter. The mind boggles. Still, a nice new 22mm run put in, works now happy days 👍
Perhaps the 'weak' mixture caused the Gasses to burn too hot and over the years damaged the Electrodes, so although they were able to work with a poor mixture initially, eventually they failed. But when the pipework was the correct size and the correct stoichiometric ratio was achieved the electrodes could cope with it?? I note that you did have ignition at one point, so possibly the flame detection electrode....
ok, so it doesn't really make sense, but it is what it is and you got it running.... what was the actual pressure at the end, keep it real cheers fella.
Nigel Brooks 20 mb I think ? Was a long time ago.. and I never watch my videos after editing .. I’m sick of the sight and sound of myself typical 4 hrs a week edit for 2 movies. Thanks 4 watching
It wouldn’t drop to 0 surely on 15mm, meter regulator fault or could be something restricting gas flow trough the pipe when gas flowing if that makes sense
InoHeat Limited watch vid.. reg replaced check 👍 gas valve checked for blockage 👍 pipework none found 👍 what u saw is what u got 4 years on thanks for watching 👍
Although stupidly undersized my guess would be that there was a blockage in that 15mm also with wp being that low. Which is why its worked for years till it failed
Danny C I would like to say that’s the case.. but I took all the pipe out in 15mm inspected it... NOTHING it’s a mystery ! I find out of ALL the manufacturers WB are the most temperamental .. any manufacturer that has a go slow for 20mins after a power down is having a laugh.. wb the only 1 I know. Thanks for watching.
@@drpipe really is a mystery then mate. Lowest ive ever had on one of them is 2mbar and it was still working lol. Pipework was chocca with shale the full 32m run. Keep the videos coming mate its good to see how others work and have picked up a few decent tips from you 👍
Danny C fantastic mate I’m pumped that guys n girls get stuff out of this content.. I’m just an engineer trying to get sh t done the best I can and help people learn n laugh hopefully. Just the same as you guys just with a camera and up late editing again !
@@drpipe exactly mate i find that sharing ny knowledge with aprentices and engineers with less experience helps me in return because it refreshes the basics in your mind and they question you. Just wish i wasnt camera shy haha. Giod luck with the channel
Enjoying your content. Keep it up 👍 I have a conventional system, boiler is an Ideal Classic. All working fine but plumber has recommend changing for a combi due to its age. Would you upgrade given its 15/20years old? If so, what’s your favourite brand of combi? Cheers Cameron
camladere2k8 Get an old skool heating guy to service it.. clean out the loft tank couple of shots of inhibitor. Maybe a pump one day and a possible gentle flush. Sometimes I have known people to turn the F/e tank off upstairs to keep an eye on whether system has a leak also if the boiler were to go it won’t keep refilling 👍👍👍 easy access it’s no trouble . Combi will never last 20 plus sorry. If you do have a new boiler make sure it’s well flushed and a Magnaclean fitted not another make 👍👍
Dr Pipe cheers buddy, think I will keep hold of it until it’s well and truly dead. Seems like the engineer is just trying to make excuses to flog me a new combi. I guess it’s a case of they never make them as good as they used to. Thanks for the advice buddy, keep up the great content. Really enjoy watching it, can see you making it big on here 👍👍
Boiler keeping going into lockout on my biasi advance 25c. Er 01. Cleaning the spark electrode and the flame rectification once and it worked. Now it doesn't matter how much I clean it while a file/wire wool it won't rectify the problem. What could it be
Blue Dwarf this was one of my first videos 6 months ago.. the mere fact I show each step is the thought process.. in theory it should make perfect sense.... low gas pressure any1 of the things I show cold have been the reason. Hope it makes sense 👍
I was at a greenstar junior 28i today. CO readings were where they should be, inlet working pressure 22mbar. Gas rate was coming in at around 12kW. Any idea what the problem could have been?
Have to be Honest and say “ I have no idea !” I spoke to wb they had no answer and I cannot work out why it failed years later.. that test was without the gas hob on !
Had plenty like this but there is no way that worked ok for any time at all, had to put a 28 mm main to a boiler last year, it was a 30kw boiler 24 metres from the gas meter on a 15 mm main, it was tripping out more then a junkie at a free drug party, the polish chap who originally fitted it refused to sort it out. It works ok now though.
Great video tanx for the upload,i taught gas valve but was amazed to find the fault with hidden undersized pipework i wonder who installed and commissioned the boiler? Plz Could you upload some more fault finding videos I've just came across your channel and subscribed tanx👍
E K Glad you enjoyed the video and have you on board, there are stacks of Fault finding vids on the channel take a look around.. Vaillant main etc hope you find what your looking for and loads more to come ! Only been uploading for 6 weeks ! Thanks for watching
Jack Milligan .. it could have been any one of the items shown.. hence the reason for showing the video.. but it still doesn’t answer the question of why it worked for years before failing on that day ! We will never know.
Paul Turner I have an Anton works great... but it’s too quick to show up on this hence the standard type looks far better on camera 👍 thanks for watching.
Could have been worse, the boiler could have been in a confined space!!
Good job fella, Thank you!!👍

I don't think the warranty would cover an installation fault, surely worcester would deem the warranty void most likely
I think you're right.
@@TheLabanFamily they wouldn’t know it’s an installation fault unless they came out and did same checks that were done in video.
Excellent video you should have tried chopping up the old 15 mm pipe I’ll bet it was full of flux I’ve seen it before and literally scoop out clumps of it
Salim Khan I did.. Nothing in it sorry
Very informative
Thanks
Great videos .thanks .it is really helpful.much appreciated.
Hamid N pleased 👍
How many of you Thought its another gas valve change Job ? leave your comment below ..
14mb is the lowest rate they can work at so Worcester say
I noticed the space at the side of boiler is it against the regs?
@@mmack3286 only needs mm at the sides, everything comes out straight towards you.
After finding it was clear I would have been scratching my head for sure
Peter Hyatt don’t give up

@@drpipe thanks for your response, the reason I asked is because I'm training to become a gas engineer so trying to understand how things work.
Blue Dwarf 👍🙏
Maybe there was something in the old gas pipe that you replaced? Debris or something? Or did you check that?
Nothing found wrong size
Meter gov lockout?
I was at a greenstar junior 28i today. CO readings were where they should be, inlet working pressure 22mbar. Gas rate was coming in at around 12kW. Any idea what the problem could have been?
Sounds like blocked heat ex, just think you only had co readings at 12kw and not 28kw so you didn't have co readings for max
How has this worked at all if the pipe work fault has been there since cowboys left
Have to be Honest and say “ I have no idea !” I spoke to wb they had no answer and I cannot work out why it failed years later.. that test was without the gas hob on !
Maybe they finally cranked up the temperature.
What changed though as it had been working. Would understand if hob was on full pelt, to cause a lockout.
Ken Devanny If only we knew bcos there was no blockage no issue with governor and Wb had no idea either..... mystery 👍 thanks for watching

No doubts about accuracy or calibration with this proven type!
