Good demonstration of persisting with a logic based approach to fault finding. Oftentimes we are seduced into relying on ‘matching likely solutions’ based on experience and/or progressing through the easiest (shortest time) potential solution to the most difficult (longest time) potential solution until we stumble upon success.

Update: I replied 1yr ago that your fix appeared to help our issue, and indeed for a year or so its been fine. However a few weeks ago, same S.54 and the random F.24. (S.54s started to come daily) I re-did the extra earth connection but still happened. But, when working boiler was fine. Taking this "cause" to the next level, I replaced both NTCs pre and post HE (ebay £9 for 2x genuine!) but wrapped an earth cable around so it was compressed on the final turn (I tried soldering to side, but solder didn't bind). I then took the ECU earth off the boiler chassis and joined directly to my 2x NTC earth cables in a wago 5-way, then another cable back the boiler chassis. Theory being, a good/known/clean/common earth between both NTCs and the ECU. Since, **ZERO** trips! Maybe new NTCs not needed, but thought as I had to remove them anyway I'd swap them out. No idea if there was a faulty one, or intermittent fault, but for £9 - why not. So it appears you were on to something, so thanks again, and perhaps "my" fix is the final step if it keeps happening!

You are an excellent fault finder. That was inspired thinking to realise that. You have to know how something works in detail in order to work out where the failure occurs. It’s a treat to watch a proper engineer work logically to a conclusion . In telecoms we call that fault and intermittent HR dis ( high resistance disconnection ) causes noise, faint speech, adsl errors, one way transmission, ring tripping.

HG you're a genius, love this solution. Perhaps you could throw some ideas at my issue? I've got an old Turbomax 828E that was forever failing so I took out the Valiant "insurance" 4 years ago and the main H.Ex had failed. It was replaced along with almost every component by insurance engineers... the following year F.22 randomly appeared so I changed NTC's (twice) and all was well... then F.22 started again so I earth-strapped HEX. F & R pipes to chassis (thanks to your vid) and all was good once more... for a while, but then F.22 crept in again. When boiler first fires it happens within about 10 mins but as boiler/CH water warms up after re-setting F.22 a few times it goes for many hours, sometimes for the whole day. Sometimes it will fire up in the morning for a few house before F.22 oh, and if I hook up diverter valve for H/W it will ALWAYS F.22 when DHW draw is finished. (we don't use DHW so I simply unhooked actuator head from diverter valve) PCB, Fan & Aqua sensor (which I've checked voltage output and it's good) are the only things not changed so very reluctant to scrap it now as it's pretty much a "new" boiler... :) Any ideas come to mind? Thanks in advance.

@@HeatingGeek Just reporting back to say THANKYOU. I'd become so fixated on it being electrical/mechanical your suggestion put me back on track to the simple solution. First off "competently" checked gas pressures to rule anything there out but they were spot on so I drained boiler through service valves and quite a bit of magnetite came out. Flushed burner through service port with some X800 siphoned from bottle on top of boiler then ran the rest + another bottle of the same around the system for 3 hours which didn't lock out once. Drained and flushed twice and refilled with X100. Everything has been perfect since. I was even able to re-hook up the diverter valve actuator as DHW always caused lockout (commercial building so didn't need HW). We have heating and hot water and all thanks to your "blockage" comment. Nowhere on the internet or elsewhere has blockage been mentioned as a cause for F.22 on an old Turbomax Pro 820E - Been collecting quite a bit of magnetite in the pre-filter which will hopefully stop any further blockages. Adding this not just to say thanks but hopefully it might help others looking to keep a reliable old non-condenser going for a few more years. Thanks again. :)

They should stop designing electrical components that use the pipework as ground as all copper over time especially copper that gets hot and where oxidation is more common eventually looses conductivity.

Like a car with a faulty ground connection due to corrosion results in high resistance in the current path (actually there are three options 1. short, 2. open, 3 high resistance). You should check, if you can measure the high resistance from the NTC to the PCB, maybe it will be able to provide an indicator for future problems. Anyway this was excellent detective work.

Shame your title didn't have S.54 in - I'd have found it years ago! Our boiler has been tripping with S.54 for YEARS. (never drops to F.24, or never seen to, but F.24 is stored in error log - -assumed before I moved in). And in that time, pump, DHW HE, diverter valve all changed and its still randomly playing up. But only recently have I seen it drop to S.54 on heating (ruling out DHW HE and diverter valve). The main HE was next on list, but boiler is otherwise perfect (having a shower and watching, as soon as S.54 display, flame-out reset and it cuts back in and can work for 10 mins or so). So wasn't convinced it was physical. Bought a HE off ebay which came with 2x NTCs (which read the right resistance) so was going to swap those first and clean contacts. Hadn't considered the earth return. But this is the most exciting prospect!!!!! Thanks :) FULL RESPECT to your approach - logical diagnosis is a skill not known to many, so well done for applying and sharing. Will try this later today

Well done in working the principle out, BUT: Did the CU have a RCD or RCBO? Did you know most of F.24/jumping temperature displays are due to external influences onto the boiler chassis? Most common cause of this fault is failing elements in ovens, kettles, electric showers, N to E faults on supplies etc etc. Also boiler chassis at different potential from main earth bonding. Measure N to E at boiler PCB, must be less than 5VAC and not fluctuating.

Yeah I know what your saying, but this one and another one I have fixed have both been this issue. I did have one in N11 that I never got to the bottom of that could of been an external issue.

I haven't had this issue where external stuff caused it yet. I will watch out for it though and the RCD/RCBO is a good thing to look out for. :-)

Just answered my own question. Watched the vid again and saw the bit where you say the wire doesnt go to the ntc it goes to chassis. Weird. Next time I see one of these I'll look out for a wire. So is the wire just linking from position thirteen to the earth clamp in the boiler? I totally get the concept of this, just need to see where that white wire starts and finishes. Weird that the pipe (and other metallic parts) act as an earth on a component that relies on changes in resistance to operate correctly. It's kind of asking for trouble down the stretch. Anyway, this video is quality and helps us all think about why a machine isn't working rather than just knowing how to fix it. 👍

@@JD-gi9pl The white wire goes onto the PCB and onto the chassis. Vaillant stopped using this method on this boiler. I haven't really had this too many times but when it happens I know what it is. Cars use the chassis as an earth all the time. It works for them fine. :-) Glad I got you thinking. ;-)

I would take its all apart and clean all the joints on the pipes and diverter and then refit it all. That would be the true solution. Or an earth bonding clamp above the diverter and a wire on the chassis screw.

I recently have had a number of parts replaced on our Turbomax Plus 828E combi boiler over the last few months. The boiler is 17 and a half years old, and I have had to replace the expansion vessel, heat exchanger, NTC single wire, pump, and PCB. There is also a slow leak from a non return valve now, so I am wondering if this boiler needs to be chucked after many years of reliable service? The F24 only occurred two weeks ago, but even though the single wire was replaced last week by Vaillant, it seems that there are number of failed issues and leaks happening in the process.

Does the Flow and Return side NTC’s fit in to a closed end thread or actually through the copper pipe to contact the water ? I have a TURBOMax that looks like it has white jointing compound coming out the side of the NTC threads, so I’m wondering if someone has ‘sealed’ them in and this could cause an increased resistance. If the NTC’s go in to a closed threaded coupling, the No sealing should be required.

The NTC is in a dry pocket. Sometimes heat sink compound will be put on the tip but PTFE shouldn't be used.

So good that you take time to study. I have an issue where i have the Turbomax 28, not the pro with the fault panel. Anyway my issue is that when preparing for CH, it often tries to start x 3 then reverts to failure mode and has to be reset. If i have water demand, it runs every time with no failure. I have noticed that if i reset the boiler and turn on HW demand, run for a minute then turn off HW, the CH demand will run and fire as normal. Only after heating temp is made and boiler switches off does the cycle happen again. I have had an engineer out and he has replaced the Dviverter Valve, same as in your video. That has not fixed the issue. I dont want to be chasing fault after fault with replacement after replacement. Its an expensive non repair. Do you have any experience i can point him in the direction of?

Yes i did, it was a strange solution though. The thermocouple was replaced and the issue disappeared. It doesn't explain the correct operation on HW demand but its been fine ever since.

Have you ever checked the Modulation Current d.37 on the TURBOMax during the run cycle ? I have one that is running for just 30 seconds or so per cycle and I’m thinking it’s going full rate rather than modulating. D.32 readings - 0 to 111 (mA) for Ignition sequence (6 seconds), - Then 13 mA for 28 seconds of run, - Then back to 0 for pump overrun. Target temp of 70 is being reached by the 30 sec cycle. Any thoughts on such a short cycling ? Is it normal or should the burner be modulated down and the therefore a Gas Valve Modulation higher modulation current should kick in ?
@HeatingGeek
7 ай бұрын
Just check the gas pressure. If the mechanical gas valve isn't set up properly then it doesn't matter what current you have. Someone could have set up the minimum to 10mb and the max to 10mb. the boiler will not modulate then
