Brilliant video, what I would like to say 1.The bottom solenoid 119 ohm is fine even brand new resistance is same exactly as you said 140 plus or minus 10% 2. The yellow plug the diagram to test between one and no.2 pin the multimeter was on 1 and 3 , the 117ohm between 1,2 inch I love your videos alot of knowledge
I had a f28 reading on my vaillant boiler & wasn't getting any hot water or heating..reset it, held down the 2 top buttons while it said loading then released them. The little flame symbol appeared in the bottom right of the screen, the boiler fired up & hot water came immediately. Many thanks for this video, very helpful
HELLO! Very Very good explanations. Thanks a lot. Never seen an explanation so good in my life (drawing + what to expect + how to measure in reality). There is something that is not clear to me and I will need your precious help, PLS! The bottom resistor should be 140 OHMI (10% tolerance + or - ) you said. Plus would be 140 + 14 (10%) = 154. Minus would be 140 - 14 (10%) = 126. The meter is saying 119 (not between 126 and 154) => faulty resistor if my understanding is correct. Why do you say 154 and 185, please? Thanks a lot for your video!!!
Great vid mate. I had a problem with one of these valves recently, wish I had known this info at that point. Any chance you can confirm what the bottom ohms check should be (140 +/- 10%) and and what of the 6 pins are the correct ones to test between?
so useful, thank you, I like the close ups of the electrical tests. When you are testing the gas valve pressure, I presume it is at test point1 and not 2?
Totally agree on the fuel poverty, i see some shocking poverty. Scares me how little safety net there is these days and the government paints a picture of people milking it....the reality is the polar opposite
My heating boiler only has one plug on gas valve and resistance is 54ohms is it any good? Have seen other video which gas valve had one plug, he was getting 104ohms. It throws f.29 and f.28 error code.. but can be down to PCB as I check voltage should be 20V DC on start up, and later drop to 16V DC, but after 20-30mins starts playing up.
At 5.33 you say the reading was 1, 1 what? The actual display was showing meter out of range. If the reading was 1 it would display 1.something. not just a digit 1 on its own. Is your meter calibrated?
Yeah seen that one, normally there's one on the gas valve itself, I went to a f28 fault two days ago and couldn't find the pressure point on the gas valve to see if it was opening up

Thanks for the positive feedback, I’ve a hectic life and individuals like u give me motivation

there is two solenoids
Thank you Sir. Please keep them coming. Brilliant video. Thank you again for sharing your knowledge.
Thank u I really appreciate your feedback x
Should you not do air integrity with the case on?
Yes good spot!
Absolutely brilliant video 👍👌
Thanks I appreciate your feedback

F28 on a Vaillant Ecotec Pro turned out to be low water pressure in the heating system in my case. Increasing the pressure fixed the problem.
Yes, after awhile they can seize due to dirt etc
Great video thanks for sharing is there an app for resistances on gas valves leads etc
Hi
My reading is 0.746 on vaillant ignition lead . Is that ok or i need new one. Thanks
need a new one definitely

Good video
Muy interesante tu vídeo. Te sugiero que pongas subtítulos en español. Gracias un saludo desde 🇪🇦

Sorry I am partially deaf
Where did you put the black negative to test from?
for which component?
Can I ask where the gas pressure test point is on the sustain....i can't find it on the gas valve
Look on the gas isolation valve underneath
Yeah seen that one, normally there's one on the gas valve itself, I went to a f28 fault two days ago and couldn't find the pressure point on the gas valve to see if it was opening up
Flue integrity test with the case off?
No ?
Any on f. 61 on eco tec pro 28
I'm sure it's faulty gas valve
u guage see if GV opens?
@@warriorsofwarmth checked after 10mb on dhw, going to swap it out
