Biasi Boiler Repair Part 2

[@umark6695]

Tina's channel is very good. She is a very good teacher for anyone doing their ACS.

[@HeatingGeek]

Defiantly. :-)

[@experienceb4bob]

Thanks again very much to make such a great video and showing the resistors how they get loose and start causing intermittent fault...well spot and especially you are very careful with your words...no F words...so i can still watch and listen while my kid is sitting next to me....thanks for making such a useful and helpful video....god bless you

[@johnnysingh418]

Yep I been watching Tina's channel ' she is excellent aswel as it keeps me brushed up on the theory side. Some people hate Biasi boilers" but I find they are quite durable' especially the old brass diverter ones.

[@HeatingGeek]

I think they are good. Tough well priced boilers. I have never fitted one though!!

[@colinfleming2244]

One of the probs with them ideal minis was flow switch work on ch but not hw always a slight choke in divertor valve

[@HeatingGeek]

Yes, I had that several times. Sometimes changing the front of it would make it work for a while.

[@portalera3000]

Gracias a este video he reparado mi caldera. Muchas gracias 🫂

[@dardobartoli]

Thanks for this. I have kept my Biasi M90F going for over 17 years, and lost count of the times I have had to solder dry joints over the years. However, an intermittent fault, whereby the CH only comes on after running DHW might mean it's beyond economical repair. I do know that the Expansion vessel is leaking and loosing pressure slowly, but unsure whether this might manifest itself as that intermittent fault.

[@HeatingGeek]

No, the vessel won't cause this intermittent issue. It could be the main PCB or an NTC issue.

[@dardobartoli]

@@HeatingGeek As the expansion vessel is definitely knackered, I'll get it replaced. As for the main board it appears not to have any poor solder joints (unlike the ignition sequence PCB) but may consider changing. Int the meantime I'll investigate the NTC and if all that fails, will replace the boiler. Thanks for advice.

[@HeatingGeek]

@@dardobartoli Ok, Good luck with it. :-)

[@dardobartoli]

@@HeatingGeek Vessel replaced, along with new ignition pcb, then the main pcb, and both thermistors and have flushed the system, thorough clean of exhange unit... guess what, still the same issue. Only now everything works for longer and hotter (I think) before I get the dreaded fast flashing green light and no ignition. In short, everything works as expected and after an undefined period of CH and/or DHW the boiler goes off and the green light rapidly flashes. Then after an undefined period, run the DHW and all works again as expected. This M90e is like one of the family now, I don't want to replace it :-(

[@globaltimes7]

Thank you so much for putting out this video.... Bloody hell we been through so many so called specialist who advise was to just change the boiler... When the fix is so simple.... Not a diy job but know what the problem might be I can now look for someone competent to make the repair

[@HeatingGeek]

The gas industry is full of boiler installers. :-)

[@HeatingGeek]

Where are you based?

[@fordford1557]

My boilers got same problem if I change board do need to reset anything

[@Batmanski1]

I got same boiler, radiators is hot during use hot water. This is diverter fault?

[@HeatingGeek]

it could be. It also could be the plate heat exchanger being partially blocked.

[@robertvarga4534]

🙏👌🤔So, my green lights stopped working but still the radiator working&hot the green lights must be workng always or not neceserally?! 2nd.i used radiator key(I bought ebay £1.60) just take out the Pressure time to time from the radiator, but I realised it I taken to much pressure out from them, so the radiators aren't getting warm.., so on the boiler I'm done something the pressure came back, but I wasn't sure how much pressure is good up to number 2 or 3 or 4 or less, I think mine one it was 2.5 But after 2 days it was around 2 or the biasi boiler automticly selected itself the right pressure number?! TO BE HONEST AT THE SAME TIME I WAS HAPPY BECAUSE MY RADIATORS MUCH WARMER THEN BEFORE... 🙏👌🤔 3rd if the green light doesn't work its a small sign do something or the boiler could work without the green light?! And sometimes it happened before this so when we used the radiator /hot water time to Time we realised it we don't have hot water or radiators are not hot, so we turned off the electric & turn back on and some reason when we turned back the electric the boiler was on again & we had hot water & radiator was hot again, what are connections between them?! Thanks your time.., have a good day.. 🤔

[@wai-holi3861]

Hi, my bathroom is hot but my bedroom is boiling hot radiator, so what should I do pls?

[@HeatingGeek]

Sorry I didn’t respond to this comment. I didn’t see it in my feed. :-(

[@TheLeroyHenr]

How can I set a time for boiler to come on please and of.

[@HeatingGeek]

Sorry I didn’t respond to this comment. I didn’t see it in my feed. :-(

[@ek6868]

Tanx for the upload i thaught it was the pcb,your friend tina is an excellent teacher for someone who wants to learn about the gas industry I've already subscribed👍

[@HeatingGeek]

Nice. :-)

[@sarziryn]

Same issue with my boiler, the exact same 1 in the video. The pcb was replaced 10 months ago... now the issue is back? 😭 had no heat overnight for a week almost now. As you say the issue is intermittent so during the day I can get it going but I cant stay up all night doing the same 🤦‍♀️

[@HeatingGeek]

Could be the same issue. Very common.

[@jamesbroadbentplumbingandh1648]

Great video. Look forward to the video on fans and pwm

[@HeatingGeek]

I need to do so many videos. soooooooooooooon ish.....

[@andrewjones3606]

Hey daniel my bro has a similar fault however it the 2nd light flashing red and the 3rd light flashing green. No heating no hotwater

[@HeatingGeek]

Sorry, didn't see this.

[@splodders]

Thanks dude, you vids are awesome 👏🏼 you’re a great help.

[@HeatingGeek]

Glad you like them!

[@tonygreenbank8611]

The timer on these boilers have to be the work of the Devil. Not one customer knows how to use it, and I struggle.

[@HeatingGeek]

I don't know how to use it and I refuse to learn. No point. Absolutely rubbish

[@Hitngan]

Already subscribed to tina

[@HeatingGeek]

Good nothing like her channel to brush up with regs.

[@Razz60]

Again excellent video an yes ive already checked out tinas channel ive subscribed as she gives a good tutorial on the gas stuff very good to watch as its a vood way to recap stuff

[@HeatingGeek]

She teaches for a living so should be good for new guys and recapping before ACS.

[@Skeletoncrew46and2]

Tina channle is great,if your renewing your gas safe licence or for newbys! Top lady tina keep em coming.😁

[@HeatingGeek]

Yep.:-)

[@leaturk11]

good job...will pop over to Tina channel and have a shuffty.

[@gonzalomartinez1630]

Great Video, thanks for sharing.

[@HeatingGeek]

Thanks. for watching it. :-) I have a soft spot for Biasi.

[@themadhatter4761]

Thanks as usual, subbed Tina 👍👍👍👍👍

[@HeatingGeek]

Nice one. :-)

[@danielwilliams3162]

Hey heating geek, loving your videos, I think I've watched then all now. As a service and repair engineer myself, I'm just wondering if there's any other uploaders on KZbin that you rate please? Or could you suggest what the best training courses I could go on might be please? Thanks a lot...Dan :)

[@HeatingGeek]

I watch things like EEV blog and AEV. No Gas engineer stuff. I have enough of gas with work and Videos. :-) thanks for watching.

[@Taqqiyastar]

Very good mate You have gone all the way to prove that it is the pcb Your friend channel I did watch. But yours more accurate and logical approach towards fault finding. Tina mentioned to do gas rate on a logic that first you have to run the appliance for ten minutes for the injector to expand to allow more gas to pass Which this is not the way i was trained. We know we must not poke injector with a needle because the hole may get big But my theory is if the injector expand the gas flow will increase through the injector You and i know where the injector is located inside ideal logic so how does heat expand the injector I am confused but you have more experience can you through some light on to tinas video My intention is not to put anyone down but i want understand in logical sense So why do we have to run the boiler for ten min before we do gas rate a combi boiler You know you put the boiler on maximum demand or engineers mode to do gas rate and then gas rate on heating So i don't get it on tinas video But shes doing good work

[@HeatingGeek]

The time thing is in IGEM document. Not very relevant to newer boilers but the burners do expand. Watch my Glowworm Ultimate video to see some of the things you ask about. :-)

[@aj7303]

Who is Tina??????

[@MSKChess]

Tina is 2 awesome :D

[@HeatingGeek]

She know her stuff. :-)

[@jamesjulian]

It’s not against the law to repair a pcb but unless it been tested by pcb Manufacturer once you fit it you are asking for trouble, it’s the person who fit it is Liable if there’s a fire and if gas safe don’t prosecute you ,then customers insurance will take you to the cleaners!

[@HeatingGeek]

British gas fit refurbished PCBs and got Ideal Icos/Isar PCBs remade (which Ideal didnt like). Im not too worried.

[@jamesjulian]

BG are a law to themselves, just letting people know , only takes one time. 👍🏻

[@jamesjulian]

Have one of your pilot cleaning pin , use it all the time! 👌🏼

[@HeatingGeek]

@@jamesjulian BG make the rules with gas safe so I think we will see some changes come in sooner or later (Under the radar I'm sure). Maybe it's happened. Re soldering a resister is using the same OEM parts. I can see it causing a problem. Have you ever known someone go to court for it?

[@jamesjulian]

25 years ago they ran the show, I know rules are written after there mistakes and as the biggest gas Employer there working practices are considered , its British standards, building regulations and manufactures instructions,. And in manufactures instructions it normally says genuine parts parts only to cover themselves and that’s where people become unstuck , the ask is yes I have known people to be in court. I feel like the geek 🤓now . Have a good day

[@Mhuctchinson]

and the boiler still has no pressure, not once has he mentioned water pressure, it should be around 1 bar and is on zero, and I bet it still has the same issue after he left and charged a fortune to some unsuspecting member of the public!!!!!!!

[@HeatingGeek]

You have no idea.... Thanks for watching :-)

[@mrmagoo6966]

Easy in the end. lol

[@HeatingGeek]

Always. :-)

[@theworldofleia2955]

Biasi... no water & heating

[@HeatingGeek]

What?:-)
