Potterton Suprima boiler fix

[@johnnydxxx]

Thanks Julian, Ordered refurbished one from Ebay. Came next day, 10 minutes to swap out and boiler fixed. Saved me a fortune. Cheers!

[@TamMcKee-z3k]

Thanks Julian sooooo much for your brilliant 'easy to follow' video. Went onto eBay bought refurbished Suprima 70 controller (£110) and arrived, fitted, hey presto - warm showers and heating now back in the house. 10/10. Orrrabest - Tam fae Glesga :)

[@christinegooddy1573]

Thanks so very much, Julian. I’m a female who lives alone and I knew it was a circuit board problem. Delighted to find your video. You have an engineers mind. Thank you 🙏😘

[@stevieweeks2407]

Thanks Julian had the same problem as you bought a second hand one of e Bay. Followed your instructions and now have a fully function potterton now Thanks again Steve

[@michaelgolf6941]

Brilliant explanation of how the Suprima boiler works. Even if your not a DIY guy at least you know what the heating engineer charging you for. It's best to have an understanding of your system when making decisions that will cost you money. Well done and thanks for the video.

[@Neo-mw1pp]

Have my Suprima 50 now for 20 years, in that time ive replaced the PCB 7 years ago and the cast iron heat exhanger that rusted from the inside out about 4 years ago from not cleaning the system. I drain the system now every year or two pre-season and add new inhibitor. I expect another 10 years plus out of the old girl yet, great boiler!

[@tonyhealey8977]

Good fix at a good price. I have a suprima 70 that failed. I re soldered all joints on the circuit board which cured my fault. I read that they reduced lead content in their solder which caused dry joints.

[@michaelnixon4856]

Concise well explained and useful video with exactly the same error as on my potterton suprima 40. Now off to order the exchange PCB 😄👍

[@godfreydesilva5222]

Excellent video. It does give a message how to check the boiler. Thank you.

[@mpeer8765]

I have a question regarding the orange light fault. The video talks about the boiler doing into Lockout. But what about Carbon-Monoxide spillage (Leakage)?? Would really appreciate an answer

[@Thereishope664]

My Potterton Suprima is like Triggers broom. Three fans, two igniters, I air switch, I heat exchanger. But no PCB. Its 19 years old and going like a train.

[@Paul-ys8wg]

Great vid ...thanks what company did you use on ebay. I have similar issue on suprima 40 and looking at the advanced exchange service on ebay. thanks

[@julianjones7914]

Hi. Thanks. It was Adlink UK. Rgds

[@jagjitghattaure1670]

That was a brilliant demonstation of the problem. I am having the same problem with my boiler. And would be so please if someone could help me sort it. I thought it's the pump so I have purchased the pump. And wish to fit a magnaclean too and change the two valves.

Thank you that was excellent.I have the exact same boiler and much the same problem could you possibly give me the name of the company you purchased the unit from .Thank you ,much obliged. Mike

[@lemonhead113]

I have a question. My boiler seems to be on alllll the time. Why is that? I want to cut my gas bill. Do I just turn it off when not required?

[@peterstubbs5934]

Good video although I have the opposite problem.. Intermittantly (but often) the boiler stays ON and wont switch off, obey the thermostat or the timer. The only way I can stop it boiling us alive is to switch off the power to the boiler.

[@karimachandler2409]

i have the exact same problem - did you get anywhere with yours? Thanks

[@doitcom]

Hi Peter. I'm having a similar issue. The boiler is turning on randomly and heating the house and ignoring my HIVE completely.

[@gingerrussell]

I think I had the same issue. Went out and heating stayed on all day. Ended up replacing the motor switch thing located above the pump. Seemed to do the trick. Product code 76959 on Screwfix. Old one was stuck open.

[@doitcom]

@@gingerrussell my boiler went pop on Friday. So new combi being installed currently :(

[@tokomac7728]

Yes it is working…what about safety devices in an case of flame loss in an case gas valve still open ….as trained gas safety people we must check flame rectification device is it putting boiler in safety locking mode (red light)????!

[@garywilson6047]

Which seller was it you bought the pcb from? Thanks.

[@theeroom]

Question: can I increase the boiler flame to heat up the house quicker? Or is there risk in causing issues

[@ronnieroo227]

Yes, it's a screw type fitment right at front under the second screwed closed cover. Our engineer did it after fitting new gas valve.

[@Moodymongul]

I have this exact boiler. Can anyone tell me how the cover should be opened (where the fan is located). The boiler I have here seems to have a cover thats been wielded on by the last guy ;) I just wanted to check the 'correct' way to remove (there are no screws showing on the cover) Thanks

[@Moodymongul]

np. figured it out. You have to remove the outer casing, surrounding the pcb assembly, first. Doing that, gives you access to the two screws that hold the main cover in place (the cover that hides the fan etc)

[@moolindabumble9251]

Mmmm my plumber changed the PCB board and it still isn’t working. It flashes amber green, keeps clicking and then flashes red. It’s very, very annoying. 😭

[@Михаиллеви]

Could be the pump. My pump went. They have a shelf life. The boiler fires only for about a minute and the heat just reached the pump but as it was not being pumped and circulated the overheat thermostat on the boiler operates and stops the boiler from boiling as the heat is not going anywhere where it should and the boiler senses this and will overheat hence the name of the safety device. Overheat thermostat.

[@toffmcman9505]

Changed my pcb as well but still turn in and goes off after couple minutes, I guess is short cycle tho . Pump working fine as there is no noise and I can hear the water circulating in the system , some I hear airbuble sounds I did bleed the rads but it’s still has same problems

[@garryhills8648]

Yes mine was pcb there a man on eBay who solders joints With lead solder as manufacturer doesn’t use lead solder

Thanks Garry, why is lead solder important? Pls could you say who you used. TIA

Dear wonderful Potterton gentlemen, l have been told I need to check my water pressure on my Potterton Suprima boiler? I told him there isn't a visible one, could you please tell me where to find it? (PCB board easy enough, l have done 3 on our 20 year old boiler) .

[@andyliv78]

There isn't one. It's not a combi.

[@Михаиллеви]

If the system is unvented meaning an expansion vessel has been installed in place of the loft header expansion and central heating feed tank the system will have a pressure gauge installed but separate from the boiler.

[@gregchrisp2177]

can you make a video on how to put into service mode please

[@julianjones7914]

Sorry, Im too busy to do that at the Mo!

[@dukedepommefrites8779]

Hi Julian, many thanks for the video. just wondering how the PCB is behaving after a year? Our boiler is 20 years old, ok til recently, would you know why these faults start to occur over time, believe faulty soldering is an issue but why only shows up after say 20 years.?

[@dukedepommefrites8779]

Glad to hear. Spoke to a gas engineer across road, he says not worth upgrading to new condensers. Apparently not serviceable, the old pottertons etc can nearly always be repaired.

[@mechtechmechanical1571]

common knowledge in the gas world that the pcbs fail

[@Михаиллеви]

On these boilers which are great otherwise

[@CarlGuymer1]

Very logical...BUT...you should be gas safe registered to work on systems like this...looks like you got away with it this time....but other people watching this video who get ideas may not be well educated...and may do dangerous work.

[@hoppy1970]

Unless you are gas safe registered, it is illegal to "disturb a module that controls the combustion process". I believe it's a maximum of £15000 and two years in the pokey. I suggest you delete this video.

[@julianjones7914]

I can only guess as to why your comments are so incorrect and misleading! If you contact GasSafe, they will confirm that the work I have done is perfectly legal!!

[@RoobieRoo2]

​@@julianjones7914 Again you are correct. If the work required only involves the replacement of a non-gas component such as a water circulating pump or central heating control valve, housed within the boiler’s decorative casing, the work could be undertaken by another competent tradesperson e.g. plumber/electrician. Providing the work could be undertaken without having to break a combustion chamber seal!

[@garywilson6047]

@@julianjones7914 Hi. Can you remember which seller you purchased the pcb from please. Thanks.

[@Михаиллеви]

All electrical work except Part P work which is basically Bathroom and then in the zones, consumer unit changes and new circuits can be conducted by anyone as long as they are competent. This bloke sure is.

[@hoppy1970]

@@Михаиллеви This is NOT electrical work as per BS7671. Any component that affects the combustion process must ONLY be worked on by a gas safe registered engineer. In the case of the control module, Regulation 26(9) MUST be carried out after replacement. I am a gas engineer since 2011 and electrician since 1990. Thanks.

[@chriswareham5763]

It is against the law to remove anything from the boiler you must be gas safe registered It’s there for a reason!

[@ravindersidhu9417]

You have to be gas safe to work on boilers

[@julianjones7914]

My understanding from 2019 regulations is that you can carry out work on your own boiler providing you do not interfere with the gas carrying components! Furthermore, the last gas safe operative that did work on my gas boiler left it in a very dangerous state- so beware who you employ even if they seem to be qualified!

[@sambda]

Only on the gas side - you can fix the electrics yourself.

[@leightonedwards1322]

Shouldn’t be taking the cover off the boiler you have to be gas safe registered, read the regs, if the cover is not correctly fitted back on it will be in safe, another thing is you can’t test a pump by putting mains to it, how can you tell if the propeller is working? Is is why we spend thousands of pounds of course to be qualified! Leave to the experts and come of giving people advice, you will cause a major problem

[@Михаиллеви]

TBF he did not touch the combustion chamber. Wiring in mains to the pump was a temporary test to see if it worked. It was obvious it worked as hiw would the system have stayed on at all if it didn't as the overheat thermostat would have stopped the boiler working fairly promptly if it didn't. You have to wonder what advice the well qualified boiler servicer gave though !

[@cowardsallaround98]

Do yourself a favour and get a new boiler and watch your gas usage go down A 1995 boiler is a danger 26 years old are you sure

[@Neo-mw1pp]

Incorrect.

[@Михаиллеви]

These boilers and the cylinder system are work horses and rarely malfunction and then it is a simple fix. We spend more money fooling with combis and servicing over their life span. Boilers have become like cars. Leave it to the experts so they can mint it
