Potterton Suprima 30-100 PCB Kit 5111603 5102160 407750

After being correctly fitted by an experienced engineer, the problematic red flashing light continued so the PCB was returned as defective. Unfortunately, without an actual Gas Engineer report to prove that it's defective, this seller will only refund 50% of the purchase price. Better to just book a gas engineer from the start and not buy the PCB yourself. Look the company up on trust pilot and see the negative reviews for yourself.

I bought this for the same reasons that everyone does: the original PCB that came with the Potterton Suprima 60L boiler was rubbish, and after a while suffers from heat damage / dry joints etc. and ends up constantly getting itself into a lock-out state where it needs resetting. The various options are basically:- to repair the PCB (i.e. get your soldering iron out and start fixing the dry joints)- to replace just the PCB with a reconditioned one (which may keep it going for another couple of years before it goes again)- to replace the whole control unit with this item - a brand new PCB kitIn turns out that our PCB had already been replaced at least twice before, so I decided that rather than simply delay things with a replacement PCB, I bought this kit instead. You get the entire control mechanism (temperature knob, led and all), and most importantly: the entire PCB is actually enclosed to shield it from the heat of the boiler.The whole unit comes in a box with the kit, together with new electrode and earth wires (for both 30-80, and 100 models). This is important because you'll want to replace the electrode wire as well, when you replace the PCB.I got a proper heating engineer, who knew exactly what he was doing, to replace the unit itself (and I would strongly recommend this option rather than doing it yourself, unless you have experience with these type of boilers), and he managed it in his personal best time of 1 hour. Job done. £155 + £48 fitting = £203 ... far cheaper than I was getting quoted by other companies that supply the unit as well.The unit has been fitted now for a couple of months and is working perfectly.

Got this to replace the board only, everything else was working. Easy to fit, instructions are good. after fitting it the boiler started working again.

Bought to replace the original crap PCB, it worked for a while but now get the dreaded red light flashing again, almost daily.Don't waste your money and preferably don't buy anything from Potterton !

The PCB kit comes with very precise instructions that are very easy to follow. Taking my time to install so that I was sure not to make any mistakes and photographing each disconnection as I went so that I could check back if needed, the removal of the old PCB and install took me 90 minutes. It would have been a lot quicker with out all the double checking I did.On completing the install the Boiler fired first time and has run smoothly ever since.Buying this product and fitting it myself has saved me hundreds of pounds and thousands if I had opted for a new Boiler instead of trying this first.

Saved a fortune. Thought I would have to replace the whole boiler, but this has given us back our boiler working as it should

Great upgrade for our 10 year old Suprima 50L, Simple step by step instructions. Nice quality unit, the PCB is now fully enclosed. Took me about 2hrs, it was the first time I'd had the cover off the boiler and I was being super careful. You've mainly got to disconnect and pull out the old wiring loom and fit the new one. Lit first time, It's only been a few days, so it's too early to say if this has fixed the problem, but I've no reason to doubt this is a properly engineered solution that will work. Fingers crossed. Recommended.

Central heating works better than ever now
