Ferroli Optimax HE31C - total failure, no CH or HW !!

[maplecottage]

Not sure if anyone can advise but I have a 12 month old Ferroli Optimax HE31C which has failed over the xmas period - no heating or hot water Display was completely blank - not a sausage, checked plug fuse (all OK) checked inside the boiler and found that BOTH board fuses (250v 3.15A) had blown. Replaced fuses and boiler ran for a couple of minutes then fuses went again.

Can anyone advise what may have caused the fail - is it a component or more likley to be the PCB.

Any advice will be much appreciated.

Just spoken to Ferroli technical and they suspect the pump (although a bit vague really) ?? Would I be able to disconnect the pump and run boiler in DHW mode to confirm if this is the problem ??

Any ideas anyone ?? It's getting very cold in here

Best thing you can do is get somebody competant in to fix it,otherwise your gonna be colder a lot longer.

All fixed.

Isolated the pump and put 240v across it - blown fuse immediately. Got replacement Grundfos 15-50 from PTS, split head from body and replaced the faulty one in the boiler. Easy peasy, only took 30 mins and all is now warm and toasty !!!

Just noticed your post - you may be able to answer my question which is what temperature should the boiler (flow) be set at in this really cold weather? We've got the room temperature set at 21degrees but its taking hours to get to that and struggles around 18.5 for the first few hours when we switch it on.

Post dont make any sense they have 5year parts and labour on that boiler that you seem to have now voided.

Just read last post....

you have a 31C as well i guess. Turn the flow temp up until warm uop times are comfortable. How quickly your home heats up depends on so many factors.

But in cold snaps you need to have it a little higher.

.......and the moon is made from real cheese.

Sorry to be a bit flippant but have you tried getting Ferroli to honour it ?? I didn't have the time or the patience to get them to agree it was a fault they should sort --- with the weather doing it's thing, additional delay was not on my agenda. For the sake of a few quid, at least it's now all warm and cosy.

Thank you Registered Gas Man - I've upped it by 5 degrees and the rads are already much hotter.

Installed 5 of these piles of pooh and everyone broke down and everyone has been repaired, by Ferroli.

If you were going to do your own repairs what attracted you to the boiler. Obviously wasn't the warranty.

You're right

It wasn't the warranty, it was the price. Still, the old addages always hold true and there are so many that apply here - you get what you pay for or perhaps, you reap what you sow, or possibly fools rush in where angels fear to tread.

If it goes, it goes - the next one will be something more akin to a reputable make (if there is such a thing Probably a Vailant

Keep warm
