Glow Worm Flexicom HX pops on ignition - common fault?

[vexation]

can't remember now when they changed the heat exchanger design. I used to know. But its easy to tell from the shape of it. From a side profile of the heat exchanger the old one is flat down the front and the new design concaves slightly like a shapely woman. If its the earlier one probably you need a new heat exchanger to cure the problem.

Thinks "Swiss Tony" - Lucky me, mines like a shapely woman Just (another) new electrode is going to fix this - now I can see where the electrode is arcing through the ceramic to the metal base. "Made in Italy" is stamped on the part. Maybe a clue as to why the spark goes off prematurely?

just been unlucky with the electrodes then I'd say. they arent most reliable but certainly more than that usually. Fitted a couple of flexicoms myself and not heard a peep ansd when i was doing warranties on them it was rare to go to the same one twice.

Made in Italy, mmmm, same problem on earlier Baxi solo's, guess where the part was made.

Interesting, PEDANTICVINDICTIVEMAN. Really cheap & nasty bit of junk. The ceramic isn't able to hold up to the 10~20KV needed to jump the 4mm gap. I added a diagram showing how it fails in my original thread.

a large majority of heating parts are made in italy and france now, even for german boilers.
