385 according to the book is low mains voltage...what have they done so far to solve it?

 

[micsey]

nothing because its intermittent i think its the board dry joints

 

[Gasguru]

I doubt it..modern pcbs are far more robust from poor soldering, compliance standards etc.

 

[micsey]

had 24/7 clowns out over ten times only thing the have not changed is the board?

 

[Gasguru]

Why won't they swap the board?
Have they run the boiler via an extension lead from a different ring circuit to rule out a poor connection, if the fault code is accurate (and many aren't) it thinks the power supply is dipping.

 

[micsey]

are you messing service is utter crap from them,think i will get the baxi one off repair cos no one has a clue

 

[Gasguru]

Why don't you run the boiler from an extension off the other ring circuit.

been out 7 times say everything is fine

Perhaps it is, it could be nothing to do with the boiler.

Go for it, if anyone should know, it should be Baxi. However I’d be checking what @Gasguru has suggested first.

usually the PCB with that fault code
