The OP has not made clear at what stage he is at in the EICR. If he was talking about while doing the EICR, in my view this should have been noted and a code attached. As he asked what code I assume he is in the process, in which case he should not have investigated but just put a code and brought it to the attention of the person ordering the work. After that if the person asked he should have investigated the fault observed. I think as Lucien has elucidated exhaustively the possible mechanism that may cause the trip to operate with the test button it is not within the scope of an electrician to investigate the cause due to this being a step too far for our pay grade. I suppose sending it back to the manufacturer might throw light on it? Or we just take the pragmatic approach of replacing it. It might be that a type A is needed due to hysteresis in the case of the test button not producing enough fault current for all I know, would not be too sure of how to test for that though. I could assay that if there were a number of computers/electronic equipment it could well be the case but that is merely an educated guess.much investigation as it reasonable to do.
