Last Fault A 4098 OVER VOLTAGE

[AlexS]

This keeps happening to me, rarely affects both units at the same time. I've raised a case, but not got any help so far.
The last time it happened my mains voltage was 237v, according to my plug in monitor, so not over voltage by a long way.

To me it's clearly a fault, be it hardware or firmware.

Could you check if the power cord is all the way into your Devialets? It may be a pure coincidence, but after this fault happened to me, I did discover that the power cord was not fully in. The problem has not happened to me since adjusting it. Mind you, the voltage in the USA is 110 (which makes the fault even stranger).
