I’ve contacted the ‘breakdown service’ (don’t know if this is correct English) and they were able to check the voltages in my house remotely … instead of 3x 230V they saw that I’m currently supplied with 2x 200 and 1x 160V
The washing machine is also displaying an error code which is related to not enough power.
You’re lucky it was under-voltage. Over the Summer we had a big over-voltage of well over 400V. It was very windy and a tree branch had taken out one of the four exposed cables leading from the local transformer across the edge of the woods and one of our fields (which prevented the Tx from tripping out) and then welded two of the others together. Thankfully, because of the storm, I had unplugged most critical things around the house, but anything with a plug-in “wall wart” supply was toasted as well as anything that had a “brain” or logic board. I had also forgotten to unplug the UQ2 in my office. My heart sank when it wouldn’t power up. However, after replacing the inlet fuse with a new one it was fine - phew!
