@Jojoe sadly the image just shows the maximum fuse size up to 415V the fuse carrier is rated at and does not dictate the acual fuse size inside.
I’m surprised the DNO didn’t put their sticker over stating the actual fue size, when they last visited. However, I would safely say, the DNO upgraded it to a minimum of 80A when your washer/tumble dryer blew it.
Do you know who your DNO is? You can either call them and ask them to ceck what size cut-out fuse you have, as ?Ohme have recently fitted a EV charger (You don’t need to say any more), the DNO will either check on their system or send somebody out for free to calarify the size. You can then contacy Ohme and tell them to upgrade the the Max load limit, to match whatever fuse size you have.
Or, Contact Ohme in the first place and ask them to upgrade the load limit to 80A or to match the cut-out. Ohme would have contacted the DNO prior to installing the charger and arranged a upgrade if it was 60A
National Grid (Western Power) fit a maximimum of 80A and so do Northern power and alot of other DNO’s.
See how you go on with that, rather than looking to deeply in matters yet.
