Earth wiring doubt replacing classic British Fused Spur with Timeguard Wi-Fi Fused Spur

[ProDave]

I would really work on tidying up those L and N wires, wrapped wires like that exposed are not up to standard.  Do as you did with the earths, cut the mangled ends off, strip a fresh bit nice and straight and see if you can get them fully into the terminals with minimal twisting. But you might find the terminals are not large enough.

FWIW I don’t think that turning on the socket will start the dishwasher...

It does turn on. I have the dishwasher running right now and the app is working well BTW. The problem with this Timeguard unit is the electrical noise I can hear.

I will very likely try to do what you say in a few days/weeks once I change the unit for one that does not make that electrical noise. I will try to find out if I have been unlucky with the unit or all of them has this problem. In the later case I will maybe reinstall the old switch and use a FIBARO Relay Switch (or similar) behind the socket or maybe I will just put a Switchbot over the old switch.

RE the noise, call Timeguard technical and see what they say

Have you tried loosening the fixing screws, it may be that the size of cables behind it are pushing on the back plate causing a vibration or worse?

In order to check if that was the problem and just for this test, I unscrewed it and moved it out of the back-box placing it in a way that shouldn't vibrate. I switched on everything again and the noise was the same. I suppose it is a problem of the Timeguard fused spur switch. I will phone Timeguard's technical support as @Murdoch suggested.
