Not as if people choose to have a shower at below maximum flow rate.

Surely max flow rate is cool, I don’t like cool showers 🤷‍♂️

Well yes.

Should have said 'max flow for the temperature wanted'. 

Only weirdos like cold, dribbling showers, or maybe that is just my memory of the communal showers after rugby at the minor public school I went to.

It's my experience that thermal trips degrade with the increasing number of trip/reset cycles. It might've been on the bitter edge for years but now that it's tripped a few times it'll go a bit more easily.

 

I'd replace it with a 40A and ensure there's no evidence of heat damage on the cable ends, and re-try.
