Just got off the phone with Hager technical who said they'd "never heard of the fault I was describing and couldn't help". He didn't even suggest buy a replacement!
The story goes...
While testing an old split-load board, the RCCB stopped working. It's a 63A, 30mA one and the board was made in 12/99 - there's no labels or paperwork to say when it was fitted.
Firstly I pressed the Test button and it functioned correctly.
Secondly I plugged my Fluke 1653 into a socket circuit supplied from the RCCB and set the RCD time tests to Auto. This gave satisfactory results at 1/2x, 1x and 5x with the RCCB being reset just fine after each.
Finally I did the ramp test to see what current it was tripping at and got Err4 on 0 degrees, so decided to do it again and got 24mA.
I then did the ramp test again but at 180 degrees as I often find differing results. However, I went to the RCCB to reset it and although the dolly moved, no power went through. The Test button no longer functioned either.
Anybody else had this kind of experience?
Hager Tech did also say that ramp testing isn't a required test and so I probably shouldn't have done it. Maybe the ramp test broke the RCCB?
When I have a remedy I'll update this. My thoughts are to double check the wiring and then fit a replacement if still no joy.
