Mira Magna issue

[awmech]

For the last few months I’ve had an issue with my Mira Magna digital mixer, which has a pump and is on a gravity fed system.
I work away from home and lately when I get home again, after a week or more, the shower doesn’t power up when switched on at the wall switch, no blue light on the controller and no sound (it shears makes a quick sound like the pump priming or something when it is switched on at the wall)
Eventually, after quite a few attempts and maybe after a day or so, it will come back to life and works fine every day until it’s left for a week or so again.
Any ideas what this could be, PCB?
TIA

Pull switch in bathroom to power? Check that's good and tight screws.
Sounds intermittent fault vs actual fault with electronics.

Mira have a repair service which is about £100

I did think about checking the wall switch but it also powers the extract fan which works every time

Fan don't pull so much power so won't show same symptoms. Shower pulls loads and if it's not making good contact it can get black and hot. Be intermittent with connection.
If you can check the connections are good and look fine.
