Mira orbis

[tdz840]

Hopefully someone can help or provide advice.
I have mira orbis 10.8KW shower.
I had a problem where the shower would only run cold.
I identified an issue with the one shot thermal switch which was replaced nf cured the problem.
For about two weeks then the switch failed again.
Symptoms were shower started and operated ok, when the shower was turned off the water turned cold then spluttered and appeared to be steam coming out of the shower head.
I replaced the TCO but after two weeks approx the same issue.
I have a pare TCO but don't want to keep replacing switches without getting to the root cause.
Looking through previous peeps problems the issue may be the control board but I don't want to be buying components and replace and not identify the problem.
Can anyone offer advice or checks I could do to identify the issue?
The shower is about 12 months old and used every day
Thanks in advance
Russ

to be honest
I don`t fix showers
for the price of them it easier just to replace it

I would agree if I had to factor in a plumbers call out.
However I feel the issue is either a replacement heater can(£120) or a control board(£70)
I was hoping to save the cost of a new Mira Orbis 10.8KW (circa £400) as a change to cheaper shower may involve additional plumbing/wiring/tiling.
Clearly buying a control board at £55 is my preferred option, however if it turns out to be a heater can, control relay or other component then it starts getting pricey and replacement worthwhile.
I note there has been a control board issue on this forum and just wondered if this was a common fault.
This shower is only a year old and can't believe the heater can has already furred up?
I was hoping for some pointers or checks I could make to isolate the issue.
