Electric shower only produces scolding hot or ice cold in hotter months. Any idea what I can do to fix this or is this normal?

If it's the usual isolator/service valve then it's a quarter-turn type. The 12-6 position is fully open (and the 3-9 position is fully closed).
It still seems like the problem is the flow rate either into or out of the shower unit. See these instructions about flow rate and maintenance.

If you can achieve the required input flow rate but not out then it would suggest that the stabiliser valve is is either blocked or faulty
