Help with a Shower fault please

[Wilk]

My shower has suddenly started running cold on its usual flow setting. The only way that I can get the water warm is to turn down the flow to a really low level which gives an awful shower.
I am an electrician but have never done any shower testing/repairs before so I would really appreciate any suggestions/help with tests and meter readings that I can perform to identify the fault.
I would really appreciate any help that you can give.
Thank you

low water pressure or a dying shower unit. poss. due to build up of calcium carbonate inside.

Knackered heating element i reckon.Unable to heat the higher flow of water

either way, looks like a trip to Bodge&Quit

 

[Amp David]

Oh yes!

Thank you for your help guys.
Do you not think that it is worth identifying the fault and replacing that part?
