electric shower not heating water

[turnitup]

my step mother has a electric shower but it's running cold she's had three plumbers out and not one has solved the issue.

does any person have any clue what could be wrong? maybe the heating element?

What did the other plumbers do ? advise?

unless its a really decent shower like a mira or such like it would easier and quicker to just get a new one.
