Possibly, however it's normally a single element that fails leaving your shower luke warm rather than stone cold. More likely a microswitch and check that power is still going to the shower via the double pole switch. If you do need any parts or a repair best try Mira Customer Service on 0844 5715000 who can sort you out for a fixed price.
