This question is regarding Mira Sport Max - Shower Spares

Takes several attempts to heat up

Shower sometimes has to be switched on and off several times before it will heat the water. Sometimes when it is switched on you will hear a slight buzzing sound and know that the water will be cold. I've changed the thermal switch but it hasn't made any difference. At other times it works fine!

There could be a problem with the PCB which is intermittent , but check the connections inside the shower are sound with no loose connections as well.
