problems with mira shower going hot and cold

[charlie11]

I am having problems with my mira sport shower , it starts hot then goes cold and keeps on doing this, I have checked the filter which was a little dirty but made no difference. The shower head is clear and there seems plenty of power. I am not sure how to check the heating element, there are 4 electrical connections sticking out of the heater tank the nearest ones to the outside are linked with a plate, I believe these are the neutral side of the elements. I know it is long winded but I wanted to give as much information as possible. Thanks

Hi ya try taking the shower head off and running the shower sometimes the head gets scale in it and reduces the flow rate so the stat over heats because it doesnt go through the heat exchanger quick enough so the stat cuts in because its to hot and than the water turns cold than the heater starts up again and you get the same cycle boiling hot than cold.

Thanks for all the replies, I am going to bite the bullet and buy a new one.

Thanks again
