Shower constantly running

[jcr1987]

I posted before about this but forgot all about it so have put it on again. Also put the wrong info in the last message, apologies kevplumb.

My shower is an Aquatronic 3, which won't switch off even when it is turned off at the power switch. It is literally running as fast as when it is turned on.

Any suggestions?

Not sure whats in side those but i 'd guess if it has an inlet soliniod valve on the cold water main it must be jamed open. Not all showers have these but most do, when the powers of they are shut normally. u can replace them but with electric showers its some times easier & more cost effective to change the whole unit depending on its age,
