It's only a couple of years old though... It has a phased shutdown employed. It couldn't be the phased shutdown relay? Is the flow switch the same thing?
Hi , yes, was thinking of the previous model .most likely the phased shutdown relay ,cost around £20.
Actually just checked and shower doctor do it for £12.88
Hi , will confirm with creda engineer , but he won't be back till 12 .
Hi spoke to creda guy . he has said. That it will be the Redding microswitch ( pressure ) but it can be very difficult to change as the unit it is in tends to pop part when changing it . this is the part.
For the price of the switch its worth having a go .
