Hello All
I have a worcester zwb 7-30 greenstart bioler which when you run the bath or shower at a high flow rate the boiler cuts out and displays the code E9. I can retset the boiler by pressing the reset button which clears the fault and is ok again unless you try to open the bath tap again fully. The manual appears to indicate that it is a fault with the CH flow safety temp limiter, can anyone offer any advice. Many thanks
