I have a Worcester 24cdi combi boiler. Most of the time i can get hot water but sometimes (at least once a day) i cant get any. It happens more when i am in the shower, but if i run another tap slightly while the shower still runs the hot water kicks back in?
If someone could help would be really great full.
Thank you.

your flow switch diaphram has streched, your shower is not passing enough hot water to open it fully, by open another tap helps repalce diaphram
