My Worcester 24i overheats everytime we run hot water, even if hot tap is opened for just a couple of seconds.
Run hot water - turn off - loud bangs - crackling / bubbling noise in pipes - reset switch pops up.
When this happens I generally run hot tap to release all remaining hot ( very ) water until runs cold - then press back down cut-off button - this will cause boiler then to ignite but as the boiler is now cold the noises come from the pipes and the boiler remains OK ( switch does not pop up ) and everything then settles down.
Central heating remains OK - no drop in pressure ( although needle jumps around during the loud banging ).
What's wrong and how much - thanks, anyone ?
