Hi,
Worcester 28i Junior Combi Boiler
The hot water lasts only probably 2 or 3 minutes and then become cold for about 30 seconds then warm/ hot again... thought it's the limescale blocks the secondary heat exchanger.
Now the plate heat exchanger has been replaced but the problem still exist!
Could be the diverter valve scaled too? Or any idea?
Thanks
