Central Heating & Hot Water - problems

[budgie69]

Hi, hope somebody can help..

i only seem to have hot water when the central heating is on.
When the CH goes off, no hot water.

If i turn of the boiler from the electric socket and leave off for 15mins, everything is working again.

Problem comes back as soon as the heating is turned back on.

I have a combi worcester boiler model 24i Junior.

thanks for any advice anybody can give

Hi.....

Do you get a fault code on the boiler?? ie does the light flash 4 times per second or once a second??

thanks for your advice.

Ok, well if the hot water sensor was faulty the light would flash 4 times a second. There could be a fault on the circuit board,although this would most probably affect the central heating also. The fault is most likely to be the flow sensor, so the boiler is not recognising the flow of hot water, part costs about 25 quid
