No hot water & Heating working intermittently ?

[Bartman]

Got a Baxi Bahama combi and this morning got no hot water. When turning on tap the boiler seems to turn off and when turning them off the boiler seems to start up again.
The other day the heating was taking a lifetime to get working but the hot water was working ok. Are the two linked together by chance?

hi bartman it sounds as if ur pump has seized or even failed u can try loosening it by tapping it gently with a hammer or even replacing it but other than that ur system may need flushing
