Why does my Bailey autograph 765 alde heating system dump fluid from the overflow pipe I have to keep topping it up

I think you mean Alde heating. It sounds overfilled to me. The liquid expands in use and needs to be on the bottom line when cold.

How full are you filling it?

We were told just above the minimum mark when cold.

Also your pump should be set not higher than 3

Possible air lock...
