Diverter valve

[Matty A]

Just a quicky
The other day my inlaws had no hot water so they called someone in who told them it was the diverter valve that needed replacing.They got a quote for £190 inc new valve they said it was gonna take 2 hours at £60 an hour and the part was £70 so i went to the plumbers merchants where i get my gear from and got a valve for £35 and i have changed it myself.
Now the problem i have is i drained the system and changed the valves over,i put the new valve in the exact way the old one came out ie Port A to Port A and Port B to Port B and i wired it in the same as the wires on both valves were both the same.

I have filled the system back up and bled the rads but the pump from the boiler is constantly running is there owt i can do?

Cheers

Not sure if it's air but if you have a hot water cylinder there will be a bleed valve next to it on a vertical pipe coming from the heating pipe work!
