I see. They look open to me. Plus I've never closed them.

Did you check and make sure the system has enough water in it before you rip anything out or a fill valve needs to be turned on system might be just going dry not enough water in it and the boiler will keep going to lock out

Just call your local plumber in I,d say it just needs to be filled and tested maybe a bit of balancing to be done nothing major get to have a look at the old leak on the trv pipework as well I recommend

Whoever wired the pump didn't do a very good job. Might be worth unplugging and checking the connections are tight.

What speed is the pump on? If it's on Autoadapt, try each of the fixed speeds in turn to see what effect it has.

How do o check what speed the pump is on?

This pic shows it's on Autoadapt.

Page 12 of the attached pdf (below pic) tells you how to change the speed setting. It also explains what the "--" lights mean.
