heatslave 9.24 leaking

[claratsi]

Looking for help with a worcester heatslave 9.24.

simple question really. i think/hope!

connected to the diverter/flow switch is the 3/4 pipe going to the heat exchanger.

The joint connecting the 3/4 pipe from the heat exchanger to the diverter is leaking. is it safe to undo this joint after draining the system and reseal or is the heat exchanger a factory sealed unit?

Thanks,

Drain Heating and hotwater circuits, undo nut, there is a fibre washer between the pipe and the brass diverter body, fit a new washer and replace the nut, (don't overtighten!)

Refill both ccts and test

IT may be easier to do if you take the side off to do it.
