Water Softner, over flow prob

[Starship1]

Hi all;
I have a WaterSide water softner fitted along side my combi boiler which has been working fine, but just of late the over flow is constantly dripping, I have repressurised the boiler, performed a recharge, re-sets, but it continues to drip, not just the occasional drip, quite a bit more.
Any ideas please.
Regards..
