Hello! DIY noob hear asking for advice on a leak from an air break.

My undersink plumbing is a mess of pipes handling washing machine, dishwasher, and boiler condensate.

When the washing machine runs, the air break overflows. The dishwasher is on too, the problem is worse. This used to happen intermittently, now more regularly, although the leak is small (half pint / 100ml). Reading around, I wonder if the discharge volume is at near capacity.

Could the undersink plumbing be part of the problem? I'd like to avoid having to dismantle the fitted kitchen to explore further down...

Any ideas gratefully accepted!
