Hi Geoff it doesn’t have a filter as such. There is a sump hose to pump that has a catch pot. Coins buttons etc fall in but the pump is self cleaning. If it’s leaking only on spin it might be a small hole in middle or top creases of door seal. Or soap
Powder drawer to run hose ( ie water flung up will spray out somewhere it’s wouldn’t drip out under gravity. Prob best to unplug and take top and back off and see where is wet and same underneath.
Good luck
Richard
This photo is of earlier logic yours will have a pressure hose connection on ( which sometimes clogs with grease - and stops the machine spinning )
