hello martin the motor had new brushes fitted 2 mths ago the hose you mean is no more than 5mm thick and goes up to a circular pressure switch mounted above the drum
You will need to remove the rear half panel to fully access the water level system. Clean out the air chambers and their hoses, clean the sump hose and manifold too. That should sort it 😉
