The machine is unable to drain the water in the expected time. The usual cause is the filter is blocked.
Remove a white circular cover on front bottom right, turn it anticlockwise using a large coin or sturdy flat screwdriver.
Unscrew the black filter, again anticlockwise about 3 revolutions. About one litre of water will come out, be ready to mop it up. Remove the filter, dislodge all disgusting material (usually buttons, hairs, strands of cloth, bits of soil, coins).
Re-fit filter, replace cover, try again.
