I had put my Bosh logixx 8 on a cotton stain cylcle, 10-15 mins into the programme I paused it to add x2 sml items , it then started flashing F18. What is it telling me as I do not have the booklet to hand.
F18 = Drain pipe clogged. Drain machine using the little pipe bottom right (panel comes off). Then unscrew white knob & clean rotor. Check rear hose too.
