Put some water in bowl then advance to final spin & press start. Check flow rate of water from end of drain hose. If weak flow then either pump is running too slow or there is a blockage. If flow is fast then pump & hose is okay. Then check air pressure tube inside panel on right hand side. Take it off the controller & blow down it to remove any blockage. If fault still exists after that then it is probably a faulty control board.
