The top spray arm will be most likely blocked with some food particle that has got past the filter. If you pull out the top basket and remove the top spary arm.The spray arm is retained with a small screw, remove this and cleafully easy back the four plastic clips The arm shouldn now become free. Then wash out under the tap, when then spray slots are allowing water to pass freely refit the spray arm. Happy new year Steve
