Turn the spray arm by hand

ReversibleSpin each arm by hand to make sure that it turns freely, and that no dish, cup or utensil is touching it.
Clean the filter and the arm holes
ReversibleRemove the filter, rinse it and look into the holes of the spray arms for food or scale that restricts the water.
Start the cycle again
