If your dishwasher is not cleaning your dishes properly, there could be a few underlying causes. Here are some possible solutions:
Clogged filter: Clean out or replace any filters which are clogged up with debris – this will help ensure that food particles and other grime do not prevent the water from reaching all of your dishes.
Low pressure: Check that the water pressure is sufficient – if it is too low then this can reduce the effectiveness of the cleaning cycle and leave spots on your dishes.
Incorrect detergent type: Ensure that you are using detergents designed specifically for dishwashers – tablets or powders optimized for machines will provide better results than hand-washing liquids which may leave residue behind after each cycle.
Wrong rinse cycle setting: Make sure to select the correct setting when running a cycle – some dishwashers require an additional rinse cycle for optimal cleaning, so check your instruction manual for more information about this.
