What should I do if my dishwasher displays 'F2'?

'F2' on the display indicates that either the filters or spray arms are dirty, the drain hose is kinked, there’s too little water in the system for washing, or too much foam has been produced due to incorrect detergent use. Clean and check the condition of the parts as described under 'Troubleshooting'. Adjustments like increasing rinse aid dosage may also be necessary.
