This testing protocol helps diagnose a dishwasher that has a water drainage problem by checking the operation of the drain pump and the pressure switch.

  Before starting the dishwasher, pour a large glass of vinegar into the tub. Wait 5 minutes before starting the appliance.
  
  To begin its cycle, the appliance will first try to pump out any water remaining from a previous use.
  
  If you do not hear the pump engage and a water intake occurs immediately, the pressure switch is likely faulty.
