The e24 error code on a Bosch dishwasher indicates a water drain issue. This can be caused by a clogged drain hose or a faulty drain pump. If the drain hose is clogged, it will need to be cleaned out. If the drain pump is faulty, it will need to be replaced.

1. Check the water supply and ensure that it is turned on and that there is adequate pressure

  1. Check the water supply to the dishwasher by turning off the main water valve to the house and verifying that the dishwasher is getting water from the main water line. If the dishwasher is not getting water from the main water line, the water supply to the dishwasher may be shut off.
  2. If the water supply is not the issue, then check the pressure in the dishwasher by using a pressure tester. If the pressure is low, then the dishwasher may need a new water pump.
