Bosch dishwashers are covered by a limited warranty. If any part of the dishwasher is defective, Bosch will replace it free of charge during the first year of ownership. Replacement parts are free during the second year, but the owner must pay the cost of labour. If the dishwasher fails to drain properly, troubleshoot it before contacting Bosch to obtain warranty service. Common issues that prevent the dishwasher from draining are often resolved through troubleshooting.

  1. 1

    Close the dishwasher door and allow the current cycle to complete. The dishwasher will not drain completely until the cycle is complete.

  2. 2

    Remove the screws securing the lower kickplate panel with a screwdriver. Remove the kickplate. Pinch the hose clamp with a pair of pliers and slide the clamp up. Disconnect the hose. Remove clogs by placing a garden hose in the end of the hose and turning the water on at full pressure. Reconnect the hose and secure it with the hose clamp. Replace the kickplate.

  3. 3

    Remove kinks in the drain hose. Ensure the hose is not kinked or pinched. Kinks prevent proper draining.

  4. 4

    Unplug the dishwasher or turn off the breaker or fuse for the dishwasher. Pull the bottom rack out of the dishwasher to access the waste water pump in the bottom of the tub. Remove the filter and remove standing water with a sponge. Use a spoon to dislodge the pump cover. Pull it up and then forward to remove it. Look inside the inner compartment. Remove objects that have fallen into the pump. Push down on the cover to reinstall it. Replace the filter and the bottom rack.

  5. 5

    Remove clogs in the plumbing system. Turn on the garbage disposal to empty it if the dishwasher drains into a disposal. If the dishwasher drains into a sink, pour liquid drain cleaner down the drain to remove clogs. Call a plumber if you are unable to clear the clogs.
