      Tracy PhelpsAug 30, 2025
      If water remains in your Bosch dishwasher after a cycle, the waste water hose might be blocked or kinked. Alternatively, the waste water pump could be blocked, or its cover might not be locked in position. It's also possible that the program hasn't finished yet; wait until the digital display indicates completion or use the reset function.
