Bosch Dishwasher Not Draining? Here’s What You Need to Know

Bosch dishwasher are known for their efficiency and quiet operation, making them a popular choice in many homes. However, like any appliance, they can encounter issues — one of the most common problems is when the dishwasher won’t drain properly. If your Bosch dishwasher is not draining, it can lead to standing water, unpleasant odors, and poor cleaning performance. Luckily, many causes are straightforward to diagnose and fix.

Common Causes of a Bosch Dishwasher Not Draining

  1. Clogged Drain Filter or Drain Hose
    Over time, food particles, grease, and debris can build up and block the dishwasher’s drain filter or hose. This blockage prevents water from exiting the dishwasher and can cause water to pool at the bottom.

  2. Faulty Drain Pump
    The drain pump is responsible for pushing the water out during the draining cycle. If the pump motor fails or becomes clogged, the dishwasher won’t drain properly.

  3. Garbage Disposal Connection Issues
    If your dishwasher drains through a garbage disposal, a clog or blockage in the disposal can prevent proper drainage. Also, if the knockout plug in the disposal inlet wasn’t removed when the dishwasher was installed, water won’t drain correctly.

  4. Kinked or Damaged Drain Hose
    Sometimes the drain hose can get kinked, pinched, or damaged, restricting water flow and preventing draining.

  5. Malfunctioning Check Valve
    The check valve prevents water from flowing back into the dishwasher after draining. If it’s stuck or broken, water may remain inside the dishwasher.
