How to Fix Error E25 — Step by Step

  1. 1

    Reset and Power Cycle

    Begin by unplugging the dishwasher from the power outlet and waiting for 30 seconds. This will reset the appliance's electronic controls. Next, plug the dishwasher back in and press the 'Start' button to initiate a power cycle. This will help clear any temporary faults that may be causing the error code. Wait for the power cycle to complete before proceeding.

    💡 Pro Tip: Make sure to unplug the dishwasher before starting the power cycle to avoid any electrical shocks or injuries.

  2. 2

    Check the Drain Pump Impeller

    Locate the drain pump impeller, which is usually located at the bottom of the dishwasher. Remove the lower panel by using a Phillips #2 screwdriver to remove the screws. Once the panel is removed, inspect the drain pump impeller for any blockages or debris. Use a Torx T20 screwdriver to remove any screws holding the impeller in place. Gently pull the impeller out and inspect it for any signs of damage or blockage.

    💡 Pro Tip: Be careful when handling the drain pump impeller, as it may be fragile and prone to damage.

  3. 3

    Clear Blockages

    If the drain pump impeller is blocked, use a drain snake to clear any debris or blockages. Insert the drain snake into the drain hose and rotate it slowly to clear any obstructions. If the blockage is severe, you may need to use a more powerful cleaning tool, such as a drain auger.

    💡 Pro Tip: Make sure to wear gloves and safety goggles when using a drain snake or other cleaning tools to avoid any injuries.

  4. 4

    Inspect and Clean the Drain Hose

    Inspect the drain hose for any kinks, twists, or blockages. Use a multimeter to check the hose for any signs of damage or corrosion. If the hose is damaged, replace it with a new one. Clean the drain hose by running hot water through it and using a soft-bristled brush to remove any debris or blockages.

    💡 Pro Tip: Make sure to check the drain hose for any signs of damage or corrosion, as a damaged hose can cause the dishwasher to leak or overflow.

  5. 5

    Replace the Drain Pump Impeller

    If the drain pump impeller is damaged or blocked beyond repair, replace it with a new one. Make sure to purchase a genuine Bosch part or a high-quality aftermarket replacement. Follow the manufacturer's instructions for installation and replacement.

    💡 Pro Tip: Make sure to properly dispose of the old drain pump impeller and any packaging materials.
