The answer you came for

How to fix Bosch dryer error E23

Start with the safest checks and work from simple to technical.

  1. 1

    Step 1

    1. Disconnect power. Unplug the dryer from the wall outlet to ensure safety.

  2. 2

    Step 2

    2. Access the base of the dryer. You may need to remove a lower front access panel or carefully tilt the machine back to see the bottom pan.

  3. 3

    Step 3

    3. Check for water in the base pan. The E23 code is often triggered by a float switch when water leaks into the bottom of the machine. If water is present, soak it up completely with towels and find the source of the leak, such as a loose hose or a crack in the drain pump housing.

  4. 4

    Step 4

    4. Locate and inspect the anti-flood float switch. It is usually a styrofoam disc in the base pan that rises with water to activate a small switch. Ensure the styrofoam is not stuck in the 'up' position and that the switch clicks when moved by hand.

  5. 5

    Step 5

    5. Inspect the drain pump and hoses. Locate the small pump at the bottom of the dryer that removes condensed water. Disconnect the hoses attached to it (place a towel underneath to catch any remaining water) and check both the hoses and the pump inlet/outlet for lint clogs or debris.

  6. 6

    Step 6

    6. If no leak or clog is found, the issue may be the main control module. This part is the electronic brain of the dryer, typically located behind the main control panel.

  7. 7

    Step 7

    7. To replace the control module, remove the top panel of the dryer. Take a clear photo of all wire connections to the module before disconnecting them. Carefully unclip or unscrew the old module, install the new one, and reconnect all wires exactly as they were in your photo.

What to Check Next on This Bosch Dryer Use these checks before ordering parts for Bosch dryer E23. They keep the diagnosis tied to the appliance instead of turning the page into a reset-only guide. Unplug the dryer before touching the lint housing, rear vent, lower service area, or any wiring. Clean the lint screen, moisture sensor bars, condenser area if equipped, and the full vent path so airflow problems do not imitate part failures. Run a short timed cycle with a light load and note whether the fault appears immediately, after heating starts, or near the end of the cycle. If the fault returns with clean airflow, inspect the part categories below using the full model number from the dryer tag. Stop repeated test cycles if you smell heat, see moisture near electrical areas, or hear grinding from the drum drive. Verified Compatible Alternatives:0066122900631326481590 Still Not Working?
