Bosch Dishwasher E24 Error
What it means
E24 means your Bosch dishwasher cannot drain the dirty water out of the tub. It almost always points to a blocked drain filter, a clogged drain pump, or a kinked or obstructed drain hose. You will usually find standing water in the bottom of the dishwasher after the cycle ends.
Common causes of the E24 error
- A clogged drain filter at the bottom of the tub (the most common cause) packed with food debris, grease, or bits of glass.
- Debris caught in the drain pump or impeller, preventing it from pushing water out.
- A kinked, crushed, or clogged drain hose between the dishwasher and the sink drain.
- A new garbage disposal whose knockout plug was never removed, blocking the dishwasher drain line.
- The drain hose is mounted too low or not high enough (no high loop), causing water to siphon back.
How to fix the Bosch Dishwasher E24 error
- 1Power down and run a quick resetTurn the dishwasher off and unplug it (or switch off its breaker) for about 5 minutes, then restore power. A short reset sometimes clears a one-time fault. If E24 returns, continue with the steps below.
- 2Clean the drain filterOpen the door, pull out the lower rack, and twist out the cylindrical filter assembly at the bottom of the tub. Rinse it under warm running water with a soft brush to remove trapped food, grease, and grit. Also wipe out the sump area underneath where the filter sits.
- 3Check the drain pump for blockagesWith the filter removed, look into the sump and the pump opening for foreign objects such as glass shards, seeds, or labels. Wearing gloves, gently clear anything you find and confirm the pump impeller can spin freely. Reseat the filter firmly when done.
- 4Inspect the drain hose and disposal connectionMake sure the drain hose is not kinked or crushed behind the unit and that it forms a high loop under the counter. If you recently installed a garbage disposal, confirm the knockout plug inside the disposal's dishwasher inlet was removed, as it will block draining if left in place.
🧰 When to call a professional
If the filter, pump, and hose are all clear but E24 keeps coming back, the drain pump motor or the control board may be faulty. Replacing a pump involves disconnecting water and power and accessing the base of the unit, so call a Bosch-authorized technician (or Bosch support at 1-800-944-2904) if you are not comfortable with that work.
Bosch E24 error — FAQ
Can I keep using my dishwasher with the E24 error?
No. E24 means the dirty water is not draining, so dishes will not get clean and water can sit in the tub and turn foul. Clear the blockage before running another cycle.
How do I reset a Bosch dishwasher after fixing E24?
After clearing the blockage, press and hold the Start button for about 3-5 seconds to cancel and drain any remaining cycle, then run a short rinse or normal cycle to confirm the water drains fully and the code stays gone.
How often should I clean the filter to prevent E24?
Rinse the filter every couple of weeks if you wash heavily soiled dishes, or at least once a month for light use. Scraping food off plates before loading also keeps the filter and pump clear.
