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.
The bottom line on the E24 error
E24 is a drain fault, and nine times out of ten the culprit is a clogged filter or a kinked drain hose, not a dead pump. Resetting the machine just hides the problem โ the water still will not drain until you physically clear the blockage.
Start cheap: pull and rinse the drain filter, then check the hose and disposal connection before spending a cent. Cleaning fixes most cases for free; only a truly failed drain pump ($50โ$150) needs a part, still far cheaper than replacing an under-eight-year-old machine.
E24 snapshot
Water plus electricity โ always unplug the dishwasher and shut off the water supply before pulling the unit out or reaching into the drain pump.
Our own at-a-glance triage of the E24 error, from the verified data on this page. See error-code rankings โ ยท How we score โ
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.
Which Bosch dishwashers get the E24 error
E24 shows up across most modern Bosch dishwashers with electronic diagnostics โ the 100, 300, 500, 800, and Benchmark series built roughly from the mid-2010s onward, including popular SHPM, SHEM, SHXM, and SGV model prefixes. Because it's a filter/drain code rather than a model defect, it can appear on a nearly new unit just as easily as a 10-year-old one.
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.
๐งฐ 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.

Repair or replace?
In the large majority of E24 cases there is nothing to buy โ a clogged filter or drain hose is a free fix, so always try cleaning before spending a dime. If the drain pump itself has failed, a $50โ$150 part plus install is still far cheaper than a new dishwasher ($500โ$1,200+) and well worth doing on a unit under about 8 years old. Only consider replacing the whole machine if it's older than 10 years and stacking up other faults, using the rule of thumb that a repair costing more than half the price of a new unit isn't worth it.
Common replacement parts for the E24 error
| Drain pump | $50โ$150 | Only needed if cleaning doesn't clear the code | |
| Drain hose | $15โ$40 | If kinked, cracked, or clogged beyond cleaning | |
| Filter assembly | $20โ$50 | Rarely needed โ usually just rinse the existing one |
Prices are typical retail ranges and vary by model and supplier โ always confirm the exact part number for your appliance before buying. We are not linking parts for this code on purpose: it is a job for a qualified technician, and the right fix here starts with a diagnosis, not a purchase.
Bosch E24 error โ FAQ
๏ผ โ 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.
๏ผ โ 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.
๏ผ โ 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.
