Where E15 is a leak safety, E24 is a drainage complaint. The dishwasher tried to pump the water out, the flow was too restricted, and it halted the cycle rather than sit full. That makes E24 one of the more owner-friendly Bosch faults, because the restriction is usually in the filter, the hose, or the pump, all of which are checkable from the tub or the sink cabinet.
What E24 Is Telling You
E24 means the drain did not complete in the expected time. The pump is running or trying to, but water is not clearing. The restriction is somewhere between the sump at the bottom of the tub and the household drain. Work that path in order and you will find it.
Clearing the Drain Path
Turn the machine off and remove the filter assembly at the bottom, rinsing it and clearing the sump and the visible pump area of food and glass debris. Then check the drain hose at the sink or disposer for a kink or clog. Reseat everything and run a short cycle to confirm it drains fully.
| Cause | How It Shows | Our Fix |
|---|---|---|
| Clogged filter or sump | E24, water in tub | Clean filter and sump |
| Kinked or blocked hose | Slow or no drain | Clear or re-route hose |
| Debris in drain pump | E24 after cleaning filter | Clear or replace pump |
| Disposer knockout plug | New install, no drain | Remove knockout plug |
Prevent repeats: clean the filter regularly and scrape plates before loading. Most E24 faults are a filter that quietly clogged over months.
What You Can Try, and Where to Stop
Cleaning the filter, sump, and hose is safe and resolves most E24 faults. If it returns after that, the drain pump is obstructed or failing, and servicing or replacing it is a technician job that carries a warranty on the repair.
E24 Will Not Clear?
Book a Bosch specialist to service the pump. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
Frequently Asked Questions
What Does E24 Mean on a Bosch Dishwasher?
E24 is a drainage fault. The dishwasher tried to pump water out and the flow was restricted, so the cycle stops with water in the tub. The usual causes are a clogged filter, a kinked or blocked drain hose, or a drain pump obstructed by debris. It differs from E15, which is a base-tray leak.
How Do I Fix a Bosch E24 Error Myself?
Turn the dishwasher off, remove and rinse the filter at the bottom, and clear any debris in the sump and pump area. Check the drain hose for a kink at the sink connection. Reseat everything and run a short cycle. If E24 returns, the drain pump likely needs testing.
What Is the Difference Between Bosch E24 and E25?
Both are drainage faults. E24 typically indicates a general drain restriction such as a clogged filter or hose, while E25 more specifically points at the drain pump being blocked or the pump cover not seated. In practice both are cleared by clearing the drain path and, if needed, servicing the pump.
