Bosch Dishwasher Error Codes Explained (E15, E24, E25 & More)
Bosch dishwashers are reliable, but when one flashes an error code it can be hard to know whether it's a quick fix or a service call.
Here's a plain-English guide to the most common Bosch codes and what to check before booking dishwasher repair.

The Most Common Bosch Codes
| Code | Usually means | First thing to check |
|---|---|---|
| E15 | Water in the base pan (leak protection tripped) | Tilt to drain the pan; find the leak source |
| E22 | Clogged filter / drainage problem | Clean the filter and sump |
| E24 | Drain blockage or kinked drain hose | Clear the filter, hose, and air gap |
| E25 | Drain pump blocked or pump cover loose | Check the pump impeller and cover |
| E09 | Heating element issue | Call for service |
Codes vary slightly by model — always check your manual.
E15: Water in the Base
E15 means the anti-leak float in the base pan has detected water. The dishwasher stops draining to protect your floor. Sometimes tilting the unit back to drain the pan clears it — but the real task is finding why water reached the base. A persistent E15 needs a technician to trace the leak.
E22, E24, E25: Drainage Problems
This family of codes almost always points to drainage. Start with the filter at the bottom of the tub, then the drain hose under the sink, the air gap by the faucet, and the drain pump. Our dishwasher not draining guide walks through each step in detail.
Before you call
Clean the filter and check the air gap — a surprising number of E22/E24 codes clear after a five-minute filter cleaning.

When to Call a Professional
- An E15 that returns after draining the base pan (there's a leak to find).
- A drainage code that persists after cleaning the filter, hose, and air gap.
- Any heating, control-board, or electrical code.
- Visible leaks from the door or underneath.
