Bosch reports faults through numeric codes on the display. Knowing what a code points to helps you decide how urgent it is and what to expect from a repair. Here are the Bosch codes we see most often in Sandy Springs.
Bosch Codes at a Glance
| Code | What It Means | How We Fix It |
|---|---|---|
| E15 | Base pan leak, anti-flood tripped | Find and dry the leak, reset the float switch |
| E24 | Drain fault, water not pumping out | Clear the filter and drain hose, test the drain pump |
| E22 | Filter or drainage blockage | Clean the filter and check-valve, verify drainage |
| E09 | Heating element fault | Test the flow-through heater and its wiring |
What the Codes Have in Common
Most Bosch codes point at a single circuit, usually one of the sensors, heaters, valves, pumps, and motors or the control board behind it. A code is a starting point, not a verdict: the same number can have more than one cause, so we test the flagged circuit directly.
How to Respond to a Bosch Code
Copy the Bosch code down first, then power-cycle the appliance. If the code stays gone it was a one-off; if it returns or the appliance stays locked, a part has failed, and pushing more cycles through it to clear the code can escalate the problem.
What a Bosch Repair Involves
Our diagnosis starts at the code but does not stop there. We measure the flagged part, one of the sensors, heaters, valves, pumps, and motors, against its specification, confirm the real failure, and check that a second fault is not hiding behind the first. Then we fit a model-specific Bosch component and rerun the 300, 500, 800, and Benchmark dishwashers-class unit to confirm the code is gone.
When to Call
If a code returns after you clear it, or the appliance stops working, book service. We read the exact code, test that circuit, and fit a model-specific part backed by written warranty terms for eligible completed repairs.

Frequently Asked Questions
What Causes Bosch E22?
E22 flags a filter or drainage blockage. We clean the filter and check-valve and confirm the unit drains fully before closing the repair.
What Does Bosch E09 Mean?
E09 points to the flow-through heating element. When the dishwasher will not heat the wash water, we test the heater and its wiring and replace the failed part.
Why Won't My Bosch Dishwasher Dry?
Bosch relies on condensation drying and a rinse-aid boost. Poor drying can trace to the heating element, a rinse-aid dispenser fault, or loading. We test the heat circuit and dispenser.
