Bosch made its name on quiet, efficient dishwashers, and the same engineering runs through its ovens and cooktops. The upside for repair is that Bosch reports faults clearly with E-codes, so a good diagnosis starts by reading the machine rather than guessing. The trap is treating the code as the whole answer: an E15 tells you water reached the base pan, but not where it came from. We find the source, not just the symptom.
Models We Service
- Dishwashers: Benchmark, 800, 500 and 300 series, including fully integrated panel-ready models with CrystalDry and the third rack.
- Wall ovens: Benchmark and 800 series single and double ovens.
- Cooktops: Benchmark and 800 series induction and gas cooktops.
- Refrigeration: Bosch built-in and counter-depth refrigerators.
- Ranges: Bosch induction and gas slide-in ranges.
Error and Fault Codes
Bosch E-codes are genuinely helpful, and these are the ones we see most on the dishwashers. Meanings are consistent across the BSH platform, though the exact remedy can vary by model, so we verify before replacing a part.
| Code | Commonly Indicates | What We Do |
|---|---|---|
E15 | Water in the base pan; anti-flood float tripped | Find the leak, drain the base pan, repair the source |
E22 | Filter or drainage blockage | Clean the filter and sump; clear the drain path |
E24 | Drainage fault: not pumping out | Clear the hose and filter; test the drain pump |
E09 | Heating element or its circuit | Test and replace the flow-through heater |
| Oven sensor fault | Open or shorted oven temperature sensor | Measure and replace the sensor |
Our blog covers the two most common calls: the E15 error and the E24 error.
E15 Is the Anti-Flood System Doing Its Job
When a Bosch shows E15 and will not run, a float in the base pan has detected water and shut the machine down to protect your floor. Tilting the machine to drain the pan clears the code, but if you skip finding the leak, it comes right back. The leak is the repair.
Common Problems We Fix
- Dishwashers stuck on E15 from a base-pan leak.
- Dishwashers that will not drain, showing E22 or E24.
- Cold washes and poor drying from an E09 heater fault.
- Poor cleaning from spray-arm, filter and pump issues.
- Ovens that will not heat or hold temperature.
- Induction cooktop zones that will not power a pan.
Maintenance and Guides
Most E15 and drainage faults are preventable with routine care. Our Bosch dishwasher maintenance guide covers filter cleaning and leak prevention, and our water leaking page explains how base-pan leaks develop.

Frequently Asked Questions
What Does the Bosch E15 Error Mean?
E15 means the anti-flood system has detected water in the base pan, which trips a float and shuts the machine down. It is protecting your floor. The fix is to find and stop the leak, then drain the base pan, rather than simply clearing the code, which will only return.
What Does the Bosch E24 Error Mean?
E24 is a drainage fault: the machine cannot pump water out fast enough. The usual causes are a clogged filter, a blocked or kinked drain hose, or debris in the pump. Cleaning the filter and clearing the drain path resolves many E24 faults.
What Does E22 Mean on a Bosch Dishwasher?
E22 points to the filter or drainage, typically a dirty filter or blocked sump that stops water from draining properly. It often appears alongside poor cleaning results, and cleaning the filter is the first step.
What Does the Bosch E09 Error Mean?
E09 indicates a problem with the heating element or its circuit, so the water is not being heated for the wash or dry. It usually means the flow-through heater has failed and needs replacement.
Do You Repair Bosch Ovens and Cooktops Too?
Yes. Alongside the dishwashers we service Bosch Benchmark and 800 series wall ovens, induction and gas cooktops, and refrigeration, so a Bosch-equipped kitchen can be handled together.
Do You Use Model-Specific Genuine OEM Parts?
Yes. We source OEM pumps, heaters, valves and control boards by model, which matters on the flow-through heater and electronic controls Bosch uses.
