Bosch is the workhorse of the luxury kitchen, the quiet, panel-ready dishwasher that shows up next to a Sub-Zero and a Wolf because it simply gets the job done without drawing attention to itself. It is also, along with Thermador and Gaggenau, part of the BSH family, which means its E-series fault codes are well documented and its boards are familiar territory. The practical upshot for a homeowner in West Chester is that a Bosch fault is rarely a mystery: the machine tells you what is wrong, and a technician who reads those codes can go straight to the part. Our team is brand-focused on Bosch across dishwashers, ovens, and cooktops.
The dishwashers are where we spend most Bosch service time. The 800 Series and Benchmark units are everywhere in local kitchens, and an E15 or E24 on a full load is one of the calls we take most often.

- Wall Ovens: Benchmark and 800 Series single and double ovens.

Error & Fault Codes
Bosch dishwashers use a well-known E-series set. The ones we see most in West Chester kitchens:
| Code | Meaning | Our Fix |
|---|---|---|
| E15 | Water in base tray, AquaStop float tripped | Dry the base, find and repair the leak source |
| E24 | Drain restriction or failing drain pump | Clear hose and air gap, replace pump |
| E22 | Blocked filter or check valve | Clean filter and valve, verify drainage |
| E09 | Flow-through heating element fault | Test element, replace pump/heater assembly |
| F code on oven | Temperature sensor or relay | Test sensor, replace sensor or board |
Common Problems We Fix
- Dishwashers stopping on E15 with water in the base.
- E24 and E22 drainage faults leaving standing water.
- E09 heating faults leaving dishes cold and cloudy.
- Poor drying from rinse-aid or auto-open issues.
- Ovens throwing an F-code or refusing to heat.
- Induction cooktops that flash or cut out.

Frequently Asked Questions
What Does E15 Mean on a Bosch Dishwasher?
E15 means water has collected in the base tray and the AquaStop anti-flood float has switched off the machine to prevent a leak. It often clears after the water is dried out, but if it returns there is a model-specific leak, commonly from a hose, the sump, or a cracked component. We find and fix the source rather than just resetting it.
What Is the Difference Between E24 and E22 on a Bosch Dishwasher?
Both involve drainage. E22 points to a blocked filter or a fouled check valve so water is not clearing the tub, while E24 points to a restricted drain hose, air gap, or a failing drain pump. We clean the filter and check the full drain path, then test the pump.
What Does E09 Mean?
E09 indicates a fault in the flow-through heating element that warms the wash water. When it fails, dishes come out cold and poorly cleaned. The element is integrated with the pump housing on many Bosch models, so we confirm the fault and replace the correct assembly.
Why Is My Bosch Dishwasher Not Drying?
Bosch uses condensation drying and, on higher models, a zeolite mineral and the AutoAir door that pops open at the end. Poor drying often comes from low rinse aid, a disabled auto-open, or plastic loads that hold water. We check those before assuming a component has failed.
Do You Service Bosch Ovens and Cooktops Too?
Yes. We repair Bosch wall ovens, ranges, induction and gas cooktops. Ovens flag an F-code for a sensor or relay fault, and induction cooktops fail at the coil or power board, all of which we test and replace.
Are Your Bosch Parts Model-Specific?
Yes. We install OEM Bosch drain pumps, heating elements, valves, sensors, and control boards matched to your exact model.
