Bosch is the quiet workhorse of the high-end kitchen: dishwashers that run near-silent, precise induction cooktops, and Benchmark ovens that hold their calibration. Because Bosch is a BSH product, its diagnostics are code-driven, and the E-code system is one of the clearest in the industry when the code is read correctly and confirmed at the part.
Models We Service
- Benchmark, 800, and 500-series dishwashers, panel-ready and integrated
- Benchmark and 800-series wall ovens, single and double
- Induction, gas, and electric cooktops
- Speed and steam ovens
- Built-in and counter-depth refrigeration
Error and Fault Codes
Bosch dishwasher E-codes are model-specific and widely documented. The most common are below; ovens use their own fault indications for sensor and heating circuits.
| Code | Typical Meaning | What We Do |
|---|---|---|
E15 | Water in the base tray, leak protection tripped | Dry the tray, find and fix the leak source |
E24 | Drainage fault (clog or drain pump) | Clear filter and hose, test the drain pump |
E22 | Filter or flow blockage | Clean main and fine filters, verify circulation |
E09 | Heating element circuit fault | Test heater and thermistor, replace failed part |
| Oven sensor fault | Temperature sensor open or shorted | Ohm-test the sensor, replace out of range |
Common Problems We Fix
The E15 leak-protection shutdown is the single most common Bosch dishwasher call, and it is usually a small drip, a hose, a seal, or a fill-valve weep, that filled the base tray rather than a catastrophic leak. E24 drainage faults follow, and are almost always a clogged filter or a jammed drain pump. On the ovens, the temperature sensor and heating element are the usual failures, and an E09-family heating fault points at the element circuit. On induction cooktops, a dead zone means that zone's coil or inverter. Bosch parts availability is good, which keeps these repairs quick.
