We repair Bosch across Johns Creek, with appointment timing confirmed at booking. Bosch sits in the BSH family and is best known for quiet, panel-ready dishwashers, and its wall ovens share much of that same electronic and sensor architecture. What sets a good Bosch repair apart is reading the E-series fault code correctly, then confirming the actual failed part with a meter rather than swapping components in the order the code chart lists them. A code like E15 or E24 tells you the area, not the exact cause. Service is scheduled in Johns Creek and nearby communities including Suwanee, Alpharetta; address coverage is confirmed when requested. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval. Written terms are provided with the repair. Parts selection is confirmed after diagnosis.
Models We Service
Each Bosch line has its own control board, sensor set, and service quirks. The model and serial are on a plate along the edge of the dishwasher door or on the frame of a wall oven. Give us that number when you book and we will pin down the family before we arrive.
800 Series Dishwashers
- 800 Series dishwashers with the CrystalDry drying system, the FlexSpace third rack, and the panel-ready fronts common in custom Johns Creek cabinetry.
- 800 Series models with the InfoLight floor beam and the RackMatic adjustable middle rack, which affect both loading and the spray pattern we test.
Benchmark Dishwashers
- Benchmark dishwashers, the top Bosch tier, with the fully flush panel-ready front, the CrystalDry zeolite drying system, and the AutoAir door.
- Benchmark units with the illuminated interior and the PrecisionWash sensor cycle that we verify during a diagnosis.
Wall Ovens
- 800 Series single and double wall ovens with European convection and a temperature-probe cooking mode.
- Benchmark wall ovens, including combination and steam-capable models set into tall cabinetry runs.
Bosch reuses pumps, sensors, and control boards across several of these families, so an accurate model number is the fastest route to the correct part on the diagnostic visit.
Error & Fault Codes
Bosch is one of the brands that publishes clear E-series fault codes, which speeds up diagnosis when you read them correctly. A code identifies the affected system, not the exact failed part, so we still confirm every reading with a meter before replacing anything. The table below lists the Bosch E-codes we see most in Johns Creek, what each one means, and what we check.
| Code | Meaning | What We Check |
|---|---|---|
| E15 | The anti-flood tray in the base has water in it and the float switch has tripped, so the dishwasher shuts off the fill to protect the floor | Trace the leak to its source, usually a hose, the sump, the pump seal, or the door gasket, dry and reset the tray, then repair the cause so the code stays gone |
| E24 | The dishwasher cannot drain: the drain path is blocked, the hose is kinked, or the drain pump is failing | Clear the filter and drain path, check the hose and air gap, test the drain pump for continuity and free rotation, and replace the pump if it is seized or open |
| E22 | Filter and drain fault: the fine and coarse filters or the sump are clogged and the machine cannot move water out | Pull and clean the filter stack, clear the sump and check valve, verify drainage, and confirm the code clears through a full cycle |
| E09 | Heating fault: the flow-through heating element is not warming the wash water, so dishes stay cool and cycles run long | Test the flow-through heater element and its thermistor, check the wiring and control drive, and fit an OEM heating element if it reads open |
| Repeated E15 after draining the tray | The base water was cleared but the underlying leak was not repaired, so the float trips again on the next cycle | Pressure-check the water path, inspect the hose clamps, sump gasket, pump seal, and door gasket, and repair the actual leak source |
| Oven temperature or door fault (wall oven) | A temperature sensor is out of range or the motorized door lock will not confirm for a self-clean cycle | Test the sensor resistance against spec, check the door lock motor and switches, and replace the sensor or lock as the readings show |
Common Problems We Fix
Beyond the codes above, these are the Bosch calls we handle most in Johns Creek. We diagnose first and replace parts only after the fault is confirmed with a meter or on the bench.
- Dishwasher will not drain. Usually an E24 or E22 condition: a clogged filter or sump, a kinked hose, or a failing drain pump, cleared or replaced as the test shows.
- Water in the base, machine dead. An E15 anti-flood trip caused by a leak we trace and repair at the source rather than just draining the tray.
- Dishes come out cool or cycles run long. An E09 heating fault from a failed flow-through element or its thermistor.
- Dishes not drying. A CrystalDry zeolite or heating issue, a door not opening at the end of the cycle, or a rinse-aid delivery fault.
- Poor wash results. A blocked spray arm, a worn diverter, a clogged filter, or a circulation pump that has lost pressure.
- Dishwasher will not start or fill. A door latch, a water inlet valve, or a control fault, verified before the part is replaced.
- Wall oven not heating. A failed bake or broil element, a drifting temperature sensor, or a relay on the control board.
- Leaking at the door. A set or torn door gasket, a loose sump connection, or a spray arm directing water past the seal.
The most common Bosch mistake is tipping the dishwasher to drain the anti-flood tray, watching the E15 clear, and calling it fixed. The float only trips because water reached the base, and that water came from somewhere. Until the leaking hose, sump gasket, pump seal, or door gasket is found and repaired, the tray refills and E15 returns on the next cycle. The real fix is tracing the leak to its source, which is what protects your floor and the cabinetry around it.
Maintenance & Guides
Clean the filter on a schedule. The single most valuable habit for a Bosch dishwasher owner is pulling and rinsing the filter stack at the bottom of the tub every few weeks. A clogged filter is behind a large share of the E22 and E24 drainage codes and most poor-wash complaints. Our Bosch repair guide walks through the dishwasher and wall oven families and when a symptom is worth a service call, and our detailed look at the Bosch E fault codes explains what each E-code is telling you.
Act on an E15 early. Because E15 signals water where it should not be, treating it as urgent protects the floor and the surrounding cabinetry, which matters in the custom millwork common in Johns Creek kitchens. Our guide to the Bosch dishwasher E15 and E24 codes covers how we trace a leak and clear a drain blockage so the fault does not come back.
