Bosch Dishwasher E06 Error Code — What It Means
Bosch identifies the E06 error code as a door sensor circuit fault or error. This means the control board is not detecting a proper closed-door signal from the sensor circuit. The machine will not start a wash cycle until the door is recognized as securely latched and the circuit reads correctly.
In practice, E06 is tied to the door sensor, the latch-sense circuit, or the wiring that connects them to the control board. The door may not be closing completely, the sensor itself may have failed, or a connector or wire in the circuit may be loose or damaged. Bosch recommends a power reset as the first troubleshooting step, and if the code returns after that reset, the manufacturer directs you to contact support or service.
Common Causes
- Door not fully closed or latched An obstruction, misaligned latch, or warped door gasket can prevent the door from engaging the latch switch completely, triggering the sensor circuit fault.
- Defective door sensor or latch switch The door sensor assembly itself may have failed and no longer sends a closed-door signal to the control board even when the door is latched.
- Loose or damaged sensor wiring or connector The harness or connector between the door sensor and the control board can work loose, corrode, or sustain physical damage, breaking the circuit.
- Control board circuit issue In rare cases the door-sensor input circuit on the control board may be faulty, though this is less common than sensor or wiring problems.
Step-by-Step Fix
- Turn off power at the breaker or unplug the dishwasher and wait a full 30 seconds to allow the control board to clear its memory, then restore power and test whether the E06 code returns.
- Open and close the door firmly, listening and feeling for a solid latch click, and check that no dish racks, utensils, or debris are blocking the door from seating fully against the gasket.
- Inspect the door gasket and latch striker for damage, warping, or misalignment that would prevent the latch from engaging the sensor switch completely.
- Remove the lower access panel or door panel (consult your model’s service manual for fastener locations) to expose the door sensor connector and wiring near the latch assembly.
- Check the door sensor connector and harness for loose pins, corrosion, or visible wire damage, and reseat the connector firmly, then test the machine.
- Test or replace the door sensor assembly if the connector and wiring are intact, the door closes properly, and the E06 code persists after the reset.
- If the code returns after sensor replacement, the control board’s door-sensor input circuit may be faulty and Bosch recommends contacting service or support for further diagnostics.
Parts Often Needed
| Part | Notes |
|---|---|
| Bosch Dishwasher Door Sensor / Latch Switch | Amazon | Verify the part number for your specific Bosch model before ordering, as door sensor assemblies vary by series. |
| Door Sensor Wiring Harness | Amazon | Needed only if you find visible cuts, pinch damage, or corrosion in the wiring between the sensor and control board. |
When to Call a Pro
Call a professional if the E06 code persists after you have performed a full power reset, confirmed the door closes and latches properly, and inspected the sensor connector and wiring for obvious damage. Diagnosing a faulty control board circuit or safely accessing the door sensor assembly on some Bosch models requires disassembly of the door panel and familiarity with the specific wiring layout. If you are not comfortable working inside the door or around live electrical connections, or if you have already replaced the door sensor and the fault returns, Bosch recommends contacting an authorized service technician for further diagnostics and repair.
