Bosch Dishwasher E06 Error Code: Door Sensor Causes, Reset, and Fix

The door is shut, yet the dishwasher still refuses to start. The Bosch dishwasher E06 error code can appear when the control misses the expected door-sensor response. Some displays show E6 without the zero. Does that change where you should begin checking?

Door fit, the latch, and wiring come first. The sections below explain the reset and those checks before covering the model-dependent aqua sensor assessment. You will see how a mechanical latch differs from an electronic door sensor, which tests need a technician, and how the cost of a latch, sensor, or control affects the repair decision.

Quick Facts

Use these details to plan the work:

• Difficulty: Easy to Moderate
• Time: 10 minutes for a reset and latch check, 45 to 60 minutes for a latch or aqua sensor swap
• Tools: Torx T20 driver, Phillips screwdriver, soft cloth, flashlight, multimeter
• Part cost: $0 to $200
• Skill level: Beginner for alignment, intermediate for part replacement

What Does the E06 Error Code Mean on a Bosch Dishwasher?

E06 usually means the control detected a door-sensor fault and cannot confirm that the door is safely closed. On models that assign this code to the aqua sensor, the model-specific diagnosis must also include that sensor.

These symptoms help narrow the first check.

• The cycle will not start.
• The machine stops when the latch loses contact.
• The door does not catch securely.
• The code remains even though the door appears closed.

The aqua sensor measures how cloudy the wash water is. That job is different from confirming a closed door, so do not assume one sensor can replace the other. The full model determines which circuit E06 identifies.

Is E6 the Same as E06 on a Bosch Dishwasher?

E6 and E06 can be different display forms of the same dishwasher warning. The missing leading zero does not by itself call for a different latch or sensor.

Record these details before choosing a repair.

• The complete displayed characters
• The full dishwasher model number
• Whether the code appears before starting or during the wash
• Whether the door catches normally

What Causes the E06 Door Sensor Error on a Bosch Dishwasher?

A door that is not fully latched, a misaligned strike, or a worn latch switch can prevent a valid closed-door signal. Loose wiring and model-dependent sensor faults can also cause the warning.

Compare these findings with the timing of the code.

An electronic sensor and a simple continuity switch do not use the same test. A continuity check belongs to the mechanical switch specified by the model, not to an unknown electronic sensor.

How Do I Reset a Bosch Dishwasher After an E06 Error?

Follow these steps to cancel the stopped cycle and retry the door signal.

1. Open the door and close it firmly without slamming.
2. Hold Start for 3 to 5 seconds to cancel.
3. Switch off power at the breaker for 5 minutes.
4. Restore power and run a short cycle.

Did the door fail to catch again? That is more useful evidence than the reset result alone. A Bosch dishwasher E06 error code that returns needs the latch and circuit checks rather than extra closing force.

How Do I Check the Bosch Dishwasher Door Latch and Aqua Sensor?

Follow these steps for the power-off checks on the appropriate model.

1. Disconnect power.
2. Remove the inner door screws needed to reach the latch.
3. Test a specified mechanical latch switch for continuity as the latch changes position.
4. Remove the toe panel to reach a model-fitted aqua sensor at the sump.
5. Disconnect that sensor, clean its accessible lens, and assess the connector.

How to Fix a Bosch E06 Error Step by Step

Follow these steps to assess the door-sensor path before a control replacement.

Phase 1: Reset the Dishwasher and Confirm the Door Latches

1. Disconnect power.
2. Wait at least 2 to 3 minutes.
3. Restore power and check E06.
4. Inspect the door opening for debris or obstructions.
5. Remove anything preventing proper closure.

Phase 2: Inspect and Test the Door Latch Switch

1. Inspect the latch for damage or poor alignment; correct alignment or replace confirmed damage.
2. Have a qualified tester restore water and power for the model-specific sensor test.
3. Identify the door sensor and its harness test points.
4. Select DC volts.
5. Check the closed-door sensor circuit only on the matching design: above 10 VDC points to the sensor; below 10 VDC points toward the power module.

Phase 3: Clean and Check the Aqua Sensor and Its Wiring

1. Disconnect power and inspect door-sensor wiring for damage or loose connections.
2. Replace damaged wiring; assess the control last if other checks pass.
3. Clean and check a model-fitted aqua sensor and connector with power disconnected.

Phase 4: Replace the Failed Part and Run a Test Cycle

1. Fit the confirmed matching replacement and run a short cycle after reassembly.

The powered sensor check can expose you to serious electric shock. Leave it to a technician unless you have the training to test live appliance circuits safely. The voltage rule is specific to the matching sensor circuit and is not a general test for every door switch.

Should You Replace the Door Latch, the Aqua Sensor, or the Control Board?

Choose the part supported by its own check.

• Strike adjustment, $0: Suitable when alignment alone prevents closure.
• Door latch, $30 to $70: Suitable for a failed mechanical latch or specified switch.
• Aqua sensor, $35 to $80: Suitable for a confirmed sensor fault after cleaning and connector checks.
• Control board, $150 to $200: Consider only when the relevant sensors and wiring pass.

The complete model number is essential before ordering. A Bosch dishwasher E06 error code does not show which latch style, sensor design, or control your machine uses.

FAQ

What Does E06 Mean on a Bosch Washing Machine?

Do not apply this dishwasher door-sensor procedure to a washing machine. Use the washer’s exact model and code information to identify its own fault.

When Should I Call a Technician for a Bosch E06 Error?

Call when the door closes correctly but E06 remains, an electronic sensor test is needed, or the code assignment is unclear for the model. Powered testing and control faults are good reasons to use service.

Can a Warped Door Cause E06?

A distorted door can keep the latch and strike from meeting correctly. Replacing a sound sensor will not restore the physical alignment of a warped door.

A Door the Control Recognizes

A normal cycle needs both a secure latch and a valid sensor response. Use those two findings to guide the repair for a Bosch dishwasher E06 error code, then match the replacement to the model.

Confirmed the door latch switch or the aqua sensor is behind the E06 code? Look up the exact part for your Bosch model number and order the replacement so the next cycle starts on the first press.
