Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power.
- Remove and clean the filter. Remove debris from pump area.
- Run a descaling cycle. Restore power and test.
If the warning comes back after restart
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
What This Error Means
Error code E6002 on your Bosch dishwasher indicates: The heat pump is blocked. The appliance detects this condition through its built-in sensors and halts the current cycle to prevent further damage. Depending on the model, the code may flash on the display panel, appear on a digital readout, or cause the status lights to blink in a specific sequence. The dishwasher will not resume normal operation until the underlying fault is resolved.
The most frequent cause of error E6002 is same as e21 — heat pump blockage on premium models. When this happens, the dishwasher's control board detects the abnormal sensor reading or motor response and triggers the fault code as a protective measure. Other contributing factors are listed in the causes section below — working through them in order is the fastest path to a fix.
Error E6002 is one of the most DIY-friendly Bosch dishwasher fault codes. Most homeowners can clear it in under 15 minutes without tools or replacement parts. Follow the step-by-step guide below exactly — skipping steps is the most common reason the error comes back.
The most visible symptom of E6002 is standing water at the bottom of the tub at the end of a cycle — the dishwasher failed to pump it out. The water may appear cloudy from food particles or detergent residue. Do not run another cycle until the fault is cleared, as this could allow water to overflow onto the floor.
