What Bosch E08 error means on your dishwasher
Error code E08 indicates that the water level in the dishwasher dropped below the minimum threshold during a wash cycle. The flow meter or pressure sensor detected less water than expected, and the control board paused the cycle to protect the circulation pump and heater from running dry. If you encounter the bosch e08 error, professional Bosch dishwasher repair may be needed.
Symptoms
- The cycle stops mid-wash and E08 appears
- You may hear the circulation pump running louder than normal or cavitating (churning air)
- Opening the door reveals little or no water in the tub
- Dishes are only partially cleaned
Common causes
- Overturned dishes or cookware — large bowls, pots, or sheet pans placed incorrectly can trap water and redirect it out through the door seal
- Spray arm obstruction — tall items blocking the spray arm force water sideways and can push it past the door gasket
- Water supply interruption — someone turned off the water valve, or a supply issue caused flow to drop during the fill phase
- Leaking inlet valve — the valve closes but doesn’t fully seal, causing intermittent loss of water pressure during the cycle
- Drain pump activating incorrectly — a faulty drain pump relay can cause brief drain events that lower the water level

Troubleshooting steps you can try
- Rearrange the load — ensure no bowls or pots are facing up (collecting water), and verify nothing blocks the spray arm rotation.
- Check the water supply — confirm the shut-off valve under the sink is fully open and the supply hose is not kinked.
- Inspect the door seal — look for food debris or damage on the rubber gasket around the door opening.
- Reset and run empty — power cycle the dishwasher and run an empty cycle. If E08 doesn’t appear without dishes, the issue was load-related.
- Check Bosch support — visit Bosch’s official dishwasher support page for model-specific troubleshooting guides and tech notes.
When to call a technician
If E08 occurs on empty cycles, the flow meter, inlet valve, or drain pump control may be faulty. A technician can test the flow meter output and check the drain pump for intermittent operation. Water level issues that aren’t load-related usually point to a component that needs replacement. Codes may vary by model generation and series. Schedule a certified Bosch technician for fast, reliable diagnosis and repair.
