🍽️ Bosch dishwasher displays E06 error (water overflow)
Step-by-step troubleshooting guide — 5 steps, Dishwasher.
🔧 Troubleshooting Steps
- Check the door is fully closed and latched. A slightly open door can trigger the overflow sensor
✓ Expected: Door fully latched
- Check the drain hose — it must be inserted into the standpipe or drain but NOT submerged. If the hose end is below the water level in the standpipe, water back-siphons
✓ Expected: Hose end above water level in standpipe
- Check the float switch (overflow sensor) inside the tub. It should move freely up and down. If it's stuck in the 'up' position, it triggers E06 falsely
✓ Expected: Float moves freely
- If the float is free, check the drain pump. A failing drain pump can cause water to accumulate faster than it can drain
✓ Expected: Pump runs, water drains
- If E06 persists, check the water level sensor (pressure switch) on the top of the tub. A stuck sensor reads 'water present' when the tub is empty
✓ Expected: Sensor diaphragm free
