The E11 error on your Bosch Dishwasher means the machine has detected that water is taking too long to fill the tub during the intake cycle. Checking the water supply line and inlet filter usually resolves it.
| Error code | E11 |
|---|---|
| Meaning | Slow or restricted water intake — the dishwasher isn't filling within its expected time window |
| Severity | Medium — the dishwasher won't complete a wash cycle until resolved |
| Time to fix | 10–30 minutes |
| Tools needed | Adjustable pliers, small bucket or towel |
What the E11 error means
Every Bosch dishwasher monitors how long it takes to reach the correct water level at the start of a cycle. If that fill process takes longer than the internal timer allows, the control board flags it as E11 and pauses the cycle. This is almost always a water flow problem rather than an electronic fault, so it's worth checking the basics before assuming a part has failed.
Common causes
- Kinked, twisted, or crushed water inlet hose behind the dishwasher
- Household water supply valve only partially open
- Blocked or clogged inlet filter screen where the hose connects to the machine
- Low mains water pressure affecting fill speed
- Faulty water inlet valve that isn't opening fully
- Float switch stuck or misaligned, causing incorrect level readings
How to fix the E11 error
- Check the water supply valve: Confirm the shutoff valve under the sink or behind the dishwasher is fully open, not just partially turned.
- Inspect the inlet hose: Pull the dishwasher out carefully and look for kinks, twists, or bends in the hose that could restrict flow.
- Clean the inlet filter: Disconnect the hose from the dishwasher (have a towel ready), remove the small mesh filter, and rinse away any sediment or debris.
- Test water pressure: Run a nearby tap to check pressure is normal; very low pressure from the mains can trigger this fault.
- Reconnect and run a test cycle: Reattach the hose securely, turn the water supply back on, and start a short cycle to see if E11 clears.
- Call a technician if it persists: If the fault returns after checking the above, the inlet valve or float switch likely needs professional inspection or replacement.
FAQ
Can I keep using the dishwasher with an E11 error showing?
No, the cycle will stay paused until enough water fills the tub, so it's best to fix the flow issue first.
Is E11 the same as a leak error?
No, E11 relates to slow filling, not leaking. Bosch uses separate codes for leak detection.
Will resetting the dishwasher clear the E11 code?
A reset may clear the display temporarily, but the error will return on the next cycle if the underlying water flow problem isn't fixed.
