The E11 error on your Bosch Dishwasher means the machine has not detected enough water flowing in within the expected fill time. This is usually caused by a water supply problem or a blocked inlet, and it can often be fixed without calling an engineer.
| Error code | E11 |
|---|---|
| Meaning | Water inlet fault — the dishwasher did not fill with enough water in the allotted time |
| Severity | Medium — the dishwasher will not run a cycle until water flow is restored |
| Time to fix | 10–40 minutes |
| Tools needed | Adjustable pliers, a bucket, and a torch (flashlight) |
What the E11 error means
Bosch dishwashers monitor how quickly water enters the tub during the fill stage of a cycle. If the machine doesn't sense enough water within a set time window, it stops the cycle and displays E11 to warn you that something is restricting water flow. This is one of the more common Bosch dishwasher fault codes and is almost always related to the water supply rather than an internal electrical fault.
In most cases the cause is simple: a closed tap, a kinked hose, or a blocked filter. Less often, the water inlet valve itself has failed and needs replacing.
Common causes
- Water supply tap to the dishwasher is turned off or only partly open
- Kinked, trapped, or crushed inlet hose behind the appliance
- Blocked inlet filter (the small mesh screen where the hose connects to the machine)
- Low household water pressure feeding the kitchen
- Faulty water inlet valve that no longer opens fully
- Aquastop or safety valve triggered by a suspected leak
How to fix the E11 error
- Check the water tap — Make sure the stopcock or valve feeding the dishwasher is fully open. A partly closed tap is the most common cause of this fault.
- Inspect the inlet hose — Pull the dishwasher out carefully and look for any kinks, twists, or trapped sections in the hose. Straighten it out and make sure nothing is pinching it against the wall or cabinet.
- Clean the inlet filter — Disconnect the hose from the tap end, remove the small mesh filter, and rinse it under running water to clear any debris or limescale buildup.
- Check water pressure — Run the kitchen tap on full and check the flow is strong and steady. Very low mains pressure can trigger this error even when everything else is fine.
- Reset the dishwasher — Turn the machine off at the wall, wait two minutes, then switch it back on and start a new cycle to see if the error clears.
- Call a Bosch-approved engineer — If water flow is normal and the error persists, the inlet valve itself may be faulty and will need testing or replacing by a qualified technician.
FAQ
Can I still use the dishwasher with an E11 error showing?
No. The cycle will not start properly until the machine detects enough incoming water, so it's best to fix the cause first.
Is E11 dangerous or does it mean a leak?
Not usually. It simply means water isn't entering fast enough — it's a flow issue, not typically a safety shutdown, though a blocked Aquastop valve can occasionally be involved.
Will cleaning the filter really fix this?
Yes, in many cases. A blocked inlet filter is one of the most common causes of the E11 code and takes just a few minutes to clean.
