Step-by-Step DIY Fix Guide
- SAFETY: Turn off power before disconnecting any hose or supply fitting.
- Confirm the water supply valve is fully open, not just partly open.
- Inspect the inlet hose for kinks, crushing, or obvious restriction behind the dishwasher.
- Compare water flow at a nearby sink fixture if you suspect low household pressure.
- Use the Bosch manual before ordering any fill-sensor or inlet components.
If E14 returns after the basic fill checks
- If supply conditions look normal, the fault is more likely inside the fill-measurement path.
- If another water-related code appears with E14, compare whether the problem looks more like low fill than bad metering alone.
- If the dishwasher fills weakly and pauses early, keep the water-supply path in the diagnosis too.
What This Error Means
Bosch dishwasher error E14 means the machine is not seeing normal water-fill metering. In practical terms, the dishwasher may still have a supply-side issue, but the code is more specific than a simple no-water warning.
The first useful checks are still the simple ones: confirm the water supply valve is fully open, the inlet hose is not kinked, and household water pressure is not unusually low.
If those basics look normal and E14 keeps returning, the next likely issue is the flow-meter path or another internal fill-measurement fault.
Most Likely Cause by Symptom
The dishwasher starts but does not seem to fill normally before pausing.
Likely cause: The machine is not measuring incoming water the way it expects.
Check first: Confirm the supply valve is fully open and inspect the inlet hose path first.
The code returns even though the dishwasher still gets some water.
Likely cause: The fill-measurement path may be inaccurate rather than fully blocked.
Check first: Treat the supply checks as the first step, then stop at the manual if the code returns.
Common Causes
- The water supply is restricted and fill flow is not being measured correctly.
- The inlet hose is kinked, crushed, or partially blocked.
- The flow meter or fill-sensing path is not reporting accurately.
- A related internal fill-control fault is interrupting normal metering.
What Not to Do
- Do not keep restarting the cycle if the dishwasher is not filling normally.
- Do not assume the main control board is the first failed part when the code points more directly to fill measurement.
Model and Display Variation Notes
Model-family notes
- Bosch fill and flow-meter layouts vary by dishwasher series, but E14 still points first to water-fill measurement rather than drain problems.
- This code can overlap with more general fill complaints if supply pressure is borderline at the same time.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Common parts
- Flow meter ($30–$70)

When Not to Keep Troubleshooting
E14 returns after the supply valve and hose checks are complete.
- Water supply looks normal but the dishwasher still will not meter fill correctly.
- You suspect a flow meter or other internal fill-sensing fault.
How to Prevent It Recurring
- Check the inlet hose for kinks annually
- Ensure the supply valve under the sink is fully open
Related Error Codes
E15
The safety switch has detected water in the base of the dishwasher, so the flood protection system has activated.
E16
Bosch dishwasher error E16 usually means there is a problem with the water fill system, often because the inlet valve is not controlling water flow properly.
E3000
There is a flow meter failure or an issue with water flowing into the dishwasher or the filling system.
