The E14 error on your Bosch Dishwasher means the appliance has detected a fault with the flow meter or turbidity sensor that measures water clarity during the wash cycle. This usually stops the wash cycle partway through or prevents it from starting properly. In many cases it's caused by a dirty sensor or a temporary electronic glitch that can be cleared with a reset.
| Error code | E14 |
|---|---|
| Meaning | Flow meter/turbidity sensor fault — the dishwasher can't accurately read water flow or clarity |
| Severity | Medium — the dishwasher may still run but with reduced washing performance |
| Time to fix | 15–40 minutes |
| Tools needed | Screwdriver, soft cloth, multimeter (optional) |
What the E14 error means
Bosch dishwashers use a flow meter and turbidity sensor near the water inlet or sump area to track how much water enters the machine and how dirty that water is. When the E14 code appears, the control board has received an inconsistent or missing signal from this sensor. This can happen because of debris buildup, a wiring issue, or the sensor itself failing over time.
Common causes
- Food debris or limescale blocking the flow meter or sensor
- Loose or corroded wiring connector at the sensor
- A faulty flow meter that needs replacing
- Blocked or kinked water inlet hose reducing flow
- Electrical interference or a temporary control board glitch
- Sensor damaged during a previous repair or cleaning
How to fix the E14 error
- Power cycle the dishwasher — Turn off the appliance at the wall, wait 2–3 minutes, then switch it back on. This clears many temporary sensor glitches.
- Check and clean the filter and sump area — Remove the lower filter assembly and rinse away any trapped food particles or limescale that could be affecting the flow sensor.
- Inspect the water inlet hose — Make sure it isn't kinked, twisted, or restricted, since low flow can trigger the same fault reading.
- Locate and inspect the flow meter connector — With the power disconnected, open the base panel and check the wiring plug for corrosion or a loose fit. Reseat it firmly.
- Test the sensor with a multimeter — If you're comfortable with basic electrical testing, check the flow meter's resistance against the manufacturer's spec sheet to confirm it's working.
- Replace the flow meter or turbidity sensor — If cleaning and reseating don't help, the part itself may need replacing. This is a straightforward swap on most Bosch models but may need a spare part order.
If you're already comfortable working with small appliance electronics from tasks like troubleshooting a Bosch Drill Won'T Start: Causes and How to Fix It issue or sorting out a Bosch Drill Battery Not Connecting: Causes and How to Fix It problem, the same careful, methodical approach applies here — always disconnect power before touching wiring.
FAQ
Can I keep using the dishwasher with an E14 error showing?
You can sometimes run a cycle, but washing performance may suffer since the machine can't properly judge water clarity. It's best to fix the fault before regular use.
Does E14 mean I need a new dishwasher?
No. E14 almost always points to a sensor or wiring issue, not a failure of the whole appliance. Most fixes involve cleaning or replacing a low-cost part.
Why does my dishwasher keep showing E14 after cleaning the filter?
If the error returns, the flow meter connector may be loose or the sensor itself may be faulty. Similar to diagnosing a Bosch Drill Overheating During Use: Causes and How to Fix It problem, it helps to rule out simple causes first before assuming a part needs replacing.
