Bosch Dishwasher E14 Error Code — What It Means
E14 means the flow meter is not sending the pulse signal the board expects while the fill valve is open. The board thinks water is not moving through the machine.
The flow meter counts water with a tiny spinning wheel and a reed switch. An intermittent E14 usually means that reed switch is on its way out, but a clogged inlet screen can fake the same symptom.
Common Causes
- Failing reed switch sensor The flow meter reed switch weakens and stops pulsing reliably as water passes.
- Clogged inlet screen Grit in the inlet filter slows water so the meter wheel barely turns.
- Stuck flow meter wheel Scale or debris jams the little impeller wheel inside the flow meter.
- Kinked or restricted inlet hose A pinched fill hose cuts flow below what the meter can register.
- Loose flow meter wiring A loose connector at the meter breaks the pulse signal to the board.
Step-by-Step Fix
- Cut power at the breaker and shut the household water supply valve.
- Disconnect the fill hose and clean the inlet screen filter where the water enters.
- Check the fill hose for kinks and confirm the supply valve is fully open.
- Locate the flow meter on the inlet line and check its wiring connector is seated tight.
- Tap or flush the flow meter to free a stuck wheel, then confirm it spins.
- Restore water and power, run a cycle, and confirm E14 clears. If it returns, replace the flow meter sensor.
Parts Often Needed
| Part | Notes |
|---|---|
| Bosch dishwasher flow meter sensor | Amazon | The reed switch sensor is the most common E14 fix. Match the model number. |
| Bosch dishwasher water inlet valve with flow meter | Amazon | Some models combine the valve and meter in one matrix assembly. |
| Bosch dishwasher inlet screen filter | Amazon | Replace if the screen is damaged and cannot be cleaned. |
When to Call a Pro
If the inlet screen is clean and the hose is clear but E14 keeps coming back, the flow meter sensor or matrix assembly is failing. Call a technician if accessing the inlet assembly under the unit is more than you want to take on.
