E14

Flow Meter Fault

Severity

Medium

The error code E14 on your Bosch Dishwasher indicates a specific system failure categorized as "Flow Meter Fault". This guide walks you through the most likely causes and the correct repair sequence.

Owner's Summary

The flow meter is a small spinning paddle wheel in the water line that counts how much water enters the machine. When it gets stuck with debris or limescale, the machine cannot measure water accurately and stops with E14. A vinegar soak often fixes this for free.

Symptoms

Bosch dishwasher stopping mid-fill, incorrect water amount, E14 code

Common Causes

Debris jamming flow meter turbine
Faulty flow meter sensor
Wiring fault to flow meter
Limescale buildup on flow meter impeller

How to Fix

1 Remove inlet hose and inspect flow meter turbine for debris
2 Spin turbine manually to verify it rotates freely
3 Descale flow meter housing with vinegar soak
4 Replace flow meter if turbine is damaged or sensor signal is absent

Tools You'll Need

Pliers Vinegar or Descaler Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

The Bosch flow meter uses a Hall-effect sensor to count turbine rotations and convert them to water volume. The EGO module accumulates pulse counts and compares to target volumes per program. E14 is triggered when pulse rate is zero or erratic during a fill phase.

Is It Safe to Keep Using?

Low risk. The machine simply stops filling. Resolve within a week.

Technician's Pro Tip

The flow meter on Bosch dishwashers is inline with the inlet valve — accessible by pulling the machine out and disconnecting the fill hose. A toothpick can clear debris from the turbine housing in minutes. Always try cleaning before ordering a replacement.
