Bosch Dishwasher E14 Error: Flow Meter Sensor Replacement

The Bosch E14 error code appears when the flow meter sensor isn't functioning correctly. This sensor measures incoming water flow and volume, helping the control board determine if proper water amounts are entering the dishwasher.

Flow Meter Function

Modern Bosch dishwashers use a flow meter in the water inlet system to precisely measure water entering the tub. This allows exact water usage for efficiency and ensures proper fill levels. The flow meter contains a small turbine that spins as water passes through, generating electrical pulses the control board counts. E14 indicates the sensor has failed, provides implausible readings, or isn't receiving water flow.

Replacement Procedure

• Step 1: Turn off the water supply valve and disconnect power. Water will spill during flow meter removal, so have towels ready.
• Step 2: Pull the dishwasher out slightly to access the inlet valve area at the front left.
• Step 3: Locate the flow meter—it's typically integrated into or directly connected to the water inlet valve assembly.
• Step 4: Disconnect the electrical connector from the flow meter sensor. Note wire positions for reassembly.
• Step 5: If the flow meter is separate from the inlet valve, loosen hose clamps and remove it from the water line. If integrated, you'll need to replace the entire inlet valve assembly.
• Step 6: Before installing the new flow meter, inspect it for debris or sediment. Install any included screens or filters.
• Step 7: Install the new flow meter, ensuring the flow direction arrow points toward the dishwasher. Tighten hose clamps securely and reconnect wiring.

Turn on the water supply and check for leaks around all connections. Restore power and run a test cycle. The dishwasher should fill normally and the E14 error should not return. Flow meters rarely fail unless damaged by sediment or debris, so consider installing a whole-house water filter if you have water quality issues. The flow meter ensures efficient water usage and proper wash performance—don't skip this repair.
