Sequential Factory Diagnostic Tree

Perform each diagnostic step in order. Disconnect electrical power and turn off utility shutoffs before inspecting wiring or internal mechanical assemblies.

Step 1: Physical & Electrical InspectionMultimeter & Visual

Action: Remove left side stainless outer panel to expose the large plastic water inlet matrix (heat exchanger).

Bench Test: Inspect the small printed circuit board (flow meter reed switch) clipped into the lower corner of the water matrix.

Expected Standard: Reed switch board dry, fully seated in matrix slot, and harness plugged in firmly.

If Failed / Out of Spec:

Reseat or dry reed switch PCB.

If Passed:

Proceed to Step 2.

Step 2: Physical & Electrical InspectionMultimeter & Visual

Action: Initiate a test fill cycle while observing the small spinning impellor inside the flow meter housing.

Bench Test: Check if plastic turbine wheel spins vigorously as incoming water flows.

Expected Standard: Turbine wheel spins freely without binding.

If Failed / Out of Spec:

Replace water inlet matrix assembly (00668270) due to calcified turbine.

If Passed:

Proceed to Step 3.

Step 3: Physical & Electrical InspectionMultimeter & Visual

Action: Measure DC pulse voltage across reed switch output pins during active water fill.

Bench Test: Connect multimeter leads set to DC volts across the two reed switch output wires.

Expected Standard: Rapid fluctuating voltage signal (0V to 5V pulses) as magnet passes reed switch.

If Failed / Out of Spec:

Replace flow meter reed switch sensor board (00611317).

If Passed:

Proceed to Step 4.

Step 4: Physical & Electrical InspectionMultimeter & Visual

Action: Inspect wiring harness between reed switch and main control module in rear base.

Bench Test: Test continuity across harness wires and check for pinched wire in hinge channel.

Expected Standard: 0 ohms continuity; clean pins.

If Failed / Out of Spec:

Repair harness wiring.

If Passed:

Replace main power module (11028637).

Frequently Asked Questions: Bosch E14

What causes Bosch dishwasher error code E14?

The reed switch sensor on the left-side water matrix impellor flow meter is not sending pulses to the control board despite water entering the tub.

Can I reset the E14 code by unplugging the dishwasher?

While disconnecting power for 5 minutes may temporarily clear the display control memory, the E14 code will reoccur once the microcontroller detects the mechanical or electrical fault again.

What OEM replacement parts are required for Bosch E14?

Common OEM replacement components include: Flow Meter Reed Switch Sensor PCB (OEM #00611317), Water Inlet Matrix Heat Exchanger (OEM #00668270), AquaStop Water Inlet Solenoid Valve (OEM #00668157).
