Bosch E07 Code: Flow Sensor Problem Explained

Quick Answer

Bosch E07 means the flow sensor turbine is not spinning - it is jammed with mineral scale, not necessarily broken. Cleaning the stuck turbine resolves E07 without replacing any parts in most cases. Access the sensor near the inlet valve, remove the cap, and manually spin the turbine with a toothpick - it should rotate freely. Soak in vinegar to break up scale.

Bosch E07 means the flow sensor inside the dishwasher is not detecting water moving. Either water is not actually flowing (in which case 5UC or E17 would typically appear first), or the flow sensor turbine is jammed with debris and not spinning even though water is passing through. Cleaning a stuck flow turbine often resolves E07 without replacing any parts. If the turbine is clean and spins freely, the sensor's electrical signal may have failed.

What Does the E07 Code Mean?

The Bosch flow sensor is a small turbine device installed in the water supply path. As water flows through, the turbine spins and generates pulses that the control board counts to measure water volume. When the turbine is jammed, no pulses are generated, and the board either interprets this as no water flow (E07) or inaccurate volume counting (which can cause E17 overfill). Cleaning the turbine is often overlooked because most DIY guides only mention replacing sensors.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Flow sensor turbine jammed by mineral scale or debris40%
Flow sensor electrical failure24%
Low water pressure causing insufficient turbine rotation22%
Wiring harness damage between sensor and control board14%

Symptoms You May Notice

  • E07 displayed during fill phase
  • Dishwasher not filling despite water supply being on
  • E07 with normal water pressure at the supply tap
  • E07 alternating with 5UC or E17 codes

Can you reset a Bosch dishwasher to clear the E07 code?

After cleaning the turbine or replacing the sensor, hold Start/Reset for 5 seconds and run a test fill cycle to confirm E07 is cleared.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Confirm water supply is fully on

Before diagnosing the sensor, open the cabinet under the sink and confirm the hot water supply valve to the dishwasher is fully open. A partially closed valve can cause insufficient flow to spin the turbine even though some water is entering. Even a valve turned only 80% open can drop the flow rate below the threshold needed for turbine rotation. Turn the valve counterclockwise until fully open - it should not move if already fully open. Run a test cycle to see if E07 clears before proceeding to the sensor.

2

Locate and clean the flow sensor turbine

3

Test flow sensor electrical output

4

Inspect the sensor wiring harness

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Where is the flow sensor on a Bosch dishwasher?
The flow sensor on a Bosch dishwasher is located in the water intake path, typically integrated into or mounted directly adjacent to the inlet valve assembly at the bottom rear of the unit. To access it, you will need to disconnect the water supply hose and remove the lower access panel. The sensor is a small plastic housing with a 3-wire connector and a visible turbine window on the body. On some models it is a separate component from the inlet valve; on others it is built into the valve body.
Can I clean the flow sensor myself?
Yes, and cleaning is often the only fix needed. The turbine inside the flow sensor can become coated in mineral scale from hard water, preventing it from spinning freely. Access the sensor at the inlet valve area, detach it, and soak it in undiluted white vinegar for 30-60 minutes to dissolve mineral deposits. After soaking, spin the turbine manually with a toothpick - it should rotate freely. Rinse thoroughly with clean water before reinstalling. This free fix resolves E07 in a significant number of cases.
I have E07 but my water pressure is normal - what does that mean?
E07 with normal water pressure indicates the turbine is jammed and not spinning even though water is flowing around it. When the turbine is stuck, no pulses are sent to the control board, which then reports no flow detected even though water is present. This is the most common E07 scenario on dishwashers installed in hard-water areas. Cleaning the turbine rather than replacing the entire sensor should be the first step. If cleaning does not restore turbine rotation, the sensor bearing has failed and the assembly needs replacement.
Flow sensor vs inlet valve - which is more likely to fail and cause E07?
The flow sensor turbine jamming is significantly more likely than a complete inlet valve failure in hard-water areas. The inlet valve solenoid failure is more likely to cause E19 (valve actuation fault) or 5UC (no water at all) rather than E07. E07 specifically means water flow is not being detected or measured, which points directly at the flow sensor rather than the valve that opens to allow water in. Always clean the sensor first before considering valve replacement.
How long does flow sensor replacement take?
Replacing the flow sensor on a Bosch dishwasher takes 30-60 minutes for a first-time DIYer. The main time is spent pulling the unit out from the cabinet, disconnecting and reconnecting the water supply hose, and routing the new sensor's wiring correctly. The sensor itself swaps out in about 5 minutes once it is accessible. Budget an additional 15 minutes for running a test cycle and confirming the E07 is cleared before pushing the dishwasher back into the cabinet.
