Bosch SHPM88Z75N E14 Error Code | E14 Flow Meter Failure

Error e14 on Bosch shpm88z75n: Flow meter failure — water inlet flow sensor not detecting or measuring water co. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. ## What Does E14 Mean on a Bosch SHPM88Z75N? Your Bosch dishwasher is displaying an E14 error code, which indicates a fault with the flow meter — a sensor in the water inlet system that measures how much water is entering the dishwasher. The flow meter uses a rotating impeller to count water volume and reports to the control board. E14 appears when the sensor stops functioning, the impeller is stuck, or the control board is not receiving a valid flow count. Without accurate flow measurement, the dishwasher cannot control fill volume. ## Fault Details | Field | Value | |-------|-------| | Error Code | E14 | | Appliance | Bosch SHPM88Z75N 800 Series Plus Top Control Dishwasher | | Fault Type | Flow meter failure | | Severity | Medium | | User Serviceable | No — professional service recommended | | Applicable Models | SHPM88Z75N, SHP78CM5N, SHPM65Z55N | ## Common Causes - Flow meter sensor element failure — sensor signal not reaching the control board

  • Flow meter impeller jammed by mineral deposits, debris, or scale build-up
  • Water supply pressure too low (below 0.06 MPa / 8 PSI minimum) — impeller not spinning
  • Wiring harness to the flow meter damaged or connector loose
  • Water inlet valve partially or fully blocked, reducing flow below sensor detection threshold
  • Control board flow meter input circuit failure ## Step-by-Step Troubleshooting | Step | Action | What To Do | Expected Result | |------|--------|------------|-----------------| | 1 | Check the water supply | Verify the water supply valve under the sink is fully open. Check your home’s main water pressure — Bosch dishwashers require a minimum of 0.06 MPa (8 PSI). Test by running a kitchen faucet — good flow at the faucet confirms adequate supply pressure | Strong water flow at the faucet — issue is specific to the dishwasher | | 2 | Inspect the inlet hose for kinks | Pull the dishwasher slightly away from the cabinet and inspect the water inlet hose at the back. Straighten any kinks and ensure the hose is not pinched by the cabinet | Hose is straight and unobstructed | | 3 | Reset the dishwasher | Turn off power at the circuit breaker for 30 seconds. Restore power and run a short cycle to check if E14 clears. Sometimes a one-time sensor glitch clears with a reset | E14 does not return after reset — transient flow sensor fault | | 4 | Inspect the flow meter for mineral deposits | A Bosch technician can access and inspect the flow meter assembly for calcium scale on the impeller. If your area has hard water and you have not been using Bosch dishwasher salt and cleaner regularly, scale build-up is a likely cause | Clean impeller confirmed or scale build-up identified — cleaning or replacement needed | | 5 | Contact Bosch service for flow meter replacement | Flow meter replacement requires accessing the interior plumbing components. Contact Bosch customer service at 1-800-944-2904 or a certified Bosch service partner for professional repair | E14 resolved after flow meter replacement | ## Frequently Asked Questions ### Can low water pressure cause E14? Yes. If your home water pressure is below the minimum required by Bosch (8 PSI), the flow meter impeller may not spin fast enough to register flow. This is more common when multiple water-using appliances run simultaneously. Check if E14 appears only when other taps or appliances are in use. ### Does hard water cause E14? Hard water mineral deposits (calcium and magnesium scale) are a leading cause of E14. Scale can coat the flow meter impeller and prevent it from spinning freely. Bosch recommends using dishwasher salt in the built-in water softener system to prevent scale throughout the plumbing and sensors. ### What is the flow meter and why does it matter? The flow meter is a small sensor in the water inlet path that counts how many liters of water enter the dishwasher. The control board uses this data to know when to stop filling. Without it, the dishwasher cannot accurately fill to the correct water level — too little water means poor washing; too much could overflow. ### How long does flow meter replacement take? A trained Bosch technician can typically replace the flow meter in 30–60 minutes. The part is located in the inlet water path and requires partial disassembly of the dishwasher front or base panel to access. --- Source: Bosch 800 Series Plus Top Control Dishwasher service documentation. Last Updated: March 2026 ### Is it safe to keep using my Bosch shpm88z75n with error e14? If error e14 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the dishwasher with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error e14 on a Bosch shpm88z75n? Repair costs for error e14 on the Bosch shpm88z75n dishwasher depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Bosch-authorized service provider for an accurate estimate based on your specific situation. ### What does error code e14 mean on a Bosch dishwasher? Error code e14 on Bosch dishwasher models indicates Flow meter failure — water inlet flow sensor not detecting or measuring water correctly. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed. Refer to the troubleshooting steps above for guidance on resolving this issue. ### Is it safe to keep using my Bosch shpm88z75n with error e14?
