Miele Dishwasher Error Code F18 and F19
Miele dishwashers are celebrated for their reliability and advanced technology. However, error codes like F18 and F19 can occasionally appear, signaling problems related to the flow meter. These codes indicate that your dishwasher is experiencing issues with water flow — either insufficient water supply or a malfunctioning flow meter sensor.
What Do Error Codes F18 and F19 Mean?
The flow meter monitors the volume and rate of water entering your dishwasher through the inlet valve. When it detects irregularities, such as low water flow or sensor failure, the dishwasher will display error codes F18 or F19 to alert you to the problem. Left unresolved, these issues can affect cleaning performance and potentially cause damage.
Common Causes of Flow Meter Errors in Miele Dishwashers
-
Clogged or Damaged Inlet Valve: Mineral deposits, rust, or debris can block the inlet valve, reducing water flow.
-
Faulty Circulation Pump: A malfunctioning pump may fail to push water properly through the spray arms.
-
Defective Heat Pressure Switch: Issues with this switch can disrupt normal water flow detection.
How to Troubleshoot and Fix Miele Dishwasher Error Codes F18 and F19
1. Inspect and Clean the Inlet Valve
The inlet valve controls water entering your dishwasher. Check for signs of blockage or damage caused by limescale or debris buildup. Cleaning or replacing a faulty valve often restores proper water flow and resolves the error.
2. Test the Circulation Pump
The circulation pump moves water through the dishwasher’s spray arms. Use a multimeter to check the pump’s electrical functionality. If the pump shows signs of wear or failure, replacing it can fix flow issues and improve dishwasher performance.
3. Check the Heat Pressure Switch
The heat pressure switch helps regulate water flow and temperature. Ensure it operates correctly; a defective switch may trigger flow meter errors. If necessary, have a professional inspect and replace this component.
When to Call a Professional Technician
If after performing these checks the error codes persist, or if you’re unsure how to proceed safely, contact a certified appliance repair technician. They have the expertise to diagnose complex flow meter problems and perform precise repairs to get your Miele dishwasher running smoothly again.
