Understanding the KitchenAid Dishwasher F7E1 Error Code

This guide will walk you through several steps to diagnose and potentially fix the problem.

KitchenAid dishwasher F7E1 error code: Possible Causes

  • Loose or damaged cables connecting the VSM motor and control board.
  • Faulty connectors or windings in the VSM motor or control board.
  • Damaged wires or loose connections in the VSM motor’s power and communication cables.
  • Clogged spray arms or a fin filter are hindering the VSM motor’s operation.
  • A faulty VSM motor is also known as a circulation pump or a wash pump itself.
  • In rare cases, a malfunctioning main control board.

KitchenAid dishwasher F7E1 error code: Troubleshooting Steps

  1. Inspect connections.
    • Check the cable connecting the VSM motor to the control board for any loose connections or visible damage to the wires or connectors. Secure any loose connections and replace damaged components.
  2. Examine connectors and windings.
    • Carefully look for signs of corrosion, short circuits, or other damage on the connectors and windings of the VSM motor and control board. Clean the connectors if necessary, and replace any damaged parts.
  3. Verify VSM power and communication cables.
    • Inspect the power and communication cables connected to the VSM board for any cuts, breaks, or loose connections. Replace damaged wires and secure loose connections to ensure proper function.
  4. Clean the spray arms and filter.
    • Clogged spray arms or a blocked filter can affect the VSM motor’s performance. Clean the spray arms thoroughly and ensure the fine filter is free of debris and buildup.
  5. Test VSM motor “wash pump” resistance (for advanced users).
    • This step requires a multimeter. Disconnect the VSM motor from the control board and measure the resistance across its terminals. Compare the reading to the values specified in the table below. A significant difference might indicate a faulty motor requiring replacement.
Electric Part NameOhmic Value
Wash Pump (Three Phase): VSM Model~52 Ω
Wash Pump (Single Phase): Main Coil~8 Ω
Wash Pump (Single Phase): Aux Coil~11 Ω
Wash Pump (Single-Phase): Capacitor20 μF

If the F7E1 error code persists after trying these steps, consult a qualified appliance repair technician. They can diagnose the issue more thoroughly and potentially replace the VSM motor or main control board if necessary.

By the way,

  • For steps involving electrical components, ensure the dishwasher is unplugged for safety.
  • Refer to your dishwasher’s repair manual for specific disassembly and troubleshooting instructions for your model.

By following these steps, you should be able to identify and potentially fix the cause of the F7E1 error code in your KitchenAid dishwasher.
