Dishwasher displays E17; often associated with low water pressure or slow filling.

Safety first: Turn off power and water before disconnecting hoses.

• Check shutoff valve: Ensure the under-sink dishwasher shutoff valve is fully open.
• Measure pressure: If possible, use a pressure gauge at a nearby faucet to confirm adequate water pressure (typically 20–120 psi).
• Clean inlet screen: Disconnect the inlet hose from the water inlet valve and clean the screen filter thoroughly.
• Test valve coil: Use a multimeter to check the valve coil for proper resistance. Replace the valve if the coil is weak or open.
• Run test cycle: After reassembly, run a quick cycle to verify that filling is normal and E17 does not recur.
