The washer displays "HC" or "HC error"; water temperature seems incorrect (hot when cold is selected or vice versa).

Safety: Turn off both water supply valves before disconnecting hoses.

• Verify hose connections: Check that the hose connected to the hot faucet is attached to the hot inlet on the washer (usually marked red or "H"), and the cold to the cold inlet.
• Swap hoses if reversed: If they are reversed, switch them at the back of the washer and tighten securely.
• Test cycle: Run a warm wash and confirm that the washer fills with properly mixed water.
