WHIRLPOOL HC

Whirlpool Washing Machine Error HC: Hot and Cold Inlet Hoses Reversed

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washer has detected that hot water is entering the cold water inlet — the hot and cold supply hoses were swapped at installation. This applies to top-load HE models. The washer will not operate correctly with reversed hoses.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Whirlpool washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Hot and cold hoses swapped at installation — the most common cause after a new washer installation or hose replacement

Estimated time for safe first checks: 10–15 min.

Step-by-Step DIY Fix Guide

  1. SAFETY: Turn off both water supply valves behind the washer, then unplug the washer.
  2. Allow the hoses to cool — the incorrectly connected hot hose will be warm.
  3. Place a towel on the floor and disconnect both inlet hoses from the back of the washer.
  4. Reconnect correctly: the hose from the COLD supply (blue label) goes to the COLD inlet port on the washer, and the HOT supply (red label) goes to the HOT inlet port.
  5. Tighten each connection firmly by hand, then a quarter-turn with pliers.
  6. Turn the supply valves back on and check both connections for drips.
  7. Plug the washer in and run a test cycle — HC should not return.

If it's still not filling correctly

  • If normal household water flow looks good but the code returns, the inlet-valve or fill-sensing path becomes more likely.
  • HC persists after hoses are correctly connected and supply temperatures are confirmed
