Whirlpool Dishwasher Error Code F8 E1: How to Fix It

The Logic Verdict

My Take: The video author notes: “This error code indicates a problem with the water level in the dishwasher… inspect the pressure switch grill to ensure it’s not blocked.” Based on this, I recommend inspecting the Filters and Pressure Switch (or Optical Water Indicator) first.

What It Means

The F8 E1 code indicates a Water Level Issue (often “No Water” or “Slow Drain” depending on the specific model). The dishwasher detects that the water level is not correct for the current cycle stage.

Common Causes

1. Blocked Filters: Food debris clogging the sump prevents water from reaching the sensor.
2. Dirty Optical Water Indicator (OWI): The sensor that detects water clarity and level is covered in grime.
3. Faulty Pressure Switch: The switch that monitors water level is stuck or broken.
4. Water Supply Issue: The inlet valve is not opening fully (if “No Water”).

Step-by-Step Fix

1. Clean the Filters:
   • Remove the bottom rack.
   • Remove the cylindrical filter and the flat screen filter.
   • Clean them thoroughly.
2. Clean the OWI Sensor:
   • Locate the Optical Water Indicator (usually a small clear plastic dome or probe in the sump area).
   • Wipe it clean with a soft cloth and mild detergent.
3. Inspect Pressure Switch (If Equipped):
   • Check the pressure switch grill (a small opening in the sump) for blockage.
   • Use a blunt object to gently clear any debris.
4. Check Water Supply:
   • Ensure the water supply valve is fully open.
   • Check the inlet hose for kinks.
