Whirlpool Dishwasher Error Code F9 E1 — Diverter Error
What this means
The F9 E1 error indicates the diverter motor (which directs water between the upper and lower spray arms) is stuck or not responding. Dishes on one rack may not be getting cleaned.
Step-by-step fix
3 stepsPower cycle the dishwasher
Turn off the breaker for 5 minutes and turn it back on. Run a cycle and see if both spray arms are functioning.
A temporary motor jam can sometimes be cleared with a power reset.
Check the spray arms
Remove and inspect both spray arms for clogs in the water holes. Food debris can block the holes and reduce water pressure, mimicking a diverter issue.
Use a toothpick to clear clogged spray arm holes.
Listen for the diverter motor
During a cycle, listen near the bottom of the dishwasher for a clicking or humming sound. This is the diverter motor switching between spray arms.
If there's no sound from the diverter during the cycle, the motor likely needs replacement.
When to call a professional
The diverter motor is located inside the sump assembly at the bottom of the dishwasher. Replacement requires significant disassembly.
