What FAE4 means

FAE4, which may also display as F10E4, is a diverter valve error on Whirlpool built-in dishwashers such as the WDT730PAHZ. The diverter directs water to the correct spray arms during the cycle, so when the control cannot confirm its position, it stops and shows the code. Owners may notice dishes washed unevenly, noise at the start of a cycle, or a cycle that will not continue.

Common causes of FAE4

  • Diverter valve and its motor or connection
  • Wiring between the diverter and the control
  • Control board output for the diverter
  • A passing error cleared by a power cycle
✓ One safe check you can try

1. Power-cycle it: disconnect the dishwasher from the outlet for 30 seconds and reconnect. If it is hard-wired, switch the breaker off for 30 seconds and back on. 2. Close the door firmly and start a cycle. 3. If FAE4 or F10E4 appears again, stop and book service.

! Why to stop there
  • The diverter sits inside the wash system, where we have to look at it directly
  • Position feedback and wiring can fail separately from the valve itself
  • We test the diverter and its circuit, and give a written price before any part is ordered
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

FAE4FAE4 questions
Are FAE4 and F10E4 the same code?

Yes. The dishwasher may show either form for a diverter valve error, depending on the display. The checks and the repair path are the same for both.

What does the diverter valve do?

It sends water to the right spray arms at the right time. If it sticks or cannot report its position, the control stops the cycle and displays the code.

Is FAE4 related to FAE5?

They are neighbors. FAE4 is a diverter valve error, FAE5 is a diverter leak. Because both involve the diverter, we inspect for leaks and the circuit on the same visit.
