What F8E2 means

F8E2 on a Whirlpool built-in dishwasher such as the WDT750SAHZ is listed as a fill valve electrical error. The fill valve is the electric gate that lets water into the tub, and the control has found a problem in the circuit that operates it. You will see the code, and the dishwasher may fill poorly, not fill at all, or stop the cycle. Unlike F8E1, the water supply is not the first suspect here, the valve circuit is.

Common causes of F8E2

  • Fill valve coil and its electrical connection
  • Wiring between the valve and the control
  • Control board output to the valve
  • A one-off error cleared by a power cycle
✓ One safe check you can try

1. Look at the drip tray area under the dishwasher door for dampness, and check that the inlet valve connection is not leaking. Do not take anything apart. 2. Cycle the power: unplug for 30 seconds and plug back in, or switch the breaker off for 30 seconds if hard-wired. 3. Start a normal cycle. 4. If F8E2 returns, schedule service.

! Why to stop there
  • Whether the valve itself or the wiring to it is the problem cannot be seen from outside
  • A slow drip at the inlet connection can sit alongside an electrical problem
  • We test the valve circuit, then give a written price before replacing anything
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.

F8E2F8E2 questions
Does F8E2 mean my water supply is off?

No. A closed supply tends to give F8E1 or H20. F8E2 is about the electrical side of the fill valve, so the supply is worth a glance, but the circuit is the focus.

Is a leak possible with F8E2?

It can be. That is why you should check the inlet valve connection for dampness. If you find water, shut the supply off, keep the dishwasher unplugged, and call us.

What will the visit involve?

We test the valve coil and the wiring to it, then the control output. You get the written price before any part is ordered, and the repair carries a 30-day workmanship warranty.
