What causes Whirlpool Dryer F01 / F-01 / F1 E1?

A failed main control board (machine control electronics), which is the repair Whirlpool's tech sheets list for F-01. A power surge, brownout or outage that left the control in a fault state; a power reset often clears this. On newer F1 E1 models, no voltage detected at the heater relay, often from a wire that has come loose at the heater element or at the relays on the control board. Corrosion or a poorly seated connector on the control harness, which Whirlpool's service guides list as a common cause of a control not working. A tripped breaker or blown fuse on one leg of an electric dryer's 240V supply.

How do I fix Whirlpool Dryer F01 / F-01 / F1 E1?

Turn the dryer off at the circuit breaker (electric dryers use a double breaker) or unplug it, and leave it off for 5 minutes, as Whirlpool's product help recommends. Turn the power back on, start a Timed Dry cycle, and watch the dryer for at least one minute to see whether F01 comes back. Check your home's breaker panel and fuses. If one side of the dryer's breaker has tripped or a fuse is blown, reset or replace it once. Make sure the dryer's power cord is fully plugged in and the outlet isn't loose or scorched. If the outlet looks damaged, stop and have an electrician look at it. If you have a Whirlpool compact heat pump dryer, touch and hold Power for at least 3 seconds to clear the code, then restart and watch it for 5 minutes. Write down your model number (on a label inside the door opening or on the back) before calling for service or ordering a control board, since boards are model-specific.

When should I call a pro for Whirlpool Dryer F01 / F-01 / F1 E1?

F01 or F1 E1 comes back right after a 5-minute power reset. Whirlpool says to contact them or schedule service at that point. Replacing the main control board. Boards are sensitive to static, so Whirlpool's sheets call for an anti-static wrist strap and handling the board by its edges. Checking voltage at the control, the heater relay or the heater element. That's live 240V work and needs a qualified technician. The breaker trips again after you reset it, or you smell burning or see scorched wiring. Stop using the dryer. The dryer is still under warranty. Opening it up yourself may affect coverage, so book service instead.

Whirlpool Dryer F01 (F-01 / F1 E1): Main Control Failure (Meaning, Causes, Fixes)

Q: What does Whirlpool Dryer F01 / F-01 / F1 E1 mean?

F01 on a Whirlpool dryer means the dryer's main electronic control has detected a fault in itself. Whirlpool's first fix is a 5-minute power reset at the breaker. If F01 comes right back, Whirlpool's service sheets call for replacing the main control board, which is a job for a technician or a confident DIYer. Whirlpool's service tech sheets for its electronic dryers (including many Duet and Cabrio models) list F-01 as a Primary Control Failure: the dryer's machine control electronics have flagged an internal problem, and the recommended repair is to replace the machine control electronics. Newer Whirlpool and Maytag dryers show the same family of fault as F1 E1, alternating F1 and E1 on the display. On those models the tech sheets call it a Main Control (ACU) fault and say it can also mean no voltage was detected at the heater relay, so loose wires at the heater or the relays on the control are checked before the board is replaced. Whirlpool's product help says any code that alternates between F# and E# means the control has found a problem that needs service. On Whirlpool compact heat pump dryers, F01 through F04 are cleared by holding the Power button for 3 seconds and restarting.
