Whirlpool washer — Error Code F02
Long drain fault: water is not draining from the tub fast enough.
What it means
The F02 error code on a Whirlpool washer indicates a Long Drain fault. Specifically, the Central Control Unit (CCU) has energized the drain pump, but the analog pressure sensor (water level switch) reports that the water level has not dropped below the empty threshold within a predetermined time—typically 8 minutes. When the CCU detects this timeout, it immediately halts the cycle, shuts off the pump to prevent motor burnout, and flashes F02. This is primarily a mechanical flow issue, not an electronic glitch. The system relies on a clear path from the tub to the standpipe, a functional drain pump impeller, and accurate readings from the pressure switch via the air dome hose. If any of these fail, the CCU flags the F02 error.
Likely Causes
- 1 Clogged Drain Pump Filter (Coin Trap)Debris like coins, lint, or small socks can bypass the tub and jam the pump filter, severely restricting water flow to the pump impeller.
- 2 Faulty Drain Pump MotorThe pump motor windings may be open or the impeller sheared off. If the pump receives 120VAC from the CCU but doesn't spin or just hums loudly, it has failed.
- 3 Obstructed Drain Hose or StandpipeA kinked external drain hose or a clogged house standpipe will prevent the pump from pushing water out, triggering the 8-minute timeout.
- 4 Blocked Air Dome or Faulty Pressure SwitchGunk in the air dome hose traps pressure, tricking the pressure switch into telling the CCU the tub is still full even if it actually drained.
- 5 Wiring Harness or CCU FailureLoose connections at the drain pump terminals or a failed relay on the Central Control Unit failing to send voltage to the pump.
How to clear / reset
To temporarily clear the F02 error code, press the Pause/Cancel button twice. This will reset the display. You can also perform a hard reset by unplugging the washer from the wall for 1 to 2 minutes to clear the CCU logic. However, because F02 is a hard fault triggered by a physical drainage issue, the code will immediately return on the next cycle if the water cannot exit the tub. To permanently clear it, you must resolve the root blockage or replace the faulty drain pump.

When to call a pro
Call a professional if you have cleared the accessible drain pump filter (coin trap) and the washer still refuses to drain. Testing the drain pump requires a multimeter to check for 120VAC from the CCU and measuring the motor windings for continuity. If the pump is receiving voltage but not running, or if the CCU is failing to send voltage entirely, professional diagnostics are required. Axis Appliance Repair offers a $90 diagnostic (waived if you proceed with the repair) and backs all work with a 1-year parts and labor warranty.
FAQs
How much does it cost to fix an F02 error?
If it's just a clogged filter, you can clean it for free. If the drain pump needs replacement, expect professional repairs to range from $180 to $280 including parts and labor.
Can I fix the F02 code myself?
Yes, if the issue is a clogged coin trap. Most front-load Whirlpool washers have a lower access panel you can remove to unscrew the pump filter and clear out debris. Have towels ready for the water.
Will the F02 error clear itself?
No. The CCU will remember the fault until the display is manually reset (Pause/Cancel twice) and the physical drainage issue is fixed.
How long does it take to replace a Whirlpool drain pump?
A trained technician can typically test the circuit, remove the old pump, and install a new OEM drain pump in 30 to 45 minutes.
Will it damage my washer to keep trying to run it with an F02 code?
Yes. Repeatedly forcing the cycle to restart when the drain path is blocked can overheat and permanently burn out the drain pump motor, or potentially damage the CCU relays.
