Error code F02 E01 (or legacy code F21) on a Whirlpool or Maytag washing machine indicates a Long Drain Timeout. When the electronic control board commands the electric drain pump to evacuate the wash tub, the main water level pressure transducer must register an empty tub within 8 minutes. If water remains or if the pressure switch fails to reset, the machine halts the cycle with full soapy water and locks the lid.
Over 80% of F02 E01 service calls are caused by physical debris (coins, hairpins, baby socks, bra underwires) clogging the pump impeller chamber, rather than a permanently destroyed control board.
Step 1: The 30-Second Hard Reset Sequence
Before disassembling any hoses, perform this logic reset to confirm whether the code was triggered by a temporary siphoning glitch:
- Disconnect the washer power cord from the wall outlet.
- Wait a full 60 seconds to allow the central board capacitors to discharge.
- Reconnect the power cord.
- Within 12 seconds of plugging in, open and close the washing machine lid firmly 6 times.
- Press POWER, select Drain & Spin, and press START.
If the pump hums and drains the tub completely, the error was cleared. If the pump hums loudly without pumping, or hums silently and clicks off, proceed to physical inspection.
Step 2: Clearing the Drain Pump Cleanout Trap
Always disconnect electrical power before removing the lower front access panel. Keep towels and a shallow baking tray nearby; standing water will escape when the cleanout filter is opened.
- Use a 1/4″ nut driver to remove the two screws securing the lower front access panel (or tilt the machine rearward and support with wooden blocks).
- Locate the black plastic drain pump housing mounted on the bottom right/left of the base frame.
- Clamp the corrugated black tub-to-pump hose with locking pliers to stop free water flow.
- Unscrew the circular cleanout filter cap counter-clockwise.
- Extract any foreign objects lodged inside the impeller vanes. Check that the plastic impeller blades spin freely with your finger (they should have slight magnetic resistance but must not bind).
Step 3: Multimeter Electrical Resistance Test (12–16 Ohms)
If the impeller chamber is completely clean but the pump refuses to run, the motor coil may be burned out. You can verify pump integrity in under 2 minutes using an ordinary digital multimeter.
| Component / Terminal | Expected OEM Reading | Diagnostic Meaning |
|---|---|---|
| Plaset / Whirlpool Drain Pump Terminals | 12.5 Ω to 16.5 Ω | PASS: Motor windings are intact; check wiring harness or control board relay. |
| Terminal to Ground (Metal Chassis) | Infinite (O.L.) | PASS: No short-to-ground detected. |
| Open Circuit (O.L. / 1) | Over 100k Ω / Infinite | FAIL: Motor coil wire is burned or broken. Pump replacement required. |
| Short Circuit (0.0 Ω) | 0.0 Ω to 2.0 Ω | FAIL: Internal coil winding shorted. Pump replacement required. |

Frequently Asked Questions
Why does my washer hum when F02 E01 appears?
A humming sound indicates the main control board is successfully sending 120V AC to the drain pump motor, but the impeller is physically jammed by a foreign object or the pump bearings have seized. Clearing the cleanout trap usually solves it.
Can a blocked drain hose cause F02 E01?
Yes. If the corrugated discharge hose is pushed deeper than 4.5 inches into the wall standpipe, or if the standpipe height exceeds 96 inches, siphoning or back-pressure will prevent the pump from meeting the 8-minute evacuation deadline.
