Why Is My Washing Machine Not Draining?
A washing machine that won't drain is almost always a clog, a kinked hose, or a faulty drain pump. Here's how to find out which and fix it.
Short answer: F5 (sometimes shown as F5 E2) means the washer's door lock mechanism isn't confirming a secure lock. It's usually an obstruction, worn latch, or a lock switch that needs a reset — not a control-board failure.
F5 is a lock-confirmation fault, not necessarily a broken latch — the fastest safe check is whether the door produces a distinct click when closed firmly.
| What you notice | Likely direction | Safe next check |
|---|---|---|
| Door looks shut but no click is felt or heard | Obstruction or residue in the door strike | Clean the strike area, then reclose firmly |
| Click sounds normal, error still appears | Possible sensor issue rather than a latch problem | Power-cycle first — this clears many sensor-level faults before a part is actually at fault |
| Lock light flashes, never turns solid | Lock switch not confirming, even after cleaning | Treat this as a switch/motor issue rather than more cleaning |
| Error appeared right after a power flicker mid-cycle | Transient fault during the lock/unlock stage | A single reset is likely to resolve this specific pattern |
What a successful reset actually tells you: if cleaning the strike and power-cycling makes the lock light turn solid on the very next cycle, the fault was transient and no part is likely bad. What recurrence tells you: if F5 comes back within the same load, or the lock light never goes solid even once, the reset didn't fix the underlying cause — treat it as a switch/motor issue at that point rather than repeating the cleaning step again.
Clear obstructions and clean the strike area
Wipe down the door strike and surrounding gasket to remove any residue or debris preventing a full latch.
Power-cycle the machine
Unplug it (or switch off the breaker) for a full 60 seconds, then restore power — this clears many transient lock-sensor errors.
Test the door lock
Close the door and start a short cycle, watching for the lock indicator to turn solid rather than flashing.
Recheck alignment if the error returns
If the error repeats, examine whether the door sits flush and level in its frame; a sagging door may need hinge adjustment.
1. Obstruction in the door strike
A stray sock, small item, or buildup of detergent residue in the door strike area can prevent the latch from fully seating.
2. Worn or misaligned door latch
Repeated slamming or years of use can wear the latch mechanism so it no longer engages the lock switch reliably.
3. Failed door lock switch/motor
The small motorized lock assembly itself can fail electrically, which typically needs professional replacement.
4. Power interruption mid-cycle
A brief power flicker during the lock or unlock stage can leave the system in a confused state that clears with a reset.
Yes — different display formats show the same door-lock fault depending on the model generation.
No — the door lock is a safety feature that prevents the drum from spinning with the door open, so the machine won't run a cycle without it.
It can, if the outage happens during the lock or unlock stage. A simple power-cycle reset often clears this specific case.
Safety warning
The door lock is a safety interlock, not just a convenience feature. Never attempt to defeat, tape over, or manually trigger the lock switch to force a cycle to start.Home Solutions Editorial Team

A washing machine that won't drain is almost always a clog, a kinked hose, or a faulty drain pump. Here's how to find out which and fix it.
The Whirlpool F1 code points to a control board communication fault — usually cleared with a power reset, but a recurring F1 needs board service.
The Maytag F5 E3 code points to a door lock fault on front-load washers — the machine can't confirm the door has locked securely before starting.
The Bosch E18 code indicates the washer can't drain within its expected time — a clogged pump filter is the most common and easiest-to-fix cause.
