Maytag Washer LF Error Code: Long Fill - Water Supply Too Slow
Quick Answer
Maytag LF (Long Fill) is one of the most straightforward washer errors to diagnose because it is almost always a water supply issue external to the machine. The most commonly missed cause: both hot AND cold water supply valves must be fully open even if you only wash in cold water. Maytag washers check both supply lines during fill, and a closed hot valve causes LF even on cold-only cycles.
Maytag LF (Long Fill) is one of the most straightforward washer errors to diagnose because it is almost always a water supply issue external to the machine. The most commonly missed cause: both hot AND cold water supply valves must be fully open even if you only wash in cold water. Maytag washers check both supply lines during fill, and a closed hot valve causes LF even on cold-only cycles. The second most common cause is clogged inlet hose screens - small mesh filters inside the hose connections at the back of the washer that catch sediment. These screens are not visible without disconnecting the hoses. On Maytag Bravos models specifically, LF can also be triggered by a kinked pressure switch hose that prevents the board from detecting the rising water level accurately.
What Does the LF Code Mean?
LF = water fills too slowly. Check that BOTH hot AND cold valves are open (both needed even for cold wash). Then check inlet hose screens for sediment. Also check pressure switch hose.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Symptoms You May Notice
- LF on display
- Washer takes very long to fill
- Water trickles in slowly
- Washer starts but stops during fill phase
- Hot water side fills but cold does not (or vice versa)
Can you reset a Maytag washer to clear the LF code?
Press Pause/Cancel twice, then Power. LF clears once the washer successfully fills to the target level within the time limit.
