What does the dL/dU code mean?
When your Maytag Washer displays dL/dU, the self-diagnostic system has detected a fault requiring attention. A single power cycle that clears the code is not a reliable fix if the underlying cause has not been addressed.
Common causes
Component failure
A worn or failed internal part — motor, pump, sensor, or control board.
Blockage or restriction
Debris or mineral buildup in filters, hoses, or drain paths.
Wiring issue
Vibration over time can loosen harness connectors, causing intermittent faults.
Control board fault
The main board may misread sensor signals and generate a false error.
Installation issue
Improper leveling, restricted airflow, or incorrect water supply pressure.
Step-by-step troubleshooting
01
Power cycle
Unplug the unit from the wall for 60 seconds. Plug back in and run a test cycle.
02
Inspect filters
Locate, remove, rinse, and reinstall the filter or trap for your model.
03
Check hoses
Look for kinks, blockages, or loose fittings in drain and inlet hoses.
04
Verify installation
Confirm the appliance is level and has adequate airflow clearance.
05
Run diagnostics
Consult your owner's manual for the built-in diagnostic mode key sequence.
When to call a professional
If dL/dU returns after the steps above, a component has likely failed. Continuing to run the appliance may cause secondary damage. Our technicians carry common Maytag Washer parts on every vehicle — most repairs are completed in one visit.
