How to Troubleshoot a Maytag Epic Washer Front Loader Tip Call Maytag for service if any of these procedures doesn't clear the code on the washer display.

Warning Maytag makes several models in the Epic series and operating instructions vary. For model-specific troubleshooting instructions defer to the user manual that came with your machine or contact Maytag support.

Each model in the Maytag's Epic automatic clothes washer series has a computerized processing unit that displays error codes on a digital screen when something goes wrong with the washer. These codes help Maytag service technicians diagnose the unit. If you know the codes, you can troubleshoot the problem yourself, rather than request a service call, possibly fixing the issue yourself and saving you some money in the process.

2.Remove the clothes from washer, carefully examining them for damage from the excess suds issues.

"LF" on display (Long Fill - no water or insufficient water supply) Press POWER/CANCEL to cancel the cycle. Unplug washer or disconnect power.
Plug in washer or reconnect power. Re-select cycle and press START/PAUSE. "F9E1" on display (Drain Problem) Press POWER/CANCEL to cancel the cycle. Unplug washer or disconnect power.
Plug in washer or reconnect power. Re-select cycle and press START/PAUSE. "SD" on display (Suds Routine) When excessive suds are detected, a suds routine automatically starts. This routine removes extra suds and assures proper rinsing of your garments. "SD" is displayed during rinsing and at the end of the cycle to inform you that the Suds Routine was activated. Use only HE (High Efficiency) detergents. "F--E--" Variables (Washer Problem) Press POWER/CANCEL to cancel the cycle. Select RINSE, DRAIN & SPIN if there is excessive water in the washer. Re-select cycle and press START/PAUSE.

My Kenmore washer does that too, it means there is too much suds in the tub so the machine will go thru a rinse type cycle to remove the excess suds. It should then go back to normal washing.

The "rl" (remove load) error code appears when you are running the "Clean Washer" cycle. You must not have a load of clothes in the washer during this cycle. Remove the clothes from the drum, and restart the cycle. The "Sud" error indicates that the detergent is over-sudsing. The Duet washer automatically combats this by reducing the amount of suds in the washing machine. Let the washer finish the suds-reduction steps. Use less detergent during the next wash cycle.

Hi Jamie: After checking all of this and if it still dont work you will need to put in a new control board.

Plug cord into live electrical outlet. Check for proper voltage.
Check fuse or reset circuit breaker.
Push any key to turn ON the clothes washer and press the Rotary Cycle Selector knob to start the clothes washer.
Close door and push the Rotary Cycle Selector knob to start the clothes washer.
Check to see if the clothes washer is in a pause, soak or suds period in the cycle. Wait briefly and it may start. If washer is in suds period, SU and DS will display alternately, instead of the time remaining.
Check for restricted drain system. If there is an electrical problem in the drain system, ND error will occur after 15 minutes.
Check water supply.
Check the line screen and water valve screen.
Check for loose connections at machine control board terminal connections
Replace machine control board.

What does the Sd code mean?

This code indicates that excessive detergent suds occurred during the cycle. The washer will not be able to spin out water with the excess suds. When "Sd" is displayed, the washer automatically extends the rinse time to remove the excess suds. During this time, the washer pauses the wash action and adds water for additional rinsing. This pause allows the bubbles in the suds to break. This process is necessary and may occur several times to eliminate the suds.

Concentrated detergents labeled 2x and higher will require a small amount of detergent based on load size. Always follow the manufacturer's recommendations.

Use only HE High Efficiency detergent for BravosTM washers.

Is "Sd" displayed and the wash cycle dial is flashing?

This indicates the washer was not able to clear all the excess suds from the washer. Re-select your desired cycle using cold water. Press Start/Pause. Do not add detergent.

Is "Sd" displayed and the wash cycle dial is not flashing?

If "Sd" is displayed and the wash cycle dial is not flashing, allow the machine to continue running, even if it appears that nothing is happening. When "Sd" is displayed, the washer automatically extends the rinse time to remove the excess suds. During this time, the wash action will pause to allow the bubbles in the suds to break, and the washer will add water for better rinsing. This rinsing process is necessary and may occur several times to eliminate the suds.

Is the drain hose kinked or clogged?

Make sure that the drain hose is not kinked or clogged. Straighten the hose for adequate water flow. Remove any blockage from the drain hose, drainpipe or utility sink. Use the U-shaped drain hose form on the drain hose, and secure the drain hose.

To remove the error display, press Power/Cancel or Pause/Cancel once.

If Power/Cancel or Pause/Cancel does not work:

1. Unplug the washer or disconnect the power for one minute.
2. Plug in the washer or reconnect the power.
3. Re-select the cycle and press Start/Pause.

NOTE: If the error remains on the display, and all of the other questions above have been checked, call for service.

to much detergent...with theses unit you must use he or low suddsing detergent..take half the wet soapy clothes out then start unit..sud level must fall...

The SUDS message relates to overdose of detergent detected during the Wash Cycle. This may signify a bad pump, an extra heavy load, excessive detergent or excessive suds. If too much detergent was used, run the washer through a Rinse/Spin cycle, then a Normal cycle, without adding any detergent. This should clear the unit of the excess detergent. Check the drain hose and make sure it is not plugged or kinked. Good luck!
