Hi Peter, If I understand your question correctly, you are asking what the code "HD" means for your machine. I am unable to find the code "HD", however, here is a list of the codes for these Maytag models, perhaps one looks similar to "HD". Hopefully this answers your question!

Washer displaying code messages
- "LF" (Washer is taking too long to fill)
Check the following:
Are the water inlet hoses kinked or clogged?
Are the water inlet valve screens clear?
Press PAUSE/CANCEL to clear display.
- "Ld" (Washer is taking too long to drain water from the wash tub)
Check the following:
Is the drain hose kinked or clogged?
Is the drain hose installed properly? See "Connect the Drain Hose." Press PAUSE/CANCEL
to clear display.
- "uL" (Unbalanced Load)
If the load is unbalanced, the washer will display this code while running an imbalanced
load correction routine at the end of the wash cycle and before the final spin. If the code
remains and the wash cycle dial is flashing after the recovery routine has stopped, open
lid and redistribute the load. Close lid and press START.
- "oL" (Over Load)
Is the washer overloaded? The washer has attempted to fill and begin the wash cycle. If
the washer is overloaded, it will drain any water and detergent that was added during the
fill. To correct the overload, remove several items and add detergent. Close lid and press
START.
- "Sd" (Suds Detected)
Did you use regular detergent?
Regular or hand-washing detergents are not recommended for this washer. Use only High
Efficiency ("HE") detergent.
Did you add too much detergent?
Always measure detergent. Follow detergent manufacturer's directions.
If excessive suds are detected, the washer will display this code while running a suds
reduction correction routine at the end of the wash cycle. The suds reduction routine
removes extra suds and assures proper rinsing of your garments. If the code remains and
the wash cycle dial is flashing after the recovery routine has stopped, re-select your
desired cycle using cold water. Press START. Do not add detergent.
- "lid" (Lid Opened)
Is the lid open? Close the lid to clear the display. If the lid remains open for more than 10
minutes, water in the wash tub will drain.
- "HC" (Cold and Hot hoses switched)
This code will appear at the end of the wash cycle to indicate that the cold and hot water
inlet hoses are switched. See "Connect the Inlet Hoses."
- "dL" (Door/Lid cannot lock)
Indicates lid is not locked. Check for items caught in the lid keeping it from closing. Press
PAUSE/CANCEL once to clear the code.
- "dU" (Door/Lid cannot unlock)
Is there excessive weight on the lid, such as a basket of laundry? Excessive weight will
keep the lid from unlocking. Press PAUSE/CANCEL once to clear the code.
- "F##" code
Press PAUSE/CANCEL once to clear code. Press START. If code appears again, call for
service.

I have the manual for this machine. Under "Code 21" it says the following:
"F21" (Drain Problem) Select STOP twice to cancel the cycle. Unplug washer or disconnect power. Check the following: Is the drain hose kinked? Is the drain hose frozen? Is the drain hose clogged? Is the drain hose more than 96" (2.4 m) above the floor? Plug in washer or reconnect power. Re-select cycle and press START. If the problem remains, call for service.
For "SUDS" code, the following:
"SUD" (Suds Routine) When excessive suds are detected, a suds routine automatically starts. This routine removes extra suds and assures proper rinsing of your garments. "SUD" is displayed during rinsing to inform you that Suds Routine was activated. Use only HE (High Efficiency) detergents.
Here is some more information that may help you as well:
"F" Codes other than F20, F21 and F22 Select STOP twice to cancel the cycle. Select DRAIN & SPIN if there is excessive water in the washer. Re-select cycle and press START. If the problem remains, call for service.
I hope this is of some help to you, Please rate and comment, Thank You
Joe

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.

F/02 Long Drain
If the drain time exceeds 8 minutes, the water valves are turned off and "F/02" is flashed.
NOTE: After 4 minutes the "Sud" error will be displayed, then 4 minutes later the F02 error code will be displayed.

Press PAUSE/CANCEL twice to clear the display.

• Check the drain hose and make sure it is not plugged or kinked.
• Check the electrical connections at the pump and make sure the pump is running.
• Check the drain pump filter for foreign objects.
• If the above does not correct the problem, replace the pump.

apply a small amount of cooking oil imside tub ,, must use only HE deteregent if you are ,,, maybe too much

I own a HE3 kenmore elite for 4 years now and the troubleshooting codes are: SUD When excessive suds are detected, a suds routine automatically starts. This causes the cycle to go longer to remove the excess suds. Reduce detergent amounts or use HE detergent. The F02 error I had with mine and it is a drain problem. Book says check the hose for kinks, clogged or is it more than 96 inches above the floor. On mine it was the fan pump on the forward motor that drains the washer. It was worn and not pushing out the water fast enough. You will hear a high pitched whine at the front bottom of the washer if this is bad. To reset the washer from the F02 error, select pause/cancel twice to cancel the cycle. Unplug washer or dissconnect power. good luck
