Not getting enough water

"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.

Could be several reasons:
- Selected the "Night cycle" program (means standing with the drum full of water, reason: too much noise in the spin cycle)
- Set to the "Rinse hold" (means standing with the drum full of water, reason: wrinkles on the clothes)

According to your description I think that this is not a failure otherwise error E20 will be appears on display.

Once the washing programme has come to an end, END illuminates on the programme progress display.
If RINSE HOLD was selected, the display beside the START/ PAUSE button flashes.
1. After a rinse hold, the water must first be pumped out:
- Either press the START/PAUSE button (the water is pumped out and the washing is spun according to the completed programme;
After the START/PAUSE button is pressed again, the spin speed can still also be changed during spinning), or
- Turn the programme selector to PUMP OUT and press the START/PAUSE button (the water is pumped out without spinning),or
- Turn the programme selector to SPIN or SHORT SPIN and press theSTART/PAUSE button (the water is pumped out and the washing is spun or gently spun).
At the end of this programme step, the END indicator will illuminate.
2. Open the door.
As soon as the DOOR indicator lights up green, the door can be opened.

In the rinse cycle it will use cold only to rinse with.
You need to see how fast the water is going into the machine on rinse
Things that can effect slow fill, low water pressure, Faulty cold valve
water hose & valve filters clogged, Kinked hose

Either you don't have enough water pressure, or the screen filter in the water lines that connect to the machine are clogged.

This sounds like a hard water deposit problem.
Check your water inlet valve for a screen and see if its clogged. Also it may just be a water valve/solenoid problem. As in, it's too crusted up to float up and down.
Some models have a water fill timer, while others use a water fill/pressure switch. This may also bear inspection.
The beep you hear during your cycle is indicating that your water level is too low to cover the heating element, which can cause cracking and lead to a short.

Turn timer to rinse cycle. let fill up and agitate. when it stops agitating it should pause then start to pump water out. After about 2 minutes it should pause for 3-5 seconds then start again and spin. If it starts the first time and never stops it will just continue to pump but no spin. The 3-5 second pause allows the transmission to shift to spin. If it does not do this the problem is your timer. You may need to do this a few times to verify the problem.

If that is not the problem it is likely that you need a new clutch. You will need a technician to install a new clutch for you

An HF Code is a Water Inlet Problem- No or Insufficient Water Supply.

Press Pause/Cancel twice to cancel the cycle. Then, unplug the washer.

Run down the list again:
Make sure faucets are completely turned on.
Make sure the fill vavles (screens where water enter machine) aren't clogged.
Make sure the hoses aren't kinked, etc.

Plug the machine back in. Try another cycle. If the problem still occurs, You may need to replace your Water Fill Valve. Let me know if you need any further assistance.

Need a model # to get exact part you will need at rinse most washer go straight cold so I would say water inlet valve if humming sound is present

its a error code for not enough water fast enoght or no water. check fill bibs are on and screens inside fill valve are clean if ok . make sure you do not have steel branded flow retrickers fill hoses it if so replace hoses. washer has to get a amount of water fast or it will code out

from what you say it doesnt sound like a water valve. does it fill to correct level the first time round?
