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

f-21 is a blocked drain pump.remove the bottom panel,if you have a shop vac get all the water out,you'll see the pump and in the middle there's a piece that you can turn and pull out,first put towels under and around the pump to catch any water that leaks out,turn the part slowly and with your shop vac catch the water with the vac,take your time and open it little by little catching the water with the vac,when you get all the water out twist the middle part out and clean the catch and feel around in the boot and the pump and make sure you have it cleaned out.stick the middle piece back in and start the washer or you can fill it with a gallon of water and put it into a drain cycle and make sure it drains,if it doesn't you cooked the pump and have to replace it,let me know what you find and next time send the model number.
“F21” on display (Drain Problem) Select PAUSE/CANCEL 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?
According to the instruction book - it appears the machine has been stopped mid cycle then re-started. Switch machine off, turn control knob to a solid circle symbol (they are after every set cycle). Switch machine back on and lights will flash and program is reset. You can then select wash cycle as normal.
Code 21 the check engine light will flash 21 times cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the
ignition key ON means to turn it only as far as it takes to get the
radio to come on. It does not mean to turn the engine on.
under dash connect together the 2 green multiplugs. The CEL light (Check Engine Light) will flash. Slow then fast. Count the slow flashes then the fast ones. I.E. code 21 will give 2 slow flashes then 1 fast = 21.
