Question about Washing Machines
Sir, I had a repairman come out and the pump is working fine....he said to replace the microcomputer and the pressure switch...does this make sense? Again the pump works fine and I don't know why I get a F21 fault.
Sir, I tried these steps...the water drains out of my washer when I fill it up with a garden hose. Also, I back filled the drain line and it was clean and drained? Now what? I have a F21 code/add a garment on my front loading whirhpool washing machine model wfw8300sw00 ser# hlt1682794. I checked the cold & hot water hoses...they were good and no kinks. I checked the drain line...I filled the washer and the water drained out. I back filled the drain line and it was clear. I reset the outside breaker and unplugged the washer overnight....nothing seems to work. I tried different cycles and settings...the same thing code comes up F21/add a garment. thanks in advance
Original Problem Dear Madam/Sir, Thank you for your recent inquiry (#1493340), sent on 3/22/08 at 9:57 pm, regarding your 2006 Whirlpool Washing Machine, model: wfw8300sw00. F21 LONG DRAIN If the drain time exceeds 8 minutes the water valves turn off. NOTES: ¦ After 4 minutes the “Sd” error will be displayed, then 4 minutes later the “F/21” error code will be displayed. ¦ Press PAUSE/CANCEL two times to clear the display. Possible Causes/Procedure 1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 6. If the above does not correct the problem, go to step 7. 7. Unplug washer or disconnect power. 8. Replace the pump.
what I have found is that the washer thinks it is not pumping out .. if your drain pump is clearly removing the all the water in a good time... then the problem is your pressure switch...it is telling the computer that it still has water in the machine...
replace the pressure switch and it will solve your f21 error.
It is a round unit on the right hand side on top...with a tube and wires going to it...let me know if it helps
