I have a Whirlpool duet steam that gave me a F21 code. I cleaned out the trap and hoses leading to the drain. The machine will fill w/ water and just when it should kick on the pump to drain, the code comes up again. I'm thinking it may be the pump. Any suggestions before I order a replacement? Thanks in advance.....
ANSWER Hello Paul,
Check the drain housing to make sure that there is nothing clogged inside the pump and make sure that when calling to drain the pump is getting 120 vac. If it is and nothing is clogged then replace the pump assembly.
