Hello,
"F21" is a Long Drain error code which is usually an indication that you
may have an obstruction somewhere in the drainage system. Most
commonly, there is something lodged in the drain pump or inlet line
running from the wash tub to the pump. There is a white screw off cap on
the drain pump that you can remove to inspect the pump impeller and
clean.
You may also have to remove the inlet hose that runs from the bottom of
the wash tub to the inlet side of the drain pump. Debris and small
articles of clothing such as socks or under garments can become lodged
in this area as well causing the drain cycle to fail.
NOTE: A
"SUD" error code can often occur in conjunction with the "F21" error
code. This is due to air being detected in the drainage system, which
can occur if the pump is not running, or if you have an obstruction
BEFORE the pump. You need to remove the inlet hose from the pump to
ensure it is also not blocked. Correct your drainage system fault, and
the SUD error (if displayed) should go away.
NOTE: If these
preliminary measures do not correct your problem, you may have to
replace the drain pump. It does not take much to damage the pump
impeller or motor. Since the error code is generated if the drain cycle
exceeds 8 minutes, if the pump is damaged and can't pump at the required
volume, the error code will continue to appear until the pump is
replaced.
Take care.
Hello & Welcome to FixYa
F21 error is displayed when the washer is unable
to drain, press PAUSE/CANCEL button twice to clear the display. After this
please check the drain hose and drain pump filter for any blockages and make
sure it is not clogged with foreign particles. You can also check the drain
pump to verify that its working. Please get back to me if you have any other
questions.
