“F21” is a Long Drain error.
If the drain time exceeds 8
minutes this error code will be displayed.
In addition, a
“SUDS” error may also be displayed.
This may be an
indication of a drain pump problem and/or clog in the drain line.
will need to check the following:
- First, attempt to unplug the washer for at LEAST 30
minutes to reset the Central Control Unit (CCU). Sometimes
this is all that is required to correct momentary glitches with the
unit. If the error code returns, proceed to step 2.
- Check the drain hose to make sure it is not kinked
- Check the electrical connections to the pump and
ensure the pump is running.
- Remove the drain pump filter and check for foreign
objects and/or debris.
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.
"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
