Oversudsing & Suds Lock
Oversudsing & Suds Lock
/
If washers time out and shut off without an end of cycle signal
(and without going through the spin cycle), the washer has
experienced suds lock, a possible occurrence with all front
loader washers (regardless of manufacturer).
• Suds lock
: Suds lock comes from suds (airy foam)
interfering with water level sensors (pressure switches).
Electronic controls are fooled into thinking water hasn’t been
removed fully, so washers won’t go into spin cycles. Drain
pumps can also get air locks in them.
• Cause: Suds lock & oversudsing come from using too
much detergent, using the wrong kind of detergent (not HE) or
overloading washers (trapping suds in clothes).
• Solution: Where oversudsing has occurred, have the
washer cleaned out every 6 months by running it without
clothing using a hot water wash (with cold water rinse) & ½
gallon of white vinegar. When suds have overflowed, run a
cold water rinse using 1 gallon of white vinegar. NOTE
: Don’t
use vinegar routinely to avoid possible damage to washer
parts.
• Customer education: Educate customer on type (HE)
and amount of detergent to use. To remove suds from clothes,
have customer rewash clothes with liquid fabric softener, ½
recommended amount of detergent & a cold water rinse.
NOTE: Where possible, handle such calls
over the phone without making service calls.
TIP: Because front loader washers wash the
same amount of clothes more efficiently and
with much less water than top loader washers,
high efficiency (HE) detergent specially
formulated for front loader washers is needed.
Have customers follow detergent directions
and not expect to see suds.
TIP: Powdered detergent works better than
liquid detergents (due to more surfactants in
liquid detergents).
