DRAIN PUMP
(Your model may vary)
Before performing this operation, verify which version WM2277 you are repairing.
Some do not have the recirculation pump.
The drain pump and the circulating pump are attached to either side of the filter
housing. The pumps are different and are not interchangeable. The drain pump is
used to exhaust the water from the washer. The recirculating pump serves three
purposes: it sprays water from the tub onto the laundry, creating a better
saturation of detergent and better rinsing, it keeps the window clean, and it
allows the customer to see water in the tub. The filter between the pumps is not a
lint filter in the traditional since. It serves to trap larger objects (keys, coins,
buttons, etc.) that may find their way into the washer and protects the pumps
from physical damage.
Depending upon which version you have, the washer may not have a circulating
pump (the pump on the right) and the corresponding electrical and plumbing
connections. The pump housings are very similar but not interchangeable, and
the circulating pump cannot be added to models that are not so equipped at the
factory.
This photo shows the drain pump and
pump housing for the models without
the recirculating pump. The housings
look very similar but are not
interchangeable and cannot be
modified to fit models that include the
recirculation pump.
The pump should read 120 VAC±10%.
Ohm check should show 15 ~ 20
Ω
between the brown and black wires.
