Wash Heater; Foreign Object Removal - LG WM0742H Series Training Manual

TRAINING MANUAL
DISASSEMBLY and REPAIR, continued
DRAIN PUMP, continued
The drain pump and the circulating pump are attached to either side of the filter housing.
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.

Disconnect the two electrical connections
to the heater leads.
Disconnect the thermistor.

heating element.
Loosen as far as possible but do not
remove the second nut on the ground lug.

When replacing the heater, be sure the
element slides into the retaining clip on the
bottom of the tub.
Remove the front cover.
Remove the heater element, as described

You can then use a wire to fish out any
foreign objects that have come between
the drum and the tub.
