WM2277 WASHER PAGE 63 of 84 TRAINING MANUAL
MAIN BOARD
The main board must be replaced if defective; it is not repairable. This diagram is
shown to point you to the various connectors that can be removed or used as
test points. Testing at the connectors will allow the servicer to make a more
complete diagnosis and eliminate some of the time required to disassemble and
check various components. For example, the hall sensor can be tested by
removing the connector at the main board and following the procedure on
page 26.
DRAINING THE SUMP
Pull out the little hose and remove the
end cap. Allow the water (16 ~ 32
ounces) to run into a shallow pan.
Do not pull the hose so far out it kinks
or the water will not drain.
Have a towel handy for leaks and
spills.
