What would stop the washer in our LSE7806A from working?
Let's figure out what it's doing or not doing. From that, we can figure out how to make it do what it's SUPPOSED to do, or stop doing what it's NOT supposed to do.
First... since it was stored, we can pretty safely assume that it was deemed to be suitable for storage - actually functional - when it was put there. Why else would one store it?
So... tell us a little about what happens or doesn't happen. When you plug it in, connect the water, turn on the water, fill the machine with clothing, select a wash cycle, and turn it on... what happens? If NOTHING happens (the machine sits there dumb & silent), check the power outlet to be sure there's good power there. Plug a lamp into the outlet to prove it.
If it hums and clicks but doesn't release any water to fill the tub, doublecheck your water supply. Prove that water does indeed come out of the taps. Also check the little screens in the water connections to the washer - are they clogged full of dirt and sand? Wasp mud nests (from storage)? If all looks well, look closely at the water control solenoids inside the washer. Check power there, verify solenoid operation.
Next... if it fills but doesn't move, doesn't agitate, doesn't spin... check the motor. Verify power there, inspect the drive belt.
If all is well up to this point but it doesn't drain, inspect the belt again and look closely at the pump.
If it makes odd noises, look inside the back or bottom (or remove the top) and determine where those odd noises are coming from. You can track them down by ear (ears are marvelous directional finders for sounds) and hands and eyes.
If you find the absence of power anywhere except in the power cord, look to the washer's control head. Trace power through it (for this a multimeter or AC test light is a handy tool).
Keep us posted on what you're starting with and what you find.
