When dishwasher is turned on, water fills in tub for about one minute (about a gallon of water), but then all of the water gets sucked out through the drain.  When wash cycle begins, the spinning arm doesn't spin (it just gurgles) and the center "tower" that is supposed to rise up just gurgles too and won't move.  It appears that it doesn't have enough water pressure to make the arm spin and wash the dishes.  I have tried adding more water to the bottom of the tub right before the wash cycle to see if that boosts the water level/pressure enough to make the arm spin, but it just all gets sucked out through the drain, and I just get a lot of gurgling, but no washing!!!  Is this perhaps a problem with the drain pump solenoid?  Getting frustrated....and the dishes are piling up!

Sounds like siphoning.  Check the drain hose and make sure that:

 

1.  There's a riser loop somewhere in the hose before the drain pipe

 

2.  There's not a tight seal at the drain hose-pipe junction (if it's not draining into a disposal)

 

3.  Also, if draining into a pipe, make sure the hose end is not submerged in standing water in the pipe.

Thank you for the reply, Samurai!!!  After some further investigation and plundering, it turns out that the drain valve solenoid is a mess...the plunger is corroded and rusted and was stuck in the "drain" position, so every time the water filled the dishwasher, it would just get sucked out, and there was not enough water to power the spray arm to wash the dishes.  Even more concerning is that there is now water leaking from the pump housing (which was probably causing the corrosion to begin with...a slow drip before...now it's a BIG drip!).  I could replace the entire pump/solenoid/motor mechanism (even though the motor appears to work fine, but it's sold as a unit/kit), but my dishwasher is now over 14 years old, and the pump and motor repair kit is close to $150...should I put the old mare out to pasture and buy a new dishwasher, or should I take on the repair in hopes that she'll last me a few more years??  (This is actually the first problem I've had with this dishwasher, and with the exception of some of the tines rusting on the lower rack, it was washing dishes just fine until now...so what's a penny pincher like me to do?)


Oh...and P.S.  I did check all the drain hose things you told me to check in your post, and everything seems fine there!

I've put many of those in for customers and they are happy that they remain united with their faithful DW rather than having to get a new one that will definitely no be as dutiful as the one they have.

I'd fix it!

I agree.  If the motor is running you could just replace the solenoid assy P/N WD21X10060.  I can't remember if the gate shaft seal (the source of the leak) comes with the kit.  If not seal P/N WD8X181.
