Hi All - My Whirlpool GU1500 dishwasher is leaving food particles. I
watched the repairman clean out the area under the screen under the
lower arm and it worked well for about a month. Now it is back to its
old habits. I cleaned under the screen and no change.
I must say in the future I would avoid this manufacturer - they provide
nothing in they way of useful telephone support, the owners manual is
useless for this kind of routine maintenance and they will only sell
you a repair manual for $$$.
