Is this a brand new install or have you been using it?
Has anything broken in it?
Remove the lower rack and then remove both peices of the filter. Remove as much water as you can. Becarefull incase there is still glass in there. If you do not have a wet/dry vac a turkey baster and a bowl work well. In the bottom of the sump area (below the filters) remove the #20-torx screw and make sure there is no glass in the impellor of the drain pump. This is the likely area of trouble. If nothing is found here check where the drain hose enters the house drain. If it goes into the disposall or a pipe check this area for blockages. Post me back to let me know what is found.
