GE Dishwasher Not Draining? Causes and Fixes
GE, Profile and Cafe dishwashers are among the most common units in DC-area homes, and 'there is water in the bottom' is their most common complaint. A dishwasher that does not drain is rarely a serious failure; in most cases the water is blocked somewhere between the sump and the sink drain, and the blockage is reachable. The order of checks below moves from the easiest to the one that needs a technician.
A little water is normal; a lot is not
After a cycle, a GE dishwasher keeps a small amount of water in the sump to keep the pump seal wet - about a cup, below the filter. Water covering the floor of the tub, or water that rises when the dishwasher sits idle, is a problem. If water rises on its own, the issue is the drain line backing up from the sink or disposal, not the dishwasher.
Clean the filter and sump
Most GE dishwashers made since the mid-2010s have a removable fine filter in the center of the tub floor under the lower spray arm. Twist it out, rinse it, and look into the sump below for the usual culprits: a glass shard, a popcorn kernel, a fruit sticker, a toothpick. Older GE models with a hard-food disposer instead of a filter can jam on the same debris; with the power off, reach in and feel whether the chopper blade turns freely. A sump cleaned of debris fixes a large share of drain calls on its own.
The new-disposal mistake
If the dishwasher stopped draining right after a garbage disposal was installed or replaced, the knockout plug inside the disposal's dishwasher inlet was almost certainly left in place. Disconnect the hose at the disposal and look for a plastic plug in the inlet; knock it out with a screwdriver and retrieve it from inside the disposal. This is the single most common cause of a 'brand new kitchen, dishwasher won't drain' call, and it is not a dishwasher fault at all.
The drain hose, high loop and air gap
The drain hose must rise to the underside of the countertop - the high loop - or pass through an air gap on the sink deck before dropping to the disposal or drain. Without that rise, sink water flows back into the tub. Check that the hose is looped high and not kinked where the dishwasher was pushed back into the cabinet. If your sink has an air gap and water spurts from it during the drain cycle, the hose from the air gap to the disposal is clogged; disconnect and clear it. A hose full of grease and sludge can be cleared with a wet-dry vacuum from the disposal end.
The check valve and the drain pump
GE dishwashers have a small rubber check valve in the drain path that stops water flowing back after the pump stops. When it sticks or is clogged with debris, the pump pushes against a closed door and the tub stays full. Behind it sits the drain pump itself - on most current GE models a separate small pump at the sump. A pump that hums but moves no water has a jammed impeller or a failed motor; a pump that is silent during the drain phase is not being powered. Both are technician repairs because the dishwasher comes out or the sump comes apart, but they are quick once diagnosed.
Control faults and GE error codes
Newer GE, Profile and Cafe models flash codes or lights when the drain fails: a blinking Start light, an error such as 'drain fault' in the display, or a flashing combination of indicator lights on models without a display. The code tells the technician whether the control saw the pump run and water remain, which points at a blockage, or never energized the pump, which points at the control or wiring. Our general guide to dishwasher error codes covers the common ones across brands. If you have cleaned the filter, checked the hose and the disposal plug, and the tub still holds water, book dishwasher repair and leave the water in place - it tells the technician how far the cycle got. Our GE repair page covers the lines we service most.
