GE dishwasher not draining: why water sits in the bottom and how to fix it
The cycle ended, you opened the GE dishwasher, and there's dirty water sitting in the bottom of the tub. Often the machine seems to run normally otherwise. The water just never leaves. This page covers the checks that solve most of these cases, plus what a technician looks at when they don't.

Standing water means the dishwasher couldn't push wash water out through the drain path, which runs from the sump filter through the drain hose to the disposal or sink drain. By far the most common cause is a clog in the filter, sump, drain hose, or disposal connection rather than a failed part.
Check these first
Safe to do yourself. Unplug the appliance before you start.
- Confirm the cycle actually finished
A cycle that got interrupted leaves water behind, and it looks exactly like a drain failure. Close the door, press Start, then let a full cycle or a cancel/drain cycle run all the way to the end. Clean light on and an empty tub? Nothing is broken.
- Pull and clean the bottom filter
Twist the cylindrical filter counter-clockwise, lift it out, then remove the flat screen underneath. Grease, food, and paper labels pile up down there over the years, and this is the single most common reason a GE dishwasher stops draining. Rinse it all under hot water with a soft brush, then reinstall until it locks.
- Reach into the sump and check the impeller
Filter out, power off at the breaker. Scoop the standing water out with a cup and a towel, then feel around the sump opening for glass chips, seeds, twist ties, or broken plastic. Check that the small impeller blades spin without resistance. Debris wedged in there blocks flow even with a spotless filter.
- Run the garbage disposal
Most GE dishwashers drain into the disposal, so a disposal packed with scraps stops them cold. Run it with cold water for about 20 seconds, then try a drain cycle. If the disposal is new, make sure the installer knocked out the plug in the dishwasher inlet nipple. A plug left in place makes draining impossible.
- Look at the drain hose and air gap
Get under the sink and follow the corrugated hose back from the dishwasher, checking for kinks, crushing from stored bottles, or a pinch behind the cabinet. If there's an air gap cylinder on the countertop, pop the cap off and clear out any sludge. Both problems are common. Both are easy to handle yourself.
- Listen while it tries to drain
Start a drain cycle and put your ear near the lower front of the machine. Humming or buzzing with no water moving usually means a jammed or failed drain pump. Silence points instead to a control or wiring problem. Write down what you hear before you call anyone.
What's different in the Phoenix area
Standpipe and filter clogs are routine here
Older Valley homes with original laundry plumbing often have narrow or partly scaled standpipes. If the machine's own filter and hose are clear, the house drain is the next suspect, and that's a plumbing call rather than an appliance call.
Hard water makes this more likely in the Phoenix area
Phoenix-area tap water runs roughly 12 to 20 grains per gallon, which is among the hardest of any major US metro. Scale builds up on inlet screens, valves, heating elements and dishwasher spray arms years sooner than the manuals assume. If this fault points to a fill or heating part, mineral buildup is the first thing a local technician will look for.
Boards fail earlier in hot laundry rooms and garages
Electronics are rated for room temperature. In a garage or an unconditioned laundry room in July, a control board can see 110°F or more for hours a day. Repair companies here see more board failures than the national averages suggest, especially on machines less than five years old.
Common questions about appliance repair in Phoenix
Is there a way to reset a GE dishwasher that will not drain?
Cut power at the breaker for about a minute, restore it, then start a short cycle. That clears a stuck control state. On most GE models, holding Start for a few seconds also cancels the cycle and kicks off a drain, though no reset helps when something is physically blocking the drain path.
Can I just bail the water out and keep using it?
Bailing gets you a look at the sump, but the machine refills and stalls right back out if the blockage is still sitting there. Standing water turns foul fast and can work its way into the tub seal area.
Does vinegar or a drain cleaner fix this?
No. Chemical drain cleaners aren't safe inside a dishwasher and will damage seals and plastic parts. Cleaning the filter, sump, and hose by hand is what actually clears these blockages.
My GE dishwasher is only a couple of years old. Is it still covered?
Most GE dishwashers come with a limited parts warranty of about one year, and certain models carry longer coverage on specific components. Look at your model's warranty paperwork or the GE support site before you pay for a pump replacement.
Why does it drain sometimes but not always?
Intermittent draining usually points to a partial clog or a check valve that sticks rather than a dead pump. Pull the filter and sump cover again and look hard for something small: a seed, a label, a chip of glass.
