Quick answer: A GE or GE Profile dishwasher that won't drain usually comes down to a clogged filter, a clogged drain hose or air gap, or the drain pump. Many GE models show a C1 code when the drain is slow or not happening; others just leave standing water at the end of the cycle.

The known GE issue: On GE and GE Profile, check the filter and the drain hose run before buying a pump: those are the cheapest and most common fixes. If the drain worked until a new garbage disposal went in, the disposal knockout plug is the first suspect.
What's actually different about a GE
Clogged filter or food chopper Easy
Newer GE and Profile models have a removable filter at the bottom that clogs with food. Older models use a hard-food chopper under the lower spray arm that jams on glass, seeds or labels.
What you can check: Pull the bottom rack, twist out the filter and rinse it under the tap. On older models, check around the chopper for debris (power off first).
Drain hose, air gap or disposal Moderate
A kinked or clogged drain hose, a clogged countertop air gap, or a new garbage disposal with its knockout plug still in place stops the water leaving.
What you can check: Clean the air gap cap. If the problem started after a disposal swap, confirm the knockout plug was removed. Check the hose behind the unit isn't kinked.
Drain pump Pro
A hum with standing water, or no drain sound at all, points at the pump.
What you can check: Technician replacement.
GE dishwasher fault codes
C1
Drain slow or not happening: clean the filter, check the hose and air gap, then the pump
Try this first: Press Start/Reset (or Cancel) to drain. If water stays, cut power at the breaker for 1 minute, clean the filter, then run a short cycle.

Water in the bottom of the dishwasher after a cycle is a classic — and usually simple — problem. A lot of the time it's something you can clear in a few minutes, especially if a new garbage disposal was just installed. Here are the causes in the order we check them.
Safety first: Turn the dishwasher off at the breaker before reaching near the drain pump. Scoop out standing water with a cup and towel first.
Clogged filter or sump Easy
Food, grease, and debris build up in the filter at the bottom of the tub and block drainage. This is the most common cause and an easy clean.
What you can check: Remove the bottom rack, twist out the filter, and rinse it under hot water. Clear any debris in the sump.
Garbage disposal knockout plug Moderate
If a new garbage disposal was recently installed and the dishwasher won't drain, the installer likely forgot to knock out the drain plug inside the disposal inlet. Extremely common.
What you can check: Check under the sink — if a new disposal went in recently, the knockout plug may need to be removed from the disposal's dishwasher inlet.
Clogged or kinked drain hose Moderate
The hose from the dishwasher to the disposal or standpipe can clog or kink.
What you can check: Check the hose under the sink for kinks. A deep clog is a technician clear-out.
Drain pump Pro
The pump that pushes water out can fail or jam with glass or debris.
What you can check: A humming pump with no draining points here. Replacement is a technician repair.
Check valve stuck Pro
A one-way valve keeps drained water from flowing back; if it sticks, drainage suffers.
What you can check: Not a typical DIY check. Diagnosed by a technician.
Is it worth repairing?
The vast majority of dishwasher drain problems are cheap fixes — a filter clean, a knockout plug, or a hose. Even a drain pump is an affordable part. A dishwasher that won't drain is almost always worth repairing.
Frequently asked questions
Why is my GE dishwasher won't drain?
A GE or GE Profile dishwasher that won't drain usually comes down to a clogged filter, a clogged drain hose or air gap, or the drain pump. Many GE models show a C1 code when the drain is slow or not happening; others just leave standing water at the end of the cycle.
Is there a known issue with GE dishwashers won't drain?
On GE and GE Profile, check the filter and the drain hose run before buying a pump: those are the cheapest and most common fixes. If the drain worked until a new garbage disposal went in, the disposal knockout plug is the first suspect.
Why is there water at the bottom of my dishwasher?
A small amount is normal; a full pool after a cycle means it didn't drain. The usual causes are a clogged filter, a garbage-disposal knockout plug that was never removed, a kinked drain hose, or a failed drain pump.
I just got a new garbage disposal and my dishwasher won't drain — why?
This is very common. New disposals ship with a knockout plug in the dishwasher inlet that must be removed during installation. If it was missed, the dishwasher can't drain into the disposal. Removing the plug fixes it.
Can I fix a dishwasher that won't drain myself?
Often yes — cleaning the filter and checking the disposal knockout are safe, simple steps. If the drain pump has failed or there's a deep clog, that's a technician repair.
