Quick answer
Standing water in the tub usually means the dishwasher's drain path needs inspection. Turn the dishwasher off, check the accessible filter/sump, drain hose, sink drain, disposer connection, and air gap for blockage or kinks, and never put your hand into a disposer. A small amount of water in the sump can be normal on some models; recurring excess water needs Monogram service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Cancel the cycle and inspect the tub after the pump has stopped; do not reach into standing water or a disposer.
Expected result: Only the sump/filter area contains water, or water covers the tub floor.
Next step: Continue with the accessible filter and drain-path checks for excess water.
Why this matters
Why: Some sump water may be normal on models with an ultra-fine filter; excess tub water confirms a drain concern.
-
Check 2
Remove and clean the accessible fine/ultra-fine filter and clear large food pieces from the sump according to the exact model manual.
Expected result: The filter/sump is coated or blocked, or it is clear.
Next step: Re-seat the filter and test once. Do not use drain cleaner in the dishwasher.
Why this matters
Why: A filter or sump blockage can prevent water from reaching the drain pump; a clear area shifts attention to the hose and household drain.
-
Check 3
Inspect the drain hose under the sink for a kink/blockage and check the sink drain and air-gap cap for visible buildup.
Expected result: A hose, sink drain, or air gap is restricted, or all are clear.
Next step: Clear only the accessible restriction and keep hands out of any disposer. Arrange service if it returns.
Why this matters
Why: GE support identifies these connections as common external drain restrictions; a clear external path makes an internal pump/valve issue more likely.
-
Check 4
If a disposer was recently installed or replaced, confirm its dishwasher drain plug was removed using the disposer installation instructions.
Expected result: The disposer connection is new and the plug may remain, or the connection is established.
Next step: Have the installer correct it if the plug cannot be safely accessed. Do not dismantle the disposer for a test.
Why this matters
Why: A retained disposer drain plug blocks the dishwasher outlet; it is an installation condition, not proof of a failed dishwasher pump.

The hose, sink drain, or air gap is blocked or kinked
Do this next
Clear or repair the accessible plumbing condition; use a plumber for the household drain if needed.

PATH 03Next step
What you see
The entire external path is clear but excess water returns
Do this next
Stop repeated cycles and arrange Monogram service.
Helpful context
Understand the symptom
First distinguish sump water from a full tub
Model design matters: GE support notes that water in the sump/filter area can be normal, while water covering the bottom of the tub is a drain symptom. Record the amount and the point where draining stops.
When checks do not resolve it
Need a professional?
Arrange Monogram service for recurring standing water after accessible checks, a pump/internal hose issue, water near electrical parts, or any repair requiring panels. Use a plumber for a blocked household drain.
Common questions
FAQ
Is any water left in a Monogram dishwasher normal?
Some models can retain water in the sump/filter area. Water covering the tub floor is the stronger sign of a drain problem; compare the symptom with the exact manual.
Can I use drain cleaner in the dishwasher?
No. GE support specifically advises against using drain cleaner in the dishwasher. Clear only accessible food or air-gap restrictions and call service when the problem persists.
