Dishwasher not draining: reviewed troubleshooting by brand
Brand-specific dishwasher drain troubleshooting for standing water, drain codes, filters, hoses, and disposer connections.
Standing water after a dishwasher cycle can come from a blocked filter, restricted drain hose, disposer installation issue, household drain problem, or an internal pump/control fault. Some brands also show specific drain codes. The reviewed paths keep leak-protection and electrical safety systems intact.
Before you choose a brand path
Let hot water cool before reaching into the tub, use care around broken glass, and note any exact error code before canceling or resetting the cycle.
Reviewed error codes in this topic: 0C, 5C, 5E, C3, E-24, E24, F56, FTD, OC, OE, SC, SE, i20.
The goal at this stage is to improve the observation, not to guess a failed component. A symptom can have several causes that look identical from the outside. The linked guides below use the manufacturer’s own troubleshooting material to decide which safe external question comes next for each supported brand.
How the reviewed paths differ by brand
Manufacturers often emphasize different first checks because product designs, controls, installation requirements, and error-code conventions vary. The first reviewed step or decision point in the currently reviewed paths includes:
- Amana: Inspect the accessible filter and sump
- Bosch: Was a garbage disposal recently installed?
- Electrolux: Inspect the drain hose
- Frigidaire: Check the drain hose
- GE Appliances: Check the filter and sump area
- Haier: Distinguish normal residual water from a full tub
- KitchenAid: Check the accessible filter and sump area
- LG, Samsung, Whirlpool: Check the filter and drain area
- Maytag: Inspect the accessible filter and sump area
Those differences are why Appliance Verdict does not publish a single generic “replace this part” answer for every appliance with the same symptom. Choose the brand-specific path and, when possible, enter the full model number so recall screening can run and Appliance Verdict can distinguish exact-registry matches from model entries that still need independent verification.

Safety boundary
Dishwashers combine water, electricity, heaters, pumps, and hidden plumbing connections. Stop for active leaking near electrical components, shock, smoke, or any check that requires energized internal testing or bypassing leak protection.
Stop using the appliance for smoke, sparking, electrical shock, active uncontrolled leaking, a gas odor, or any other urgent safety condition. The exact owner and installation documentation for your model takes priority over a general symptom page. Appliance Verdict intentionally stops when the reviewed evidence no longer supports a safe homeowner check.
Source basis for this comparison
The brand paths above are not synthesized from forum votes or part-sales popularity. They are generated from the same structured diagnostic families used by the interactive engine, with manufacturer support as the preferred evidence layer. Source records are reviewed and dated, while part compatibility is kept separate from diagnosis.
