Frigidaire Dishwasher Not Draining: Causes & Fixes
Quick answer
A Frigidaire dishwasher that won't drain almost always has a clogged filter or blocked drain pump. Remove and rinse the filter assembly (under the lower spray arm on most Frigidaire models) — this resolves the majority of draining complaints in under five minutes. If the filter is clear, check the drain hose for a kink or a high-loop problem before assuming a pump failure.
Frigidaire and Electrolux-branded dishwashers are common across Northern Virginia kitchens, especially in mid-range and townhouse-market homes. Standing water at the bottom of a Frigidaire dishwasher after a cycle is nearly always caused by a clogged filter, a blocked drain pump impeller, a kinked or improperly routed drain hose, or a failed drain pump motor. The good news: the filter and drain pump are accessible from inside the tub without any tools on most Frigidaire models, making this one of the more homeowner-serviceable draining repairs.
Step 1 — Clean the Filter Assembly (Most Common Fix)
Most Frigidaire dishwashers built after 2010 use a removable filter assembly under the lower spray arm — a round coarse filter that captures large food particles and a fine mesh filter underneath that catches smaller debris. When the fine mesh filter is coated with grease, food residue, or mineral buildup, water cannot pass through quickly enough to drain by the end of the cycle, leaving standing water. To clean: remove the lower rack, locate the filter assembly in the center of the dishwasher tub floor (look for a round twist-lock component), turn it counterclockwise and lift straight up. Rinse both filter sections under warm running water — use a soft brush for the fine mesh. Stubborn grease responds to a 10-minute soak in warm water with a drop of dish soap. Reinstall and run a short cycle. Frigidaire recommends cleaning the filter monthly for typical household use; many owners never do this, and the filter is responsible for the majority of Frigidaire dishwasher draining complaints.
Step 2 — Inspect the Drain Pump Impeller for Obstructions
If the filter is clean and water still sits in the tub, an obstruction in the drain pump impeller is the next most likely cause. On most Frigidaire models, the drain pump is accessible from inside the tub after removing the filter assembly: shine a flashlight into the drain sump cavity below the filter and look for a plastic impeller (fan-like blades). Food debris, broken glass, a piece of plastic, or a hard item like a small bone or seed commonly lodges in the impeller blades and prevents them from spinning. Reach into the sump with your fingers (glove recommended) and feel for debris — remove anything you find. Turn the impeller manually with your finger; it should spin freely. If it is seized and nothing is visibly blocking it, the pump motor has failed and needs replacement.
Step 3 — Check the Drain Hose Routing
A drain hose that is not routed in a high loop (arching up to the underside of the counter before going down to the drain or garbage disposal) allows water to siphon back into the tub after the pump stops — the dishwasher drains, but then water flows back in. This is often mistaken for a drain pump failure. Open the cabinet under the sink and trace the dishwasher drain hose: it should form a high loop secured to the underside of the countertop before connecting to the sink drain or disposal. If the hose runs straight from the dishwasher to the disposal without the high loop, pull the hose up, secure it with a zip tie or hose clamp, and run a cycle. Also check the hose for kinks (a sharp bend against the cabinet wall) or a blocked garbage disposal connection — if you recently had a new disposal installed, the knock-out plug inside the disposal inlet must be removed for the dishwasher to drain.
Step 4 — Test the Drain Pump Motor
If the filter is clean, the impeller spins freely, and the drain hose is correctly routed, the drain pump motor has likely failed. On most Frigidaire dishwashers the drain pump is mounted below the tub — to access it fully, the dishwasher must be pulled out from under the counter and the lower access panel removed. The drain pump motor can be tested with a multimeter: disconnect the wiring harness and test across the motor terminals. A working Frigidaire drain pump motor reads approximately 5–20 ohms; an open circuit (no reading) means the motor winding has failed. Frigidaire drain pump assemblies run $40–$90 online. On some Frigidaire models the wash pump and drain pump share a single motor assembly (a combination pump) — confirm your specific model configuration before ordering parts.
Step 5 — Door Latch and Cycle Completion
A less obvious cause of water sitting in the tub is a cycle that did not complete — if the dishwasher door was opened mid-cycle and not fully closed and latched, many Frigidaire models pause at that point and never complete the drain portion of the cycle. Check the door latch: it should click firmly into place and the dishwasher should not be able to run with the door open. If the latch feels loose, does not engage fully, or the door springs back open slightly, the latch assembly may be worn and preventing the cycle from completing correctly. Run a drain-only cycle (on most Frigidaire models: press and hold the Cancel/Drain button for three seconds) to manually drain the remaining water and confirm the pump runs before assuming a pump fault.
When to Call a Specialist
Cleaning the filter and drain hose are homeowner-accessible steps. Replacing the drain pump motor involves removing the dishwasher from under the counter and working with the water inlet and electrical connections. If the dishwasher is leaking while running, shows error codes (Frigidaire dishwasher error codes: ER, i10, i20, i30, i50, i60 — all related to fill, drain, or leak circuits), or the wash pump and drain pump share an assembly on your model, a technician handles this faster and with access to the correct part for your specific Frigidaire model number.

Frequently Asked Questions
Why does my Frigidaire dishwasher have standing water after the cycle?
The most common cause is a clogged filter — the round twist-lock filter assembly under the lower spray arm fills with grease and food residue and blocks drainage. Remove it, rinse it clean, reinstall, and run a short cycle. If that does not resolve the issue, check the drain hose for a kink or missing high-loop, then check for a blocked drain pump impeller. A standing water problem that persists after these checks usually indicates a failed drain pump motor.
How do I force my Frigidaire dishwasher to drain?
Press and hold the Cancel or Cancel/Drain button for three seconds — most Frigidaire models will run the drain pump for approximately 90 seconds to remove standing water. This also lets you confirm whether the drain pump is running at all (you should hear the pump motor and see the water level drop). If the drain pump runs and the water level does not drop, there is a blockage in the pump, hose, or filter — start with the filter.
