Understanding the Problem
What the drain pump does: The drain pump on your Maytag LAT9200BAW moves water out of the tub and into the drain hose during the drain/spin cycle. When it fails or is blocked the washer won’t drain, may display drain-related error codes, hum loudly, leak, or leave water at the bottom of the tub. Step-by-step diagnostic and repair instructions: 1) Safety first: Unplug the washer and turn off the water supplies. If you must work with water present, have towels and a shallow pan ready. 2) Confirm the symptom: Run a drain/spin or drain-only cycle and listen. If you hear a humming or whining noise but no water leaves, or if cycle times out with water remaining, the pump is a prime suspect. If there’s visible leaking from under the machine during drain, inspect pump and hoses. 3) Check the drain hose and standpipe: Ensure the hose isn’t kinked, crushed, or blocked and that the standpipe is not clogged. Remove the hose from the standpipe and run water through it to confirm flow. 4) Inspect for simple obstructions: Many pumps have a small trap or accessible area where coins, lint, or small items collect. Access the pump area (see access steps below) and look for visible debris around the impeller. 5) Access the pump on a top-load Maytag LAT series: Move the washer away from the wall. For most LAT top-load units, remove the back panel (or tilt the washer back and remove the lower back access) to reach the pump at the bottom front of the machine. Place a pan/towels under the pump before disconnecting any hoses. 6) Visual and mechanical check: With power still off and hoses clamped, disconnect the small hose(s) to the pump and inspect. Try to spin the impeller by hand (carefully). If it won’t turn or you feel grinding, it’s failing or jammed. Remove debris if present. 7) Electrical check: Disconnect the pump’s electrical connector. Use a multimeter set to ohms to check for continuity across the pump motor terminals. A completely open circuit (infinite/OL) usually means a burnt motor. If you see continuity, pump motor might still be mechanically seized or intermittently failing. Note: exact resistance varies by pump; the presence of a measurable resistance is the useful check, not a specific ohm value. 8) Replace if necessary: If the pump is jammed and can't be cleared, is noisy, leaks, or has no continuity, replace the drain pump assembly. Basic replacement steps (how to fix): 1) Unplug washer and turn off water. Shift the washer where you can access the back or underside. Place towels and a shallow pan to catch water. 2) Remove the access panel (usually the back lower panel). Support the washer if you tilt it per the service manual recommendations. 3) Locate the drain pump at the bottom. Note routing of hoses and electrical connector; take a phone picture for reassembly. 4) Loosen hose clamps and remove the drain hoses from the pump (expect some water). Remove any retaining screws or brackets holding the pump to the cabinet. 5) Unplug the electrical connector from the pump and remove the old pump. 6) Install the new pump in reverse order: connect electrical connector, attach hoses with clamps, secure pump mounting, and replace access panel. 7) Restore power and water, then run a test drain cycle checking for proper operation and leaks. Safety note: Always disconnect power before working on the washer. If you’re uncomfortable with electrical testing, accessing the pump, or lifting the washer, hire a qualified appliance technician.
Common Symptoms
Washer won’t drain or take too long to drain, water left in tub after cycle, loud humming/grinding during drain, leaks under the washer, and drain-related error codes.
Common Causes
- Pump impeller jammed by debris (coins, buttons, lint, small clothing items)
- Pump motor electrical failure (open winding or burned motor)
- Clogged or kinked drain hose or blocked standpipe
- Faulty lid switch or control that prevents drain cycle (less common than pump failure)
- Leaking hoses or clamps at the pump connections

Helpful Repair Tip
To confirm pump failure quickly: with power off, remove the pump’s electrical connector and try spinning the impeller by hand. If it’s seized or you find debris you can’t clear, replacement is next. Also listen during a drain cycle — humming without water flow strongly indicates a failed or jammed pump.
Frequently Asked Questions
How do I know the drain pump is really bad and not the hose or lid switch?
Start simple: remove and inspect the drain hose for kinks or blockages and check the standpipe. If clear, run a drain cycle and listen — a humming or grinding noise with no water movement usually points to the pump. Access the pump, remove debris if present, and try spinning the impeller by hand. Finally, with power off, disconnect the pump’s electrical connector and check for continuity with a multimeter; an open circuit suggests a failed motor. If the pump spins freely and has continuity, investigate the lid switch and control board next.
Can I replace the drain pump myself, and how long will it take?
Yes — most handy homeowners can replace the drain pump on a Maytag LAT9200BAW. Required tools: screwdriver set, pliers, towel/pan, and optionally a multimeter. Typical time: 30–90 minutes depending on experience and accessibility. Always unplug the washer and shut off water first. If you’re unsure about electrical tests, water handling, or getting the washer safely tilted, consider hiring a technician.
