Understanding the Problem
If your Whirlpool WM2801HLA washer is not draining, is making grinding or humming noises during the drain cycle, or is leaking from the base, the water (drain) pump is a likely suspect. The pump moves water out of the tub and into the household drain; when it fails or becomes blocked the washer will stop mid-cycle, show error codes, or leave water behind. Failure modes include an electrical fault in the pump motor, a broken or damaged impeller, or a clog from lint, coins, buttons, or debris. Before replacing the pump, confirm that the issue isn’t a clogged drain hose or blocked filter/trap. Many drain problems are caused by foreign objects caught in the pump housing or hose. If clearing blockages doesn’t restore normal draining or if the pump motor hums without turning, replacing the pump assembly is usually the correct repair. Always disconnect power and water before servicing the washer, and verify the correct replacement part for your exact WM2801HLA serial number.
Common Symptoms

Helpful Repair Tip
Listen during the drain cycle — a loud humming or grinding with no water movement indicates a bad pump motor or jammed impeller. To confirm, remove the lower access panel, visually inspect for debris, then disconnect power and test the pump motor for continuity with a multimeter. No continuity or an overheated/hot motor means replace the pump.
Frequently Asked Questions
Can I replace the drain pump on my WM2801HLA myself?
Yes — replacing the drain pump is a common DIY repair if you are comfortable disconnecting the washer from power and water and working under the machine. Typical steps: unplug the washer, shut off and disconnect water, tip or raise the washer per the service manual to access the pump (or remove the lower access panel), drain any remaining water into a shallow pan, remove the hose clamps and electrical connectors, unbolt the pump, swap the new pump in, reattach hoses/clamps and electrical connectors, then test. Expect 30–90 minutes depending on experience. If you’re unsure or uncomfortable, hire a technician.
How much does it cost to replace the water pump?
Parts typically range from about $30–$120 for a replacement pump, depending on OEM vs aftermarket. If you hire a technician, total repair cost including labor is commonly $120–$300 depending on local labor rates and diagnostic fees. Always confirm the correct part number for your exact WM2801HLA model/serial and factor in any additional parts (hoses, clamps, gaskets) that may need replacement.
