Understanding the Problem
Brief explanation: If your Whirlpool LSR8133 (8133) washer leaves water in the tub, drains slowly, makes a loud grinding noise during drain, or leaks from the bottom, the most common culprit is the drain (water) pump. The pump forces water out of the tub and into your household drain. Failures are usually caused by foreign objects jamming the pump, motor failure, or a clogged drain hose. Step-by-step diagnostics and repair (practical how-to): 1) Safety first: Unplug the washer and turn off the water supply. Always disconnect power before working on electrical appliances. 2) Confirm the symptom: Run a drain/spin or drain only cycle. Note noise, smell, whether the pump tries to run, and whether water moves at all. 3) Check the easy items: Inspect the drain hose and standpipe for kinks, clogs, or high loops that trap water. Remove the hose from the standpipe and run water out into a bucket to rule out house plumbing blockage. 4) Access the pump: - For LSR-series Whirlpool top-load washers, tilt the washer back or remove the lower front access panel to reach the pump area. Refer to your model manual for the exact access method. - Place towels under the washer—expect some water to spill. 5) Visually inspect the pump and hoses: Look for leaks, loose clamps, or obvious foreign objects near the pump inlet/outlet. 6) Manually check for debris: - Disconnect the small drain hose(s) from the pump (have a bucket ready) and check for coins, socks, hair, or other obstructions. - Spin the pump impeller by hand (if accessible). It should turn freely; binding or roughness indicates damage or debris. 7) Electrical test of the pump motor: - With the pump exposed, use a multimeter on the motor terminals to check for continuity. A healthy pump motor usually shows low but finite resistance (a few ohms to maybe tens of ohms depending on motor). An open circuit (infinite ohms) indicates a burned-out motor. - You can also carefully restore power and observe whether the pump receives voltage during a drain cycle (only do this if you are comfortable and using insulated tools). If the pump gets voltage but does not run, the pump is bad. 8) Check controls that can prevent drain: If the pump is fine but machine won’t drain or spin, test the lid switch (or lid lock) and the drain pump relay on the control board. A faulty lid switch can prevent the drain cycle from starting. 9) Replace the pump if faulty: - Order the correct replacement pump for model LSR8133HQ0 (see Parts section). Typical pump replacements come as a snap-in assembly with inlet/outlet ports and motor attached. - Remove power. Drain remaining water from hoses, remove hose clamps, disconnect electrical connectors, and unbolt or unclip the old pump from the washer tub/mount. - Install the new pump: mount it into place, reconnect electrical plugs and hoses, secure clamps, and reassemble access panels. 10) Test the repair: Reconnect power, run a short drain/spin cycle to verify the washer drains, listen for any unusual noises, and check for leaks. Safety note: Always unplug the washer before accessing internal components. Use safety glasses and gloves to protect against sharp metal edges. If you are uncomfortable working with live voltage, call a professional technician.

Helpful Repair Tip
Before buying a new pump, remove the lower hose from the pump and check for debris; many 'pump failures' are just coins, small toys, or textiles jamming the impeller. Also check for continuity across the pump motor with a multimeter—open coil = replace pump.
Frequently Asked Questions
How much does it cost to replace the water pump on a Whirlpool LSR8133?
Parts typically cost between $30–$120 depending on OEM vs aftermarket and source. Labor (if you hire a technician) is usually $100–$200 depending on rates and travel. If you're comfortable doing the repair yourself it usually takes 30–60 minutes.
Can I run the washer with a bad pump or bypass it?
No. The drain pump is necessary to remove wash water. Bypassing it would leave water in the tub and risk damage or flooding. If the pump is noisy but still moves some water, temporary measures like manually draining the tub may get you through one load, but the pump should be replaced promptly.
