Understanding the Problem
If your Whirlpool model WDT970SAHV0 finishes a cycle but leaves water standing in the tub, the dishwasher is failing to drain. This is usually caused by a clogged filter or hose, a failed drain pump motor, a stuck check valve, or an issue with the disposal/sink drain connection or air gap. The dishwasher may also show an error code or run a drain pump for a few seconds without removing water. Diagnosing the problem requires a few simple checks: remove and inspect the filter/sump for food and debris, verify the drain hose and sink connection are clear, listen for the drain pump during a drain step, and test the pump for power and continuity if you’re comfortable with a multimeter. In many cases cleaning the filter and clearing a kinked hose will restore draining; if the pump is seized or electrically dead, replacement is required.
Common Symptoms
Water remaining in tub after cycle, faint humming under the dishwasher during drain, gurgling at the sink, error codes related to draining, bad odors from standing water.
Common Causes
- Clogged filter, food trap or foreign object blocking the pump intake
- Faulty or seized drain pump motor (electrical failure or mechanical jam)
- Blocked or kinked drain hose, faulty check valve, or clogged air gap/disposal connection

Helpful Repair Tip
Run a drain-only cycle and listen at the base of the dishwasher. If you hear the pump hum but no water leaves, the pump or check valve is likely clogged or seized. If you hear nothing, check for voltage at the pump — no voltage points to a control or wiring problem.
Frequently Asked Questions
Can I try to clear the clog myself?
Yes. Start by disconnecting power, removing the lower dish rack, and taking out the filter/screen assembly. Inspect and remove visible debris from the sump. Next, check the drain hose for kinks and disconnect it from the sink/disposal (have a bucket ready). If the hose is clogged, flushing it with water will often clear the obstruction. If the pump intake is blocked or the pump motor is noisy/hums but doesn’t move water, replacement may be necessary.
How much will it cost to fix a dishwasher that won't drain?
If the issue is a clog you can often fix it yourself for little or no cost. A replacement drain pump assembly typically costs $50–$180 for parts; professional labor adds $100–$250 depending on region. If the control board or wiring is the problem, parts and labor will be higher. Always confirm the exact part for WDT970SAHV0 before purchasing.
