Understanding the Problem
If your Whirlpool WDT9705AHV0 finishes its cycle but leaves water sitting in the tub, the unit is experiencing a drain failure. This can stem from a simple blockage (food, broken glass, or grease) or from a failed drain pump, clogged hose, or a stuck check valve. The dishwasher’s drain system includes the filter/trap, sump, pump, check valve, drain hose, and discharge connection to the disposal or sink — any of these can stop water flow. Diagnosing draining problems starts with simple, visible checks (filter and trap, garbage disposal connection, and drain hose routing) and progresses to component tests (listen for the pump during drain, check for continuity on the pump motor, inspect the check valve). In many cases the fix is cleaning the filter and hose; when the pump motor is noisy, not running, or shows no electrical continuity, replacing the drain pump assembly is the usual repair.
Common Symptoms
Water pooled in bottom of dishwasher after cycle, gurgling or recurring pump attempts, dishwasher displays drain-related error (or just stops with water present), loud grinding or humming from the pump area.
Common Causes
- Clogged filter/trap or sump with food debris or glass
- Blocked or kinked drain hose or clogged inlet at the disposal
- Failed or seized drain pump motor
- Stuck or broken check valve preventing water flow
- Faulty control board or drain relay (rare) or float switch issue

Helpful Repair Tip
Run a Drain Only cycle and listen at the kickplate area: a working pump should make a steady hum/whir while removing water. If nothing is heard and water remains, test pump continuity or remove and bench-test the pump.
Frequently Asked Questions
How can I tell if the drain pump is bad or just clogged?
First remove and inspect the filter/sump for debris and check the drain hose and garbage disposal connection for blockages. Run a Drain Only cycle and listen: a functioning pump will make a steady hum or whir. If you hear the motor trying to run but no water moves, the impeller may be damaged or the check valve stuck. If you hear nothing, shut power off and test the pump motor for continuity with a multimeter; open-circuit indicates a failed pump. You can also remove the pump and bench-test it with caution (12–120V depending on model) or replace it if mechanical damage is visible.
Can I replace the drain pump myself on a WDT9705AHV0?
Yes, many DIYers can replace the drain pump. Basic steps: disconnect power and water, remove the kickplate or lower access panel, take out the lower spray arm and filter assembly to access the sump, disconnect the electrical connector and clamp(s) on the drain hose, and unbolt or unclip the pump from the sump. Install the new pump with the same orientation and secure all clamps and connections. Important safety notes: always unplug the dishwasher or switch off the breaker before working, have a towel/bin for residual water, and confirm the correct replacement part for WDT9705AHV0. If you’re uncomfortable with electrical testing or getting under the appliance, hire a qualified appliance technician.
