Quick Answer: Check the Door Before the Actuator#
Most likely: the dispenser door is simply being blocked or bound shut. Something in the load fouling the door's swing accounts for roughly 30% of "detergent pod still in the cup" complaints across all platforms, and dried gel detergent on the hinge is a close second — both are free to fix. Only after the door is confirmed free does the diagnosis turn to the release mechanism, and here Kenmore is not one machine: the actuator depends on who built it. A Whirlpool 665 uses a bi-metal strip, an LG 630 uses a wax motor, and a Frigidaire 587 uses a solenoid. The symptom looks identical from outside, but the test and the part differ by platform.
Likely Causes at a Glance#
| Cause | Likelihood | What to check |
|---|---|---|
| Load blocking the dispenser door | ~30% | Manually swing the door through its full arc; if any dish, tine, or utensil touches it, rearrange the load |
| Detergent residue binding the door | Common | Clean the cup, hinge, and latch with hot water and a stiff brush, focusing on the hinge pin |
| Bi-metal actuator failed (Whirlpool 665) | Platform-specific | Resistance across the strip terminals should be 10–50 ohms; infinite = burned open |
| Wax motor failed (LG 630) | Platform-specific | It works one cycle and not the next; trigger it in diagnostic mode |
| Solenoid burned open (Frigidaire 587) | Platform-specific | The fastest-acting design; the coil opens from years of activation |
| Control board dispenser relay | Occasional | Actuator tests good but never gets voltage during the cycle |

Walking Through the Diagnosis#
Before opening anything, run the two free checks. Load the dishwasher as you normally would, then open the dispenser door by hand through its full arc — if any dish, rack tine, or utensil contacts it during the swing, that is the problem, so rearrange the load. Next, look at the hinge and latch: gel-type detergent leaves a sticky film that builds up over many cycles and can physically bind the door, so clean the cup, hinge, and latch surface with hot water and a stiff brush, paying special attention to the hinge pin where residue collects.
If the door is mechanically free, identify your platform and test the actuator with the power disconnected. On a Whirlpool 665, remove the inner door-panel screws (Torx T20), find the two-pin dispenser connector, and measure resistance across the bi-metal strip: 10–50 ohms is healthy, while infinite ohms means it burned open and the dispenser assembly needs replacing. The 665 assembly is integrated — cup, door, actuator, and housing come as one unit held by two to four screws inside the door. On an LG 630, the wax motor is a separate cylinder with its own two-wire connector; it will not test reliably with a meter at room temperature, so the honest check is to enter diagnostic mode and trigger the dispenser test — if the motor does not fire, replace it. Wax motors give no warning, working one cycle and dead the next. On a Frigidaire 587 the solenoid is the fastest-acting release but its coil can burn open after years of use. If the actuator itself tests good, the control board may not be sending it power: check for voltage at the connector about 10–15 minutes into the wash (advanced — it means running with the panel open, so leave live 120V checks to a pro), and if none arrives while the board is otherwise working, the board is the fault.
Repair or Replace? The Short Version#
This repair almost never justifies replacing the dishwasher. The most common fixes cost nothing — rearranging the load or cleaning the hinge — and even the actuator is an inexpensive part on any platform, with the LG-platform wax motor often cheaper under the LG part number than the Kenmore cross-reference. The only reason to bring in help is the live-voltage board test or an integrated 665 assembly swap on an older unit; either way, a diagnosis is far cheaper than a new machine — book an EasyBear technician.

Frequently Asked Questions#
Why is the detergent pod still in the cup after the cycle?#
Most often the dispenser door never opened because something in the load blocked its swing, or dried gel detergent glued it shut — both are free to fix. If the door is clear and clean, the release actuator has failed, and which part depends on your platform: a bi-metal strip on a Whirlpool 665, a wax motor on an LG 630, or a solenoid on a Frigidaire 587.
How do I know which dispenser platform my Kenmore uses?#
Your full model number tells you — search it (for example 665.13242K900) on a parts site rather than a generic term, because Kenmore sold dozens of 665-prefix models with different dispenser configurations. In general a 665 prefix is Whirlpool-built (bi-metal), a 630 prefix is LG-built (wax motor), and a 587 prefix is Frigidaire-built (solenoid).
Can I still run the dishwasher while I wait for the part?#
Yes, as a stopgap. Drop a detergent pod in the bottom of the tub instead of the dispenser — it dissolves during the pre-wash, which cleans less effectively but works — or smear liquid detergent on the inner door before closing. These are temporary; the dispenser exists to time release to the main wash, so restore it for proper cleaning.
