Help! KitchenAid Dishwasher Cycle Not Completing

A KitchenAid dishwasher that starts but never finishes is usually stuck waiting on a reading it can't get — the soil (turbidity) sensor, a temperature it can't reach, or a door signal that drops mid-cycle. On KDTM and KDTE models the control board watches temperature, water level, soil level, and the door switch throughout every phase, and any one of those going wrong can halt the cycle. This guide ranks the causes.

The likely culprit#

Most likely: a turbidity (soil) sensor malfunction. The sensor in the sump measures how many particles are in the wash water so the ProWash cycle knows when the dishes are clean, and it also carries a thermistor for water temperature. When it drifts or fails, the ProWash logic may never decide the dishes are clean and keeps washing until the board times out and stops. If the sensor checks out, a heating-system fault is next.

Safety first#

Disconnect power at the circuit breaker before any internal inspection or before removing the inner door panel.

Ranked causes at a glance#

Working through each cause#

1. Turbidity sensor malfunction (30% of cases)#

The turbidity sensor sits in the sump near the filter and uses an optical emitter and detector to gauge how dirty the wash water is, and on KitchenAid it also houses the thermistor. When it drifts, the ProWash algorithm can't confirm the water has cleared, so it keeps extending the wash until the board times out and stops. Its thermistor typically reads around 50K ohms near 72F room temperature; a reading far off that points at the sensor.

2. Heating system failure (25% of cases)#

The board expects the water to reach its target — around 155F on a normal cycle — within a set time, and if the heating element has gone open or the thermistor reads incorrectly, the board waits for a temperature it will never reach and eventually halts the cycle. This is especially common on older units. Test the element for continuity and confirm the thermistor's reading against room temperature.

3. Door latch microswitch intermittent (18% of cases)#

The door latch assembly (W10862259) includes a microswitch that tells the board the door is securely closed, and as the plastic latch cam wears over thousands of open-close cycles the switch can develop an intermittent connection. A momentary "door open" signal mid-cycle makes the board pause or stop entirely. Test the switch for continuity as you actuate the latch and watch for dropouts.

4. Drain pump issue (15% of cases)#

The dishwasher drains between wash and rinse phases, and if the drain pump fails to evacuate the water mid-cycle, the board sees the level hasn't dropped and halts. This looks like a not-draining problem but shows up as a cycle that won't complete, because the drain is needed partway through, not just at the end. Check the pump and sump for a clog and confirm the pump runs.

5. Control board failure (12% of cases)#

The control board (W11413276 on KDTM604K models) manages all cycle timing, and a failed relay, corrupted memory, or firmware lockup — often triggered by a power surge — can stop a cycle at an unpredictable point, sometimes with the display freezing. Stored codes like F1E0 (a memory fault) or F2E1 (a stuck key) point here. Try a hard reset first, then replace the board if it keeps mis-timing.

The short version#

• Turbidity sensor — 30%; ProWash never finishes, the sump sensor reads wrong (about 50K ohms at 72F).
• Heating system — 25%; times out waiting to reach around 155F.
• Door latch switch — 18%; an intermittent door signal, latch W10862259.
• Drain pump — 15%; halts mid-drain, the level doesn't drop.
• Control board — 12%; stops at random points, F1E0 or F2E1 on W11413276.

What the repair usually involves#

A won't-complete repair uses where the cycle stops to narrow the cause — a wash that never ends points at the turbidity sensor or heating, a mid-drain stop at the pump, a random stop at the door switch or board — then tests that part with the power off. The turbidity sensor and door latch are common replacements, verified by running a full cycle to completion afterward.

Keeping it from coming back#

Rinse heavy food off dishes so the turbidity sensor and filter stay clear, close the door firmly so the latch switch isn't strained, and protect the dishwasher's circuit from surges that damage the board. Those habits head off the two most common causes without parts.

When to call a professional#

Call a technician if the cycle keeps timing out after checking the filter and door, if the turbidity sensor, heating element, drain pump, or control board needs replacing, or if stored codes like F1E0 or F2E1 keep returning. The cost depends on which part is at fault plus labor, and a tech can confirm before starting.
