Understanding the Problem
Brief overview: The KitchenAid KDTM354ESS3 is a top-control, built-in dishwasher. Typical service calls for this model include: it won't start, won't fill or drain, leaves dishes dirty, is noisy, or leaks. Most faults are caused by a handful of components (door latch/lock, water inlet valve, drain pump, circulation pump/motor, heating element/thermostat, float switch or control board). Below are practical diagnostic steps and repair instructions you can follow. Always disconnect power and water before opening the appliance. 1) Safety & tools - Turn off power at the breaker and shut off the water to the dishwasher. - Tools: Phillips and flat screwdrivers, nut driver (1/4" or 5/16"), multimeter, needle-nose pliers, bucket/rags, work gloves. 2) Identify the symptom first (short list) - Won't start or respond, starts then stops, won't fill, won't drain, won't heat, noisy motor, leaks, poor cleaning. 3) General initial checks (quick, do these first) - Check power: confirm breaker on and that outlet (if used) has 120V with multimeter. - Control lock/child lock: make sure control panel isn't locked — consult the user panel for lock icon. - Error codes / blinking lights: note any blinking patterns and consult the manual or service sheet. - Inspect for obvious water leaks under/around unit. 4) If dishwasher won't start / control unresponsive - Check door latch/door switch: the unit will not start if the door latch or microswitch is faulty. With power off, open door and inspect latch for broken plastic or missing striker. Remove inner door panel to access latch if needed. Test latch switch for continuity with a multimeter; it should show continuity when latched. - Check the control lock and touchpad: if touchpad doesn't respond, remove the control panel trim and look for water damage or burnt connectors. You can test the touchpad by inspecting for corrosion and by checking for continuity on membrane switches if you have the service manual connector diagram. - Check voltage to the control board: with power on and door closed to start a cycle, carefully measure incoming 120V at the board’s power connector. 5) If dishwasher won't fill with water - Verify water supply to valve: make sure house water is on and the inlet hose isn't kinked. - Inspect and test the water inlet valve (solenoid): remove toe-kick and turn unit on to a fill cycle. With power on, measure for 120V at the solenoid during the fill stage. If voltage present but valve doesn't open, inlet valve is bad. If no voltage, problem is control/board or float switch. - Float switch: open lower access and locate the float assembly. Ensure float moves freely and test float switch continuity; stuck float or open switch will prevent filling. 6) If dishwasher won't drain - Check for clogs: remove the lower spray arm and sump filter; inspect for food, broken glass, or foreign objects blocking the drain or pump impeller. - Clean the filter and pump area: many drain problems are resolved by removing debris at the sump. - Test drain pump: start a drain or drain/boost cycle. Listen for pump motor noise. With power on and in drain stage, measure 120V at the pump. If voltage is present and pump not running, replace pump. If no voltage, suspect control board or relay. 7) If dishes are not getting clean / poor wash performance - Check spray arms for blockages and ensure they spin freely. Remove and clean jets. - Verify correct detergent and dosing, and that water is hot at the tap (120°F recommended). - Check circulation pump/motor: if you hear the motor humming or no water movement during wash, the circulation motor or impeller may be damaged or jammed. Inspect the sump area and test motor continuity; replace if failed. 8) If dishwasher not heating or drying properly - Many KitchenAid models use a heating element or an integrated heater assembly and a temperature sensor. With power off, access the element and check for continuity with a multimeter. - If the element has continuity but water doesn't heat, suspect the control or temperature sensor. If element open, replace the element. - Note: some models use an in-line wash thermostat or thermistor—test per service manual values. 9) If loud grinding, squealing, or rattling noises - Remove dishes and run empty to isolate noise. Check for foreign objects in the sump or drain pump. - If noise is from the motor area, the circulation pump bearings may be failing; replace the pump/motor assembly. 10) Replacing common parts (general steps) - Always disconnect power & water. Remove lower access panel / toe-kick for access. - For inlet valve: turn off water, disconnect hose, remove mounting screws, disconnect wiring, install new valve, reverse steps. - For drain pump: remove lower access panel, disconnect wiring and hose(s), remove retaining screws/clips, replace and reattach hoses and wiring. - For door latch: open door inner panel screws, disconnect latch harness, swap latch and secure. - For control board: remove inner door panel and top cover per service instructions, document connector locations with photos, unplug connectors, remove board mounting screws, transfer any brackets and install new board. 11) Final checks after repair - Restore water and power. Run a short cycle and check for leaks, noises, proper fill/drain and wash. - Confirm error codes are cleared and unit completes a wash cycle. Safety note: Always disconnect power at the breaker and shut off water supply before servicing. If you’re not comfortable working with live voltage or removing the door panel, call a qualified appliance technician.

Helpful Repair Tip
To confirm a faulty part quickly: reproduce the symptom, then measure for 120V at the component during the cycle stage when it should operate (fill = inlet valve, drain = drain pump, wash = circulation motor). If voltage is present and the part doesn’t work, replace the part; if no voltage, suspect control board or wiring.
Frequently Asked Questions
How do I find the exact replacement part number for my KDTM354ESS3?
