Understanding the Problem
This guide covers the most common problems owners see with the KitchenAid KDTM354ESS3: won't start, won't fill, won't drain, poor cleaning, leaking, and unusual noises. Below are practical diagnostic steps and repair actions you can perform with basic tools and a multimeter. Always disconnect power and water before working on the dishwasher. 1) Quick checks (do these first): a. Confirm the dishwasher has power: try another appliance on the same circuit and check the breaker. Ensure the door fully latches and control lock is off. b. Check the user interface: any error codes displayed? If so, note them and consult KitchenAid code list. c. Inspect the filter and spray arms: remove debris, remove and clean the filter basket and spray arms. 2) If dishwasher won't start or will not respond: 1. Verify power at the junction box/kickplate with a non-contact voltage tester (power off first to open) and then turn on to test. 2. Check door latch/strike: a faulty latch prevents start. Test latch for continuity with a multimeter; replace latch assembly if open when latched. 3. Check control lock / delay start settings and reset: hold START/Resume for 3–5 seconds. 4. If control panel is dead but power is present, the touchpad or main control board may be faulty. Inspect for water damage, burn marks, or swollen capacitors and replace the failed component. 3) If dishwasher won't fill with water or has low water: 1. Confirm water supply valve under sink is open. 2. Check the water inlet valve (solenoid valve) for continuity and visible blockage/scale; replace if no continuity or if the valve leaks or doesn't open. 3. Verify float assembly and float switch move freely and have continuity when lifted; clean or replace if stuck. 4) If dishwasher won't drain or displays a drain error: 1. Check and clean the filter, sump area, and garbage disposal knockout plug (if newly installed disposals). 2. Inspect drain hose for kinks and remove any blockages. 3. Test drain pump: with power disconnected, remove the drain pump and check for obstructions (glass, bones). Use a multimeter to test for motor continuity. If the motor hums but doesn’t spin, or has no continuity, replace the drain pump assembly. 4. Confirm check valve or anti‑backflow flap in pump housing is not jammed. 5) If dishes are not getting clean: 1. Clean spray arms: remove and clear jets. 2. Check circulation (wash) pump/motor for noise or lack of water pressure; test motor for continuity; replace if failed. 3. Ensure proper detergent use, water temperature (120°F recommended), and that lower rack isn’t overloaded or blocking spray. 4. Replace filter assembly if torn or excessively worn. 6) If dishwasher is leaking: 1. Inspect door gasket for cracks, gaps, or debris — clean or replace gasket. 2. Tighten or replace hose clamps and check inlet and drain hose connections. 3. Inspect tub seams, pump seals, and circulation/drain pump gaskets for deterioration; replace leaking pump or gasket. 4. Run a short cycle and watch for the leak location (carefully) to identify the source. 7) If dishwasher is noisy (grinding, rattling, loud hum): 1. Remove debris from sump and impeller area; broken glass and hard food particles often cause noise. 2. Check spray arm bearings and rollers on racks; replace damaged rollers or spray arms. 3. If motor bearings are loud, replace the circulation pump/motor assembly. 8) Diagnostic mode and error codes: run the built‑in service diagnostics (refer to KitchenAid service manual for KDTM354ESS3) to read stored fault codes — these narrow down failed sensors, switches, or modules. Safety note: Always disconnect power at the breaker and turn off the water supply before servicing. Use insulated tools when testing live circuits and follow local electrical codes. If you are not comfortable working with electrical components or cutting off water, hire a licensed technician.
Common Symptoms
No power or won't start, won’t fill, won’t drain, poor cleaning performance, leaking, excessive noise, or error codes on the display.
Common Causes
- Faulty door latch or user interface control preventing cycle start
- Clogged filters, spray arms, or drain hose causing poor cleaning or no drain
- Failed drain pump, circulation pump/motor, or water inlet valve
- Damaged door gasket, loose hose/clamps, or pump seal causing leaks
- Faulty electronic control board or sensors producing intermittent or unexplained behavior

Helpful Repair Tip
To confirm a failed drain or circulation pump: remove the lower access panel, run a drain cycle and listen. If you hear a hum but no water movement and the pump impeller is free of debris, the motor is likely burned out and the pump assembly should be replaced.
Frequently Asked Questions
How do I run a diagnostic mode on the KDTM354ESS3 to get error codes?
KitchenAid dishwashers have a service diagnostics mode that cycles the pump, heater, and reads sensors. For model-specific steps, consult the service manual — typically you press a sequence of keypad buttons (e.g., Heated Dry + Normal or similar) to enter diagnostics. If you don't have the manual, use the control panel to reset (turn power off at breaker 30 seconds, then back ON) and if fault persists record any flashing codes and contact parts/service with those codes.
Can I replace the drain pump myself and how difficult is it?
Yes — replacing the drain pump is a common DIY repair if you're comfortable disconnecting electrical connectors and water lines. Steps: cut power and water, remove lower kickplate, disconnect drain hose and electrical connectors from pump, remove mounting screws/clips, swap in new pump, reconnect hose and wiring, test for leaks and proper draining. Keep towels ready and follow safety steps. If unsure about electrical wiring, hire a pro.
