Dacor Dishwasher Error Codes: E24, E15, E01, E09 Explained
Quick answer
Dacor DDW24M dishwasher error codes follow a European-platform E-prefix system. E24 = drain pump blocked or failed — the most common fault. E15 = overflow protection activated, water detected in the base; tilt the unit forward to drain the base tray before restarting. E01 = water supply insufficient, check inlet valve and water pressure. E09 = heating element or NTC temperature sensor fault. Start every code response with a 60-second power reset at the circuit breaker. If the code returns immediately, the underlying component has failed and needs technician repair.
Dacor's DDW24M integrated dishwasher — built on a European platform engineered for custom-panel kitchens in McLean, Great Falls, and Potomac — uses an alphanumeric E-code fault system that mirrors the engineering approach of the platform's parent architecture. When a code appears, the dishwasher has detected a specific subsystem fault and stopped the cycle to prevent water damage or incomplete washing. Unlike a generic appliance that stops with no explanation, the E-code system tells you exactly where to look. Most Dacor dishwasher error codes are safe to investigate yourself before calling for service — with the exception of E15 (which requires a specific physical step to clear) and any code involving the heating circuit on an older unit. This guide covers the error codes Northern Virginia Dacor DDW24M owners encounter most frequently, with accurate homeowner steps and clear guidance on when the component has failed and needs a technician.
E24 — drain pump blocked or failed (most common Dacor dishwasher error)
E24 is the most common Dacor DDW24M error code on Northern Virginia service calls. It means the control board has detected that the drain pump is not moving water out of the tub at the expected rate. This can be caused by a physical blockage or by a failed drain pump motor. Start with the blockage check — it resolves a large share of E24 codes without any parts replacement. Step 1: Cancel the cycle and open the door. Remove the lower dish rack. Step 2: Remove the filter assembly at the bottom of the tub. On Dacor DDW24M models, the cylindrical coarse filter twists counterclockwise to release; the fine mesh filter lifts out separately. Clean both under running water — a toothbrush works on the mesh. Step 3: Check the drain sump area (beneath where the filters sat) for food debris, broken glass, cherry pits, or any object that could obstruct the pump inlet. Remove anything you find. Step 4: Check the drain hose connection at the back of the unit and at the sink connection or garbage disposal. A kinked drain hose or a blocked high-loop can simulate a drain pump failure. Step 5: Reinstall the filters firmly, run a short rinse-only cycle, and observe. If the cycle completes without E24, the blockage was the fault. If E24 returns within the first two minutes of any cycle, the drain pump motor has failed — the pump ran, the control board measured insufficient flow, and the pump needs replacement. Drain pump replacement on Dacor DDW24M is a technician repair; the pump is accessible from the front after pulling the unit, and is a direct swap with an OEM Dacor part ($180–$320 installed).
E15 — overflow protection activated, water in the base tray
E15 on a Dacor DDW24M means the overflow protection float switch in the bottom of the unit detected standing water in the base tray — the space between the outer cabinet and the tub. The dishwasher immediately locks out all cycle operations to prevent further water entry. E15 does not always mean the dishwasher is broken; it means water got into the base, which can happen from a small leak that has since stopped, from condensation during a long idle period, or from an actual active leak. The correct homeowner step for E15: (1) Pull the dishwasher out far enough to access the front-bottom panel, or if the unit is panel-ready and fully integrated, simply tilt the front of the dishwasher forward by approximately 45 degrees for 2–3 minutes to drain the base tray by gravity through the weep hole. This is the official procedure for this class of integrated dishwasher, and it works in most cases. (2) Return the unit to level. (3) Perform a power reset at the breaker (60 seconds). (4) Run a short rinse cycle and observe. If E15 clears and the unit completes cycles without recurrence, it was a one-time water accumulation event. If E15 returns quickly, the unit has an active leak — the source is most commonly the door gasket (especially on panel-ready units where door alignment shifts over time), the circulation pump seal, or the inlet valve connection at the water supply line. An active leak causing recurring E15 needs professional diagnosis before the leak damages cabinetry in a custom-integrated installation.
E01 — water supply insufficient or inlet valve fault
E01 on a Dacor DDW24M means the control board detected that the tub did not fill to the required water level within the expected time window. The dishwasher monitors fill rate during the start of every wash cycle; if the tub does not reach the float-switch level within approximately 10 minutes, E01 triggers and the cycle stops. Common causes in order of frequency: (1) Water supply valve not fully open — the supply valve under the sink or behind the dishwasher cabinet may have been partially closed during a plumbing or cabinet installation project. Confirm it is fully open (counterclockwise to open). (2) Water supply line kink — check the braided steel or PVC supply line from the valve to the inlet valve connection at the back of the dishwasher. A tight bend or kink reduces flow enough to trigger E01 on a dishwasher that previously worked fine. (3) Inlet valve screen clogged — the water inlet valve on the back of the DDW24M has a fine mesh screen where the supply line connects. Mineral deposits and debris from the supply line can partially block this screen over time, reducing flow. Shutting off the water, disconnecting the supply line, and cleaning the screen (or replacing the valve) often resolves a persistent E01 when the supply valve and line are confirmed clear. (4) Inlet valve solenoid failed — the solenoid that opens the valve to let water in has failed electrically. The valve does not open, the tub stays dry, and E01 triggers at the start of every cycle. Inlet valve replacement is a technician repair ($130–$250 installed) and is straightforward on the DDW24M.
E09 — heating element or NTC temperature sensor fault
E09 on a Dacor DDW24M indicates a fault in the water heating circuit — either the heating element (a resistance heater in the base of the tub) or the NTC temperature sensor that measures water temperature and signals the control board when the target wash temperature is reached. E09 is a less common code than E24 or E15 but appears on units with hard water scale buildup (a Northern Virginia water quality issue) that has accumulated on the heating element over years of use. Step 1: Perform a power reset at the breaker (60 seconds). An isolated E09 from a voltage sag or surge sometimes clears and does not return. Step 2: If E09 returns at the start of the wash phase (when the dishwasher begins heating water), check for visible scale deposits inside the tub — heavy white deposits on the element (visible as a U-shaped coil in some DDW24M configurations) or throughout the tub interior indicate the water heating circuit is working in a high-scale environment. Running a descaling cycle with citric acid can extend element life, but it does not repair a cracked element. Step 3: If E09 returns consistently, the NTC sensor (most likely failure) or the heating element (second likely failure) has failed. The NTC sensor is a small thermistor mounted in the tub base and is a quick, inexpensive replacement ($80–$130 installed). A failed heating element requires partial disassembly of the tub base ($160–$300 installed). The control board can technically produce E09 if the board's heating circuit monitoring has failed, but this is uncommon and should only be considered after the sensor and element are ruled out.
How to safely clear a Dacor dishwasher error code
The correct reset procedure for all current Dacor DDW24M dishwashers is: (1) Press the Cancel or End Cycle button on the control panel to cancel any active cycle. (2) Open the door to interrupt the cycle fully (if the unit is locked, wait for the cycle timer to time out — this typically takes 60–90 seconds in fault mode). (3) Close the door. (4) Go to the circuit breaker and turn off the dishwasher breaker. (5) Wait 60 seconds. (6) Restore the breaker. (7) Close the door firmly and start a new short cycle (rinse-only or quick wash) to evaluate. For E15, follow the tilt procedure described above before performing the power reset — a power reset without draining the base tray will immediately re-trigger E15. For E24, clean the filter assembly before resetting. For E01, confirm water supply is open and the supply line is clear before resetting. A code that clears after a power reset and does not return was a transient electrical fault — most commonly from a power fluctuation or a momentary sensor reading outside specification. A code that returns within the first two minutes of the next cycle means the underlying component has failed: the drain pump cannot move water (E24), the overflow float is still wet (E15, base tray not fully drained), the water is not flowing in (E01, valve failed), or the heating circuit is open (E09, sensor or element failed). At that point, continued resets will not resolve the fault — the component needs professional diagnosis and replacement.

Frequently Asked Questions
What does Dacor dishwasher error code E24 mean?
E24 on a Dacor DDW24M means the drain pump is blocked or has failed. Start by removing and cleaning the filter assembly at the bottom of the tub — debris blocking the pump inlet is the most common cause and clears without parts replacement. If E24 returns after cleaning the filter and checking the drain hose, the drain pump motor has failed and needs replacement. Call (571) 571-1664 for same-day diagnosis.
My Dacor dishwasher shows E15 — is it leaking?
E15 means the overflow protection float detected water in the base tray. Tilt the front of the dishwasher forward 45 degrees for 2–3 minutes to drain the base, then perform a 60-second power reset at the breaker. If E15 clears and doesn't return, it was a one-time accumulation. If E15 returns quickly, the unit has an active leak — door gasket and circulation pump seal are the most common sources in panel-ready installations. Call (571) 571-1664.
Do you repair Dacor DDW24M integrated dishwashers?
Yes. We service Dacor DDW24M integrated and panel-ready dishwashers across Northern Virginia and DC. Custom-panel dishwashers need a technician familiar with the panel removal and door alignment process — working on a panel-ready unit without that experience risks misaligning the door and triggering E15 again. We carry common DDW24M parts and provide a written estimate before any work begins. Call (571) 571-1664.
