Dacor Dishwasher Error Codes: Complete Troubleshooting Guide

Dacor dishwashers combine Samsung's electronics expertise with luxury-tier construction — stainless steel tubs, whisper-quiet operation, and panel-ready designs that integrate seamlessly into custom cabinetry. When your $2,500–$4,500 Dacor dishwasher displays an error code, it's leveraging sophisticated sensor arrays to pinpoint the problem. This guide covers every code you'll encounter on current Modernist and Heritage dishwasher models.

How Dacor Dishwasher Error Codes Display

Error codes appear on the time display panel or the hidden top-edge display (Modernist fully integrated models). On panel-ready models with no visible display, error codes trigger a specific LED blink pattern on the Clean/Sanitized indicator. Count the blinks between pauses to identify the fault.

Basic reset procedure:

1. Press and hold the Start/Reset button for 3 seconds until the display clears.
2. If the code returns, turn off the circuit breaker for 5 minutes.
3. Restore power and run a Rinse Only cycle to test.

Error Code bE — Door Switch/Latch Error

The bE code indicates the control board cannot confirm that the door is properly latched and sealed.

Common causes:

• Door latch mechanism not engaging fully (misaligned after panel installation)
• Door switch failure (microswitch contacts worn)
• Wiring harness pinched during panel-ready installation
• Control board input circuit failure
• Custom panel too heavy, causing door sag

How to fix:

1. Open and close the door firmly — listen for a distinct click from the latch mechanism. On Dacor panel-ready models, heavy custom panels (some exceeding 30 lbs) can cause the door to sag over time, preventing full latch engagement.
2. Inspect the door latch at the top of the door — it should hook cleanly into the strike on the tub frame. Adjust the strike plate if needed (usually 2mm adjustment screws).
3. Test the door switch with a multimeter: should show continuity when the latch is engaged.
4. Check hinge springs and cables — Dacor uses a balanced door system that can lose tension after 3–5 years.
5. Latch assembly replacement costs $60–$120.

Professional repair cost: $200–$350.

Error Code LE — Leak Error / Water in Base

The LE code is a critical safety code — the leak sensor in the base pan has detected water where it shouldn't be.

Common causes:

• Door gasket failure allowing spray to escape
• Pump seal deterioration
• Cracked sump housing
• Loose hose clamp on drain or recirculation hose
• Spray arm over-rotation causing water escape at door joint

How to fix:

1. Immediately stop the cycle and remove standing water from inside the dishwasher.
2. Pull the unit out from the cabinet (disconnect water supply and drain hose first). Inspect the base pan — any water here confirms the leak.
3. Dry the base pan completely and check the float switch for proper operation (should move freely up and down).
4. Run a short cycle while watching under the unit for the leak source. Common points: pump housing, recirculation motor seal, door gasket corners.
5. Door gasket replacement costs $80–$150. Pump seal kit costs $45–$90.

Professional repair cost: $300–$500. Do not operate with an active leak — water damage to cabinetry can cost thousands.

Error Code HE — Heater Error

The HE code indicates the wash water heater is not functioning — either no current flow or the water isn't reaching target temperature within the allotted time.

Common causes:

• Heating element burned out (open circuit)
• Heater relay on the control board failed
• Temperature sensor giving false "already hot" reading
• Wiring connection failure at heater terminals
• Hard water scale insulating the element (California homes)

How to fix:

1. The Dacor heater element is concealed in the sump assembly — not visible from inside the tub.
2. Access the element from underneath the unit. Disconnect power. Measure resistance across heater terminals: should read 10–15 ohms. Infinite = burned out.
3. Check for hard water scale buildup — in California hard-water areas, mineral deposits can insulate the element, causing it to overheat locally and eventually fail.
4. Test the heater relay on the main board (listen for click when the heater should activate).
5. Heater element assembly costs $120–$200.

Professional repair cost: $350–$550.

Error Code tE — Temperature Sensor Error

The tE code indicates the NTC temperature sensor is reading outside acceptable parameters — either open circuit, shorted, or drifted beyond calibration.

Common causes:

• NTC thermistor failure from thermal cycling stress
• Connector corrosion from the wash environment
• Wiring damage from vibration
• Sensor probe physical damage

How to fix:

1. Locate the NTC sensor on the sump housing. On Dacor models, it's typically a small cylindrical probe inserted into the sump wall.
2. Disconnect and measure resistance: approximately 50k ohms at room temperature (77°F). Should decrease with heat — test by holding the probe in warm water.
3. Check the connector for corrosion or mineral deposits. Clean with contact cleaner and a small brush.
4. If resistance readings are correct but the error persists, the control board's analog-to-digital converter may have failed.
5. NTC sensor replacement costs $35–$70.

Professional repair cost: $200–$350.

Error Code OE — Drain Error

The OE code means the dishwasher cannot drain water within the expected timeframe (typically 3–5 minutes for a complete drain).

Common causes:

• Clogged filter system (food particles, broken glass, labels)
• Kinked drain hose (common after installation or cabinet work)
• Drain pump impeller jammed
• Air gap or disposal knockout not removed (new installation)
• Drain solenoid valve failure

How to fix:

1. Remove and clean the triple-filtration system at the bottom of the tub. Dacor uses a fine-mesh filter that captures particles most dishwashers miss — monthly cleaning is essential.
2. Check the drain hose path from the dishwasher to the disposal/drain. Straighten any kinks. The hose should have a high loop or connect through an air gap.
3. If this is a new installation, verify the garbage disposal knockout plug was removed — a common installation oversight.
4. Listen for the drain pump during the drain cycle — humming without draining means the impeller is blocked. Remove and clear any debris (glass shards, fruit pits).
5. Drain pump assembly costs $80–$150.

Professional repair cost: $200–$400.

Error Code IE — Water Inlet Error

The IE code indicates insufficient water entering the dishwasher — it cannot fill to the required level within the timeout period.

Common causes:

• Water supply valve not fully open
• Inlet valve screen clogged with sediment (especially in older California homes)
• Failed water inlet valve solenoid
• Low household water pressure (below 20 PSI)
• Float switch stuck in raised position

How to fix:

1. Check the water supply valve under the sink — ensure it's fully open. Turn it off and back on to verify operation.
2. Turn off the supply, disconnect the inlet hose, and inspect the screen filter inside the valve. Hard water deposits accumulate quickly in California — use white vinegar to dissolve mineral buildup.
3. Measure water pressure with a gauge — Dacor requires 20–120 PSI.
4. Test the inlet valve electrically: the solenoid should read 500–1500 ohms.
5. Inlet valve replacement costs $60–$120.

Professional repair cost: $200–$350.

Error Code PE — Pump/Motor Error

The PE code indicates the main wash pump motor is not operating correctly — either failing to start, drawing excessive current, or running at incorrect speed.

Common causes:

• Wash motor capacitor failure
• Motor winding short or open circuit
• Pump impeller jammed (glass shard, bone fragment)
• Control board TRIAC/relay failure for pump circuit
• Motor thermal overload triggered

How to fix:

1. Listen during a cycle start — does the motor hum without spinning, or is it completely silent?
2. Humming without spinning: likely a jammed impeller. Access the sump assembly from underneath and check for obstructions.
3. Complete silence: check the motor capacitor (if equipped) and wiring connections.
4. If the motor ran previously but now trips the thermal overload, let it cool for 2 hours and retry. Repeated thermal trips indicate bearing failure.
5. Main wash pump motor costs $150–$300.

Professional repair cost: $350–$600.

Error Code AE — Overflow/Leak Sensor Error

The AE code indicates the unit has detected water level above maximum safe threshold, or the overflow protection has activated.

Common causes:

• Water inlet valve stuck open (filling continuously)
• Float switch malfunction (not signaling full)
• Drain issue causing water accumulation
• Excessive suds from wrong detergent
• Sensor circuit failure

How to fix:

1. Cancel the cycle immediately. Check if water is visibly above the door threshold.
2. If the dishwasher appears to be overfilling during a cycle, the inlet valve is likely stuck open. Turn off the water supply immediately.
3. Test the float switch — it should move freely and trigger when pushed up. A stuck float means the board never gets the "full" signal.
4. Verify you're using dishwasher-specific detergent (not hand dish soap — even a small amount of hand soap creates massive suds that trigger overflow sensors).
5. Inlet valve assembly costs $60–$120.

Professional repair cost: $200–$400.

Error Code FE — Water Supply Error

The FE code is similar to IE but specifically indicates water flow rate is below minimum threshold — water is entering but too slowly.

Common causes:

• Partially blocked inlet screen
• Partially closed supply valve
• Failing inlet valve solenoid (weak opening)
• Low municipal water pressure during peak hours
• Long supply line run with undersized tubing

How to fix:

1. Run a kitchen faucet to verify household water pressure is normal. If the faucet is also slow, the issue is house-wide.
2. Check the inlet screen for partial blockage — even 50% obstruction can drop flow below the minimum threshold.
3. Verify the supply line is 3/8" minimum diameter. Some installations use 1/4" tubing that restricts flow.
4. If pressure is adequate and lines are clear, the inlet valve solenoid is weakening — it opens partially but not fully. Replace the valve.

Professional repair cost: $200–$350.

Frequently Asked Questions

Q: Why does my Dacor dishwasher smell even after cleaning? A: Dacor's sealed panel-ready design creates a tighter enclosure than freestanding units. Run a monthly maintenance cycle with dishwasher cleaner (not vinegar — it can damage the rubber seals over time). The fine-mesh filter must be cleaned weekly in heavy-use households. Check the drain hose high loop — improper installation allows sewer gas backflow.

Q: Can I use any detergent in my Dacor dishwasher? A: Use only automatic dishwasher detergent — never hand dish soap. Dacor recommends pods or tablets over liquid for their precision-dosing. Avoid "eco" detergents with excessive plant-based surfactants that cause suds issues. Rinse aid is essential for the Dacor drying system — the AutoRelease door mechanism works best with proper rinse aid levels.

Q: My Dacor dishwasher won't start — no error code shown. What's wrong? A: Check: (1) door is fully latched (listen for click), (2) child lock isn't engaged (hold Child Lock button 3 seconds), (3) delay start isn't active (check display), (4) water supply is on. If none of these, the control board may not be receiving power — check the house breaker and the junction box connection behind the unit.

Q: How often should Dacor dishwashers be professionally serviced? A: Dacor recommends annual professional maintenance for luxury dishwashers — including spray arm cleaning, seal inspection, and pump seal condition check. In hard-water areas like Sacramento and the Bay Area, scale buildup accelerates wear on heaters and valves. Professional descaling every 6 months can extend unit lifespan by 3–5 years.

Q: What is Dacor dishwasher warranty coverage? A: Dacor provides a 2-year full parts and labor warranty — double the industry standard. The stainless steel tub and door liner carry a lifetime limited warranty against rust-through. Register your unit within 30 days at dacor.com to activate coverage. Extended plans are available through Dacor's Distinctive Service program.
