i get an 'e1' or 'e3' error code on the display after it runs for a few minutes

Diagnosis

The E1 and E3 error codes on the Samsung Bespoke AutoRelease DW80B7070AP indicate a failure in the water management cycle, specifically regarding the timing of filling and draining. An E1 error triggers when the pressure sensor detects that the tub has not reached the required water level within a predetermined timeframe (usually 60 seconds). This is typically caused by a restriction in the water inlet path or a failure in the water inlet valve, preventing the machine from filling fast enough to satisfy the control board's timing window. An E3 error occurs when the dishwasher fails to drain the water completely or detects a blockage during the drain cycle. Because this model features the AutoRelease door, the machine is particularly sensitive to drainage levels; if water remains in the sump, the system will halt the cycle to prevent leakage when the door automatically pops open. You can confirm these issues by checking the bottom of the tub: if E1 occurs, the tub will be dry or barely filled; if E3 occurs, you will likely see standing water around the filter assembly after the cycle aborts.

How to Fix It

Follow these specific steps to resolve the water flow and drainage issues:

1. Clear the Inlet Path (For E1): Turn off the water supply valve under the sink. Disconnect the braided steel inlet hose from the back of the dishwasher. Inspect the small mesh filter screen located inside the dishwasher's water inlet valve port. Use a needle or a small brush to remove sediment or calcium buildup from this screen. Reconnect the hose and ensure the valve is turned fully counter-clockwise to the open position.
2. Inspect for Kinks: Pull the dishwasher out slightly to ensure the inlet hose is not pinched against the cabinetry or kinked, which restricts Gallons Per Minute (GPM) flow.
3. Clean the Filtration System (For E3): Rotate the cylindrical filter assembly counter-clockwise and lift it out of the tub. Remove the coarse filter and the micro-filter. Scrub both with a soft brush and warm soapy water to remove grease and food debris. Reach into the sump area with a flashlight to ensure no hard objects (like broken glass or plastic ties) are obstructing the drain pump impeller.
4. Verify the High Loop: Ensure the corrugated drain hose is looped higher than the dishwasher's outlet before connecting to the garbage disposal or sink drain. If the hose is flat on the floor, gravity will pull dirty water back into the tub, triggering an E3 error. Secure the hose to the underside of the countertop using a zip-tie or mounting bracket.
5. Clear the Disposal Connection: If the dishwasher drains into a garbage disposal, ensure the disposal is clear of debris and that the knockout plug was removed during installation.

If That Didn't Work

• Replace the Water Inlet Valve: If the E1 error persists despite a clear filter, the solenoid in the inlet valve (Part No: DC97-XXXXX) may have failed electrically. Test the valve for continuity using a multimeter; if the coil is open, the valve must be replaced to allow water to enter the machine.
• Inspect the Drain Pump: For E3 errors, the drain pump may be mechanically seized or the motor may have burnt out. Remove the bottom kickplate and inspect the pump for leaks or humming sounds without movement. If the pump doesn't spin when the drain cycle starts, replace the pump assembly.
• Check the Pressure Switch/Sensor: The pressure sensor may be clogged with soap scum or debris, sending a false "empty" or "full" signal to the board. Locate the pressure tube and ensure it is clear of obstructions and that the sensor is clicking properly.
• Hard Reset the Control Board: Power the unit off at the circuit breaker for exactly 10 minutes. This clears the volatile memory of the control board and can sometimes reset a "ghost" E3 error caused by a momentary sensor glitch.

Heads Up

• Use High-Efficiency Detergent: Only use pods or powders specifically labeled for automatic dishwashers. Using standard soap creates excessive suds, which can trick the pressure sensor into triggering an E3 error.
• Monthly Filter Maintenance: To prevent E3 errors, clean the micro-filter every 30 days. Grease buildup on the mesh can slow drainage enough to trigger the timer.
• Check Your Water Pressure: This model requires a minimum of 20 PSI to operate the inlet valve correctly. If you have a low-pressure home system, you may experience intermittent E1 codes.
• Avoid Overloading: Overcrowding the bottom rack can block the spray arms, causing water to pool in areas that trigger sensor errors.
