dishes are still wet and soapy at the end of the cycle, like it didn't rinse or drain properly

Diagnosis

The presence of soapy residue and standing water on the dishes in the Samsung Bespoke DW80B7070AP indicates a failure in the evacuation phase of the wash cycle. Specifically, the unit is suffering from "backflow" or "incomplete drainage," where dirty, sudsy water remains in the sump area. When the machine attempts the final rinse, it is recirculating a mixture of old detergent and food particles instead of drawing in fresh, clean water. This is often caused by a restriction in the fluid path, preventing the drain pump from pushing water out against the gravity of the drain line. To confirm this, open the door immediately after the cycle ends and remove the bottom rack. Look at the sump area (where the filter sits). If you see a pool of cloudy water or a layer of white foam, the drain system is compromised. Additionally, if you notice the "LC" (Leakage Check) error code on the display, the machine has detected water in the base pan, which often triggers an automatic drain sequence that may be failing due to a blockage.

How to Fix It

Follow these precise steps to clear the drainage path and restore rinse performance:

1. Clean the Triple-Filter Assembly: Rotate the cylindrical coarse filter counter-clockwise to unlock it and lift it out. Remove the fine mesh screen and the micro-filter. Use a soft brush and warm soapy water to scrub away the biofilm and grease. Inspect the sump hole for any hard debris (like broken glass or plastic ties) that may be jamming the impeller.
2. Verify the High Loop: Open the cabinet under your sink. Locate the corrugated drain hose. Ensure the hose rises higher than the entry point of the sink drain or garbage disposal (the "high loop"). If the hose sags, gravity allows dirty water from the sink to flow back into the dishwasher, leaving soap residue on your dishes. Use a zip-tie or a mounting bracket to secure the hose to the underside of the countertop.
3. Clear the Garbage Disposal Port: If your dishwasher drains into a disposal, remove the dishwasher hose clamp and pull the hose off the disposal nipple. Use a screwdriver or needle-nose pliers to clear any solidified food debris from the disposal's inlet port.
4. Perform a Forced Drain: Close the door and select the "Cancel" button or the "Drain" option (depending on your specific control panel layout) to run a dedicated 60-second pump cycle. Listen for a sharp, mechanical humming sound; if it sounds like it's grinding, there is still a foreign object in the pump.

If That Didn't Work

• Inspect the Drain Pump Impeller: If the filter is clean but water remains, the drain pump (located at the bottom of the unit) may be obstructed. You will need to access the pump from the bottom of the chassis. Check for a "stuck" impeller—often a small piece of bone or a fruit pit wedges itself between the impeller blade and the housing, preventing the motor from spinning.
• Check for Air Locks: If the unit was recently installed or moved, an air lock may be preventing the pump from priming. Run a "Heavy" cycle with the "Extra Dry" option enabled to force a higher volume of water through the system to push out trapped air pockets.
• Evaluate Detergent Compatibility: If the dishes are specifically "soapy" but the water is draining, you may be using too much detergent or a non-HE (High Efficiency) soap. Excessive suds create "air cavitation" in the pump, meaning the pump spins in foam rather than water, which prevents it from effectively emptying the tub.
• Test the Check Valve: Locate the rubber check valve (non-return valve) where the hose meets the pump. If the rubber has perished or is warped, water will flow back into the tub after the pump stops, leaving a soapy residue on the bottom rack.

Heads Up

• Avoid Liquid Rinse Aids: If you are using pods that already contain a rinse aid, avoid adding extra liquid rinse aid to the dispenser, as this can create an over-sudsing condition that mimics a drainage failure.
• Monthly Filter Maintenance: The Bespoke series has a very fine mesh; if you don't rinse the filter under a faucet every 2-4 weeks, the biofilm buildup will slow the drain rate, leading to the "soapy dish" syndrome.
• Check the Air Gap: If your sink has an air gap (the small chrome cylinder on the counter), ensure it is not clogged with debris. A blocked air gap will cause the dishwasher to struggle to push water out, resulting in incomplete cycles.
