How to Fix F8 E0 (Whirlpool/Maytag Dishwasher)
Quick Answer
The F8 E0 error code on a Whirlpool or Maytag dishwasher indicates a 'Long Drain Time' issue, meaning the dishwasher is taking too long to drain water. The fastest fix often involves clearing blockages in the drain filter or air gap, or ensuring the drain hose is correctly installed.
What Causes This Error
- Clogged drain filter or sump area.
- Kinked, obstructed, or improperly installed drain hose.
- Malfunctioning or clogged air gap (if present).
- Issues with the drain pump, such as blockages or failure.
- Problems with the household drain line.
- Excessive suds or detergent use.
Step-by-Step Fixes
1Clear the Dishwasher Drain Filter and Sump
- Disconnect power to the dishwasher by unplugging it or turning off the circuit breaker.
- Open the dishwasher door and locate the filter assembly at the bottom of the tub. This usually consists of a coarse filter and a fine filter.
- Remove the coarse filter by rotating it counter-clockwise and lifting it out. Then, remove the fine filter (mesh screen) by lifting it.
- Rinse both filter components under running water to remove any food particles, debris, or grease. Use a soft brush if necessary to clean the mesh.
- Inspect the sump area beneath where the filters sit for any remaining debris. Remove any visible obstructions. Reinstall the filters, ensuring they are securely locked into place. Restore power and test the dishwasher.
2Inspect and Clear the Drain Hose for F8 E0 Error
- Disconnect power to the dishwasher.
- Locate the drain hose, which typically connects from the dishwasher to the sink drain or garbage disposal.
- Carefully pull the dishwasher out from its cabinet enclosure to access the rear. Inspect the entire length of the drain hose for kinks, bends, or crushing.
- If the hose is kinked, straighten it. If it appears crushed or damaged, consider replacing it. Disconnect the hose from both the dishwasher and the household drain connection, then check for internal blockages by blowing through it or using a thin, flexible brush. Reconnect securely, ensuring a high loop is present, and test.
3Check and Clean the Air Gap (If Applicable)
- Disconnect power to the dishwasher.
- Locate the air gap, which is typically a small cylindrical fitting on the sink or countertop near the faucet. It usually has a cap that can be removed.
- Remove the air gap cover and then the inner cap. Inspect for any food debris, grease, or mineral deposits that might be causing a blockage.
- Clean any obstructions found using a small brush or a toothpick. Reassemble the air gap, ensuring all components are properly seated. Restore power and test the dishwasher.
4Verify Proper Drain Hose Installation
- Disconnect power to the dishwasher.
- Ensure the drain hose has a 'high loop' or is connected to an air gap. This prevents drain water from flowing back into the dishwasher.
- If connecting to a garbage disposal, ensure the knock-out plug inside the disposal's dishwasher inlet has been removed. If it hasn't, remove it and clear any debris.
- Confirm the drain hose is not inserted too far into the standpipe or sink drain, which can create a siphon effect and prevent proper draining. The hose should extend no more than 6 inches into the drain pipe. Restore power and test.
Advanced Fixes
Inspect and Test the Drain Pump
- Disconnect power to the dishwasher.
- Access the drain pump, typically located at the bottom front of the dishwasher. This may require removing the lower access panel.
- Carefully disconnect the wiring harness and hoses from the drain pump. Inspect the pump impeller for any foreign objects (e.g., glass shards, food debris, small utensils) that might be jamming it.
- If no physical blockage is found, use a multimeter to check the continuity or resistance of the pump motor windings. Consult the dishwasher's service manual for specific resistance values. If the pump shows no continuity or incorrect resistance, it may require replacement. Reassemble and test.
Clear Household Drain Line Obstructions
- Disconnect power to the dishwasher.
- Disconnect the dishwasher's drain hose from the household drain connection (e.g., sink drain or garbage disposal).
- Run water in the sink to which the dishwasher drains. If the sink drains slowly or backs up, the issue might be with the household plumbing.
- Attempt to clear the household drain using a plunger or a chemical drain cleaner suitable for your plumbing system. If the blockage persists, professional plumbing assistance may be required. Reconnect the dishwasher drain hose and test.
