Digital display shows E8; unit may stop with water remaining in reservoir

Safety First: Disconnect power before working on the drain system.

• Inspect internal drain: Locate the internal drain hose from the reservoir to the external drain. Remove and flush with hot water to clear slime and debris.
• Check external drain: Ensure the floor drain or standpipe is not clogged. Clear any obstructions.
• Verify slope: The drain hose must slope continuously downward with no traps. Re-route if necessary.
• Check drain valve/pump: On models with a drain valve or pump, confirm it actuates during drain. Replace if stuck or inoperative.
• Reset and test: After clearing, run a cleaning cycle and observe that the unit drains completely within the expected time.

When to call a technician: Persistent E8 after clearing drains may indicate a faulty drain sensor or control board.
