Dryer stops with E21, often shortly after start; may not pump out condensate water and may trigger leak tray float switch on some models.

Safety first: Disconnect mains power. Be prepared for water spillage when accessing the pump area.

• 1. Access pump area: Remove the lower front panel or rear panel (depending on model) to access the condensate pump housing.
• 2. Drain residual water: Tilt the dryer slightly backward and use towels or a shallow tray to collect any water in the base tray. Some models have a drain plug—open it carefully.
• 3. Inspect pump: Disconnect the pump from its hoses. Check the impeller area for coins, buttons, or heavy lint clumps. Remove all obstructions and rinse the housing.
• 4. Check hoses: Inspect the small hoses to and from the pump for blockages or kinks. Flush them with warm water.
• 5. Electrical check: Ensure the pump connector is firmly seated and free from corrosion or burnt pins. Do not work on live wiring.
• 6. Reassemble and test: Refit the pump and hoses, restore power, and run a short cycle to confirm that water is being pumped correctly.
• 7. When to call a technician: If the pump does not run or hums without turning, the pump motor is likely faulty and should be replaced by a qualified technician.
