Drain line continuously trickles water even when not regenerating

Safety first: Unplug the unit and place it in bypass. Do not cap the drain line; it must remain open.

Steps to check:

• 1. Confirm continuous flow: Observe the drain line for several minutes to verify a constant trickle when the unit is in service mode.
• 2. Inspect valve seals: Remove the control valve cover and rotor/disc. Inspect the drain port seal and surrounding surfaces for debris or damage.
• 3. Clean and lubricate: Clean the sealing surfaces and apply a thin layer of silicone grease approved for potable water if specified by Whirlpool.
• 4. Replace damaged seals: If the drain seal is cut or worn, replace it. If the valve body is cracked, replace the entire valve assembly.

When to call a technician: Internal valve repairs can be complex; if unsure, contact a professional.
