Drain line continuously drips or runs to waste even when not regenerating

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn or cut drain seal, Debris on drain seat, Warped piston, Misaligned cam

Safety: Turn off water and power, and relieve pressure before opening the valve head.

Confirm flow: Observe the drain hose. A small occasional drip may be normal, but a steady stream indicates a fault.
Inspect drain port: Disassemble the valve head to access the drain port and piston. Clean any debris from the seat.
Replace seals: Install a new seal and spacer kit, paying attention to correct order and orientation.
Check piston: Replace the piston if it is scored, warped, or cracked.
