Customer Questions and Answers for Cap Seal by Whirlpool

This cap seal creates a tight barrier between a cap and its mating surface in your appliance. Replacing a worn seal restores a secure, leak-resistant fit and helps maintain proper performance over time.

• Forms a tight seal where the cap seats to prevent leaks and seepage
• Helps maintain intended pressure/flow and keeps contaminants out
• Typical failure signs: drips or moisture around the cap area, loose cap fit, or a flattened/cracked seal
• Age, heat, and detergents/chemicals can harden or deform the seal

• Disconnect power and shut off water before servicing
• Remove the cap and note the seal's orientation
• Clean mating surfaces; seat the new seal fully without twisting
• Reinstall the cap and test operation, checking for a leak-free fit
