• Typical symptoms: no/weak spray action, dishes still dirty, loud humming or grinding during wash
• Leaks at the pump housing or shaft area can indicate the assembly has failed

• Disconnect power at the breaker and shut off the water supply before servicing
• Remove the toe panel and slide the dishwasher out to access the underside
• Have a towel or pan ready for residual water; disconnect wiring and hoses, noting their orientation
• Transfer and secure existing clamps/mounting hardware as needed; ensure seals are properly seated and test for leaks after reassembly
