• Start threads by hand to avoid cross-threading; tighten snugly without overtightening
• If the receiving hole is stripped, repair threads or replace the clip/nut before installing

This float palnut is a push-on retainer that secures the dishwasher's water-level float to its stem. Keeping the float anchored helps the overfill protection work properly, supporting correct fill levels and helping prevent leaks from overfilling. What it does:

• Holds the float in position so it can move freely with water level changes
• Helps the float reliably actuate the overfill/float switch
• Replace if cracked, loose, or missing
• Typical symptoms include a loose or wobbly float, the float popping off, erratic filling, overfilling, or leaks near the float area

• One float palnut

• Disconnect power and turn off water supply before servicing
• Remove the lower rack to access the float assembly
• Remove the old retainer; press the new palnut squarely onto the float stem until snug
• The float moves freely up and down before reassembling

• Typical symptoms: weak or no spray, poor cleaning results, grinding or rattling from pump area
• Often fails from broken vanes or debris; inspect filters/chopper while open

• Disconnect power and water before servicing
• Access is typically from inside the tub: remove the lower spray arm, filter screens, and cover to reach the impeller
• Note the order of parts and transfer any reusable hardware; replace worn O-rings/seals as needed
• Do not overtighten plastic parts; verify the impeller spins freely before reassembly and testing
