Dissolves limescale, mineral deposits, and odor-causing residues from dishwasher tub and spray system. Use monthly to maintain peak cleaning performance.

Fixes dishwasher overfilling or not filling properly. This float rises with water to signal when the tub is full. DIY-friendly repair in under 30 minutes.

This water level switch senses the dishwasher's tub float and controls the water inlet. Replacing a worn switch restores correct filling, helping prevent overfilling or dry cycles that can reduce cleaning performance. What it does:

• Monitors the float position to open/close the fill circuit at the proper water level
• Common symptoms: dishwasher won't fill or stops filling too soon
• May also cause continuous filling/overfill if contacts are stuck closed
• Intermittent operation can leave the tub underfilled and washing performance poor

What's included:

• 1 water level (float) switch

Install notes:

• Disconnect power and shut off the water supply before servicing
• Remove the toe/kick panel to access the switch near the float assembly under the tub
• Note wire positions; transfer connectors one at a time and secure the switch in its bracket
• The float moves freely and actuates the switch before reassembly and testing

Screw: 8-16 x 3/8 inch.

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
