• Helps correct leaks at the water line connection point
• Replaces nuts that are cracked, cross-threaded, or deformed
• Common symptoms: water dripping at the connection, difficulty tightening the line, or a poor seal after reassembly

• Shut off the water supply and disconnect power before servicing.
• Slide the nut onto the tubing first, seat the tube fully on the fitting, then hand-tighten and snug with a wrench; do not overtighten.
• Inspect and reuse the existing sleeve/ferrule and tube insert if in good condition; replace if worn.
• Restore water and check for leaks at the connection.

The door balance mount is the side-frame bracket that supports the dishwasher's door counterbalance system. When worn or broken, it can let the door drop, slam, bind, or feel heavy. Replacing it restores smooth, controlled door movement. What it does

• Remove the old seal; clean the mounting surface and note seal orientation
• Press the new seal firmly into place, reassemble, and run a leak check

This replacement capacitor stores and releases energy to give an AC motor the phase shift it needs to start and run smoothly. Installing a fresh capacitor can help when a motor hums, struggles to start, or cycles off. What it does

• Provides the phase shift/starting torque an AC motor needs and stabilizes operation
• Helps reduce repeated start attempts and nuisance thermal trips
• Common symptoms of a weak capacitor: motor hums, won't start, or stops shortly after starting
• Physical signs of failure can include a swollen, leaking, or cracked casing

• 1 capacitor

• Disconnect power to the appliance before servicing
• Safely discharge the capacitor with an appropriate resistor/discharge tool before handling
