How to Replace 154754502 Upper Spray Arm Assembly on Frigidaire Dishwasher — Step-by-Step

Your dishes come out with food stuck to the top rack, even though the bottom rack is spotless. That's your upper spray arm failing — it's either clogged, cracked, or not rotating properly. The 154754502 upper spray arm assembly is one of the most common replacements on Frigidaire, Kenmore, and Ikea dishwashers. Good news? You don't need a service call for this one.

What You Need Before Starting

This is a straightforward mechanical replacement. No wiring, no complex disassembly.

• Towel or small bucket (to catch water)
• Flashlight (to inspect spray arm mount)
• New 154754502 upper spray arm assembly

Repair Time: 10-15 minutes
Difficulty: EASY

Safety First

Turn off the dishwasher and unplug it from the wall outlet, or flip the dedicated breaker. Pull out the bottom rack so you have room to work. There may be residual water in the spray arm assembly — that's normal. Keep a towel handy.

Step 1: Remove the Top Rack

Pull the top rack all the way out until it stops. Lift the front edge slightly while pulling forward — most Frigidaire models have a release mechanism where the rack wheels sit in the track. If it doesn't come free, look for small plastic clips on each side of the track and squeeze them while pulling.

Step 2: Unscrew the Old Upper Spray Arm

Look at the center of the upper spray arm. You'll see a plastic retaining nut holding it to the water supply tube. Turn this nut counterclockwise by hand — it should spin freely. If it's tight, use a towel for grip. Don't force it with pliers or you'll crack the threads. Once loose, pull the spray arm straight down off the supply tube. Water will drip out, so have your towel ready.

Step 3: Inspect the Water Supply Tube

Before installing the new spray arm, shine a flashlight up into the supply tube opening. Look for debris, calcium buildup, or food particles. If you see white crusty deposits, wrap a damp cloth around your finger and wipe the inside of the tube. This prevents future clogs. Check that the tube isn't cracked — if it is, you'll need part 154783001 (the full rack assembly).

Step 4: Install the New 154754502 Spray Arm

Slide the new spray arm assembly onto the water supply tube. The mounting hub should fit snugly over the tube. Thread the retaining nut clockwise until it's hand-tight — you'll feel it bottom out. Don't overtighten. Spin the spray arm by hand to make sure it rotates freely. It should move with minimal resistance and shouldn't wobble side to side.

Step 5: Reinstall the Top Rack and Test

Slide the top rack back into the tracks. Make sure the wheels are seated properly on both sides. Close the dishwasher door and run a rinse cycle with no dishes inside. Watch through the door window (use a flashlight if needed) to confirm the upper spray arm is spinning. You should see water jets shooting out in a circular pattern.

Testing After Installation

Run a full wash cycle with a load of dishes concentrated on the top rack. After the cycle, check the dishes — they should be completely clean with no residue on plates or glasses. If water pressure seems weak, remove the spray arm and check the spray holes for blockage. Use a toothpick to clear any clogged jets. Models like the FGID2466QF8A and FGID2468UD0A have hard water issues, so inspect every 6 months.

Frequently Asked Questions

Will this spray arm fit my Kenmore dishwasher model 58714028200A?

Yes. The 154754502 is compatible with Kenmore models built by Frigidaire, including the 58714028200A. It replaces the older 154478201 and 154698901 spray arms. Check your model number on the inside edge of the door to confirm.

Why does my new spray arm wobble when it spins?

Either the retaining nut isn't tightened enough, or the water supply tube is worn. Hand-tighten the nut until snug. If it still wobbles, the tube threads may be stripped — you'll need the full upper rack assembly. Don't run the dishwasher with a wobbly spray arm or it'll crack the mounting hub.

How often should I replace the upper spray arm?

Only when it's damaged or clogged beyond cleaning. Most spray arms last 5-8 years. Replace immediately if you see cracks, broken spray jets, or if the mounting hub is stripped. Regular maintenance — cleaning the spray holes every 3 months — extends the life significantly, especially in hard water areas.
