Frigidaire Dishwasher Lower Spray Arm 5304507158, Replaces 154821902, 154821903, 154830302, 154830303, 5304496886, 5304496935, 5304496936, 5304498139, 5304506532, 5304506660, 5304507040, 5304507159

The Frigidaire 5304507158 OrbitClean Lower Spray Arm rotates during the wash cycle and distributes pressurized water from the circulation system across dishes in the lower rack. The orbital section increases spray coverage across the rack. It replaces discontinued Frigidaire and Electrolux part numbers 154821902, 154821903, 154830302, 154830303, 5304496886, 5304496935, 5304496936, 5304498139, 5304506532, 5304506660, 5304507040 and 5304507159.

The spray arm distributes water but does not generate wash pressure. Similar cleaning problems can also result from a blocked filter, restricted sump, low water level, damaged spray-arm support or a weak circulation pump. Confirm the drain path and water supply before ordering.

Is This the Right Part?

Confirm the complete model number before ordering. Similar-looking lower spray arms may use different supports, retainers and water-delivery configurations. Match the full model number including all suffixes and revision digits.

Common Symptoms

• Dishes on the lower rack coming out dirty or with food residue after a full cycle
• Uneven wash coverage — some areas of the lower rack clean well, others do not
• Spray arm cracked, split, warped or unable to rotate freely
• Orbital section detached or contacting the heating element during operation
• Unusual rattling or contact noise from the lower rack area during the wash cycle

Check Before Replacing

• Remove the spray arm and flush the jets under running water — mineral deposits and food debris can clog the holes and mimic a broken arm
• Inspect the spray-arm support and retainer for damage or misalignment that prevents free rotation
• Check the dishwasher filter and sump for blockage — a restricted filter reduces water flow to the spray arm
• Verify household water pressure and the water inlet valve — low fill level reduces spray coverage regardless of arm condition

Installation Notes

1. Disconnect electrical power before servicing the dishwasher.
2. Pull out the lower rack and locate the spray arm hub at the base of the tub.
3. Unscrew or unclip the old arm counter-clockwise by hand — no tools required.
4. Compare the new arm with the original before installing; verify the support and retainer interface.
5. Thread or snap the new 5304507158 onto the hub and confirm it spins freely before replacing the rack.
6. Run a test cycle and verify wash coverage before closing up.

Use a qualified technician when diagnosis or installation is outside your experience.
