Frigidaire Dishwasher Scraping Noise: Check Spray-Arm Clearance Before Service

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Cancel the cycle and leave the dishwasher off if the scrape is harsh, suddenly louder, or accompanied by water on the floor, burning odor, smoke, sparking, a cracked spray arm or loose plastic. Do not reach into a running tub or restart it repeatedly to force the sound.

   Expected result: A safety symptom or visible damage is present, or the machine is cool, dry and otherwise safe to inspect externally.

   Next step: For a safety symptom, keep the dishwasher out of service and arrange qualified appliance service. Otherwise continue only with power off and the racks accessible.

   Why this matters

   Why: A scrape plus a leak, heat or electrical symptom is beyond a loading adjustment; the sound alone cannot identify a safe user repair.

2. Check 2

   Remove tall cookware, utensils and anything protruding through a rack, then check the lower and upper spray arms for free movement by hand with the dishwasher powered off. Look for a bent arm, a loose item, or a mark showing that plastic has been rubbing.

   Expected result: The arm contacts an item or rack, the arm is damaged, or it turns freely with no visible contact.

   Next step: Correct the loading interference only if the item can be repositioned safely and the arm is intact. If the arm is damaged, remains obstructed, or scraping returns with no contact, stop and schedule service.

   Why this matters

   Why: Frigidaire says dishes or utensils can interfere with spray-arm rotation and recommends checking rotation by hand. Contact explains a load-dependent sound but does not establish an internal pump fault; a damaged arm needs model-matched service or replacement guidance.

3. Check 3

   With power off, remove and clean only the accessible filter, glass trap and spray-arm openings as the exact Frigidaire manual permits. Check for glass, bone, labels or other debris without pushing anything deeper into the sump or removing pumps.

   Expected result: Debris is present in an accessible filter/trap/arm area, or those areas are clear and the scrape remains unexplained.

   Next step: Reassemble only the user-removable pieces correctly and monitor without repeated test cycles if the sound was severe. If the scraping remains, arrange service and provide the phase/timing and any debris found.

   Why this matters

   Why: Frigidaire says dish debris can become trapped in the filter, glass trap and spray arms. Clearing accessible debris may restore the intended water path, but a clear user area does not identify a circulation or drain-pump failure.

4. Check 4

   Record when the sound occurs—fill, wash/spray, drain or drying—and whether it occurs with the racks empty, while observing from outside the closed appliance only if there are no safety symptoms. Do not run an empty cycle solely to provoke a harsh scrape.

   Expected result: The sound tracks a normal phase such as water fill, alternating spray or drain, changes with loading, or persists regardless of load.

   Next step: For a phase sound that matches the official guide and has no damage or performance issue, monitor. For persistent scraping, grinding, poor cleaning, leaks or abnormal timing, stop use and request model-matched service.

   Why this matters

   Why: Frigidaire documents normal phase sounds, but a persistent scraping sound that does not change with loading is outside those descriptions and cannot be assigned to a pump, motor or bearing from audio alone.
