Fisher & Paykel Dishwasher Making Noise: Normal Sounds vs. Faults

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

1. Check 1

   Record the exact Fisher & Paykel model and identify whether the dishwasher has one or two DishDrawer drawers and whether it is integrated or another installation. Note whether the noise starts at closing, filling, washing, draining, drying, or after the cycle ends.

   Expected result: The sound occurs only after a program, during a quiet-to-audible transition, while rinse aid or water is being handled, during the wash motor stage, during draining, or whenever the drawer or cabinet moves.

   Next step: Follow the normal-sound branch if the sound matches a documented program stage and stops as described. Follow the abnormal-sound checks if it is new, harsh, metallic, repetitive, or unrelated to a documented stage.

   Stop if: Do not open an operating drawer or continue a cycle with smoke, burning odor, a leak, exposed wiring, a damaged cord or plug, or a severe impact or grinding sound.

   Why this matters

   Why: Stage-linked fan, quiet-phase, or rinse-aid sounds may be normal on applicable DishDrawer models. A noise tied to spray-arm rotation, draining, movement, or every motor run is more likely to need a physical or service check.

2. Check 2

   Without interrupting a running cycle, listen from outside and compare the sound with the documented stage: fan after a wash or after closing, a quiet phase that later becomes audible, pulsing during rinse-aid dispensing, or water-softener operation on equipped models.

   Expected result: The sound appears only in one documented stage, is steady and non-metallic, and stops or changes when that stage ends; or it is loud, harsh, scraping, knocking, or present throughout the cycle.

   Next step: For a documented normal sound, allow the stage to finish and monitor it on one subsequent cycle. For an abnormal sound, pause or stop using the model's documented controls and continue only with the safe inspection after the drawer is no longer operating.

   Stop if: Do not put hands or tools inside a running dishwasher or force a drawer open while the appliance is operating.

   Why this matters

   Why: A predictable stage sound supports normal operation on the applicable DishDrawer guide. A new or escalating sound that does not follow the stage is not explained by the normal fan, quiet-phase, or rinse-aid examples.

3. Check 3

   After the cycle is safely paused or complete, open the drawer only as the exact model guide permits. Check that dishes do not protrude into the internal lid or spray-arm path, inspect the filter and spray arm for accessible debris, and confirm the spray arm is seated and can turn freely without forcing it.

   Expected result: A dish is contacting the spray arm or lid, the spray arm is loose or obstructed, the filter is blocked or incorrectly seated, or these accessible areas are clear.

   Next step: Reposition only the protruding item and clean or refit the user-accessible filter or spray arm exactly as the model guide shows. Run one supervised cycle only if no hazard exists; arrange service if the sound returns.

   Stop if: Do not reach through moving parts, use sharp tools to dislodge debris, remove secured assemblies, or operate with the motor assembly, filter plate, filter, wire rack, or spray arm missing where the model requires them.

   Why this matters

   Why: Contact or a loose, blocked spray arm can create rattling or repeated impact during washing; a blocked filter can contribute to drainage symptoms. A clear and correctly seated wash system with continuing motor noise points further toward an internal pump, motor, or mounting fault.

4. Check 4

   If the sound occurs during draining or is an excessive motor noise on first use or after long storage, note the water level and any A3 or other fault indication. Check from outside that the drain hose is not kinked; only if the exact guide for your model gives the long-idle motor-area instruction, follow that instruction rather than improvising.

   Expected result: The drawer has excess water, the drain hose is bent or the drain connection is blocked, a fault code is present, or an applicable guide identifies no water in the motor area after first use or long inactivity.

   Next step: Straighten an accessible kink only, record the complete code, and follow the exact model guide. If a leak, repeated drain noise, code, or excessive motor noise remains, turn off water and power as directed and call service.

   Stop if: Do not disconnect plumbing under a powered or water-connected appliance, remove a pump, pour water into a model not covered by the applicable guide, or continue with a leak or electrical hazard.

   Why this matters

   Why: A bent or blocked drain path can make the appliance work harder and leave water in the drawer. Fisher & Paykel also documents a model-specific excessive-motor-noise condition after first use or long inactivity; the same remedy cannot be generalized to every dishwasher.

5. Check 5

   After the safe external and accessible checks, classify the sound as normal and stage-limited, resolved after repositioning or cleaning, persistent motor or pump noise, or a hazard-associated noise. Record the drawer, cycle, timing, fault indicators, water level, and checks completed.

   Expected result: The noise follows a documented stage and stops normally; it disappears after an accessible correction; it persists or worsens; or it accompanies a leak, fault code, burning odor, smoke, or electrical symptom.

   Next step: Use the dishwasher only when it runs normally and safely. Otherwise leave it off, turn off water and power when the guide calls for that, and give Fisher & Paykel service the exact model, sound recording or description, cycle stage, and observations.

   Stop if: Do not dismantle the motor, pump, fan, wiring, secured installation, or control; do not perform energized testing or keep restarting a machine with a hazard.

   Why this matters

   Why: A stage-limited sound or resolved dish/filter issue is less suggestive of an internal fault. Persistent or escalating noise, especially with a code, drain problem, or leak, makes an internal pump, motor, fan, bearing, control, mounting, or installation issue more plausible but does not identify a replaceable part.
