Whirlpool Dishwasher Error Code F5

F5 indicates a spray arm blocked condition. The dishwasher's SAB sensor has detected fewer than 10 pulses per minute from the spray arm, meaning the arm is rotating too slowly or not at all. This fault does not stop the wash cycle, but it does reduce cleaning effectiveness significantly.

No, F5 is not a safety hazard. The dishwasher will continue to operate with this fault active, so there is no risk of water damage or electrical danger directly from this code. The main consequence is reduced cleaning performance, so dishes may come out dirty or spotted until the underlying cause is corrected.

If the fix is simply removing an obstruction or reseating the spray arm, there is no parts cost involved. Replacing a faulty SAB sensor typically ranges from $20 to $60 for the part, plus labor if a technician is involved. A spray pump motor replacement is a more involved repair and parts alone can range from $50 to $150 or more, with labor costs adding to the total depending on your area.

Start by opening the dishwasher and checking that nothing in the dish racks is physically blocking the spray arm. Spin the arm by hand to confirm it moves freely, and make sure it is properly seated on its mount. If the arm is unobstructed, check the spray arm nozzles for clogs, then inspect the SAB sensor wiring. If those checks do not resolve the fault, the spray pump motor efficiency should be evaluated.

A reset may temporarily clear the displayed fault, but the F5 code will return if the underlying problem is not corrected. If the spray arm is still obstructed or the SAB sensor is still underreporting pulses, the control board will log the fault again during the next cycle. Address the root cause before relying on a reset.
