How to Fix Error F5 — Step by Step

1

Step 1: Check the error code and reset the dishwasher

First, check the error code on your Whirlpool Dishwasher's display. If it's displaying error code F5, try resetting the dishwasher by unplugging it from the power outlet for 30 seconds. Then, plug it back in and see if the error code disappears. If the error code persists, proceed to the next step. Make sure to check the user manual for specific reset instructions for your model.

💡 Pro Tip: Resetting the dishwasher may resolve the issue if it was a temporary problem.

Step 2: Check the rotor position sensor's wiring and connections

Locate the rotor position sensor and check its wiring and connections. Make sure that all wires are securely connected to the sensor and that there are no signs of damage or wear. Use a multimeter to check the resistance of the sensor's wires. The resistance should be around 1-2 kΩ (kilohms). If the resistance is outside this range, the sensor may be faulty.

💡 Pro Tip: Use a multimeter to check the resistance of the sensor's wires, and make sure to take note of the reading.

Step 3: Check the rotor position sensor's electrical connections

Check the electrical connections to the rotor position sensor. Make sure that all connectors are securely attached and that there are no signs of damage or wear. Use a multimeter to check the voltage at the sensor's electrical connections. The voltage should be around 12-24 VDC (volts DC). If the voltage is outside this range, the sensor may be faulty.

💡 Pro Tip: Use a multimeter to check the voltage at the sensor's electrical connections, and make sure to take note of the reading.

What Does Whirlpool Dishwasher Error Code F5 Mean?

When your Whirlpool dishwasher shows the error code F5, it’s telling you that the rotor position sensor isn’t working right. This sensor watches the rotor— the part that turns the wash arm and moves the spray jets. If the sensor can’t tell the control board where the rotor is, the machine may refuse to start or will stop mid‑cycle and display the F5 code.

The F5 error matters because the rotor is the heart of the wash action. Without a correct sensor reading, the dishwasher can’t time the wash, rinse, and spin cycles properly, which can leave dishes dirty or even cause water damage if the machine tries to drain incorrectly.

Common Causes of Error F5

Worn or damaged sensor – The sensor’s internal coil can wear out over time, especially in older models like the WDT1200DW.
Loose or corroded wiring – A frayed or disconnected wire between the sensor and the control board will throw an F5.
Debris buildup – Food particles can get stuck around the rotor and block the sensor’s view of the rotor’s position.
Control board fault – A malfunctioning micro‑controller can misinterpret the sensor’s signal, even if the sensor is fine.
Power supply issue – If the sensor isn’t getting the 24 V it needs, the code will appear.
Improper installation of a replacement sensor – Using a non‑OEM part or installing it incorrectly can trigger F5 again.

How to Prevent Error F5

Clean the rotor area regularly – Remove any food debris from the spray arm and rotor housing each time you run a rinse cycle.
Inspect wiring every 6 months – Check for frayed insulation or loose connections, especially if you notice any humming or flickering lights.
Use a high‑quality replacement sensor – For Whirlpool models, Part #108‑040‑002 is the OEM rotor position sensor; avoid generic knock‑offs.
Keep the dishwasher level – An unlevel unit can cause the rotor to wobble, stressing the sensor over time.
Schedule annual maintenance – A quick check by a professional can catch early signs of sensor wear before it trips an F5.

What This Repair Typically Costs

DIY vs. Professional	Parts	Labor	Total
DIY	$25–$35 (Part #108‑040‑002)	0 hrs	$25–$35
Professional	$25–$35	$75–$125 (1–2 hrs)	$100–$160

Prices vary by region and whether you use an OEM part or a compatible aftermarket replacement.

Frequently Asked Questions

Q: Can I just ignore the F5 error and keep using the dishwasher?
A: No. An F5 means the rotor sensor is unreliable. The machine may not run, or it could run incorrectly, leading to dirty dishes or water leakage.

Q: How long does a new rotor position sensor last?
A: With proper care, an OEM sensor can last 10–12 years. In high‑usage households, you might see a replacement after 6–8 years.

Q: Will replacing the sensor fix the problem if the control board is bad?
A: If the control board is faulty, the new sensor will still trigger an F5. After replacing the sensor, run a diagnostic; if the code persists, the board may need replacement.

Q: Is the F5 code the same on all Whirlpool dishwasher models?
A: Yes, the F5 code consistently indicates a rotor position sensor issue across Whirlpool’s dishwasher lineup, from entry‑level WDT1100DW to high‑end WDT1500DW.

Q: How can I reset the dishwasher after fixing the sensor?
A: Press and hold the “Start” button for 3 seconds, then release. The display should clear the F5 code; run a short rinse cycle to confirm the sensor is working.
