3-1
KitchenAid Dishwasher
Severity: CriticalWhat Does This Error Mean?
Error 3-1 means your KitchenAid dishwasher's wash motor (circulation pump) has a fault — it is not running or is not reaching the correct speed. The wash motor is the heart of the dishwasher: it circulates water through the spray arms to clean the dishes. Without it, no washing happens. A foreign object jamming the pump impeller is the most common cause and can often be cleared at home.
Affected Models
- KDTM354DSS
- KDFE104HPS
- KDTE334GPS
- KDTM604KPS
- KDTE254ESS
Common Causes
- Foreign object — a bone, glass shard, or toothpick — lodged in the pump impeller and jamming the motor
- Wash motor windings have burned out after years of use
- Motor start capacitor has failed, preventing the motor from spinning up
- Wiring harness connector to the wash motor is loose or corroded
- Control board not sending the start signal to the wash motor circuit
How to Fix It
-
Cancel the cycle and turn off the dishwasher at the circuit breaker. Wait 5 minutes before restoring power.
A hard reset occasionally clears a motor fault caused by a brief voltage drop rather than a true motor failure.
-
Remove the lower dish rack and take off the lower spray arm by unscrewing the central nut counter-clockwise.
The spray arm sits directly over the filter and pump inlet — removing it gives clear access to the area below.
-
Lift out the cylindrical filter and the flat mesh filter beneath it. Set both aside for cleaning.
A heavily clogged filter can sometimes restrict flow enough to trigger a motor overload — clean both filter components under hot running water with a soft brush.
-
Shine a torch into the pump inlet opening at the base of the filter housing. Look for any foreign object — a piece of broken glass, a small bone, a toothpick, or a fruit pip.
Even a small object wedged in the impeller is enough to stall the motor and trigger 3-1.
-
If a foreign object is visible, remove it carefully with needle-nose pliers. Reassemble the filter and spray arm, restore power, and test a full wash cycle.
If the object is not accessible with pliers, do not force the motor — call a technician who can safely disassemble the pump housing.
-
If the pump inlet is clear but 3-1 returns on the next cycle, the wash motor itself has failed and requires professional replacement.
A motor that hums but does not spin indicates a failed capacitor; complete silence indicates failed windings. Both require the motor assembly to be replaced.
When to Call a Professional
If the pump inlet is clear of obstructions but 3-1 persists, the wash motor windings or its start capacitor have failed. The wash motor is located at the bottom of the tub sump and requires significant disassembly to access and replace. Contact KitchenAid service or an authorised appliance technician — this is not a DIY repair.
Frequently Asked Questions
How do I know if the problem is a blockage or a failed motor?
If the dishwasher is completely silent during the wash phase (no humming or water movement noise), a blockage is likely — a jammed impeller stops the motor entirely. If the motor hums quietly but water does not spray through the arms, the impeller is spinning but not moving water, which points to a pump seal failure. If there is no sound at all even after clearing the filter, the motor windings have failed.
Is the wash motor the same as the drain pump?
No — they are two separate components. The wash motor (circulation pump) circulates water through the spray arms during the wash phase. The drain pump removes water from the tub at the end of each phase. Error 3-1 is specific to the wash motor; drain pump faults are reported as error 7-1.
Can I replace the wash motor myself?
Replacing the KitchenAid dishwasher wash motor requires removing the machine from under the counter, flipping it, and disassembling the sump and pump housing. This is not a beginner repair — incorrect reassembly can cause leaks. Unless you have appliance repair experience, it is safer and often more cost-effective to have a technician handle it.
