Frigidaire Dishwasher Error Code iD1

The iD1 code means the control board has not received a tacho signal from the wash motor for 5 seconds. The tacho signal tells the board how fast the motor is spinning, and without it, the control board deactivates the heating element as a precaution. If the signal remains absent for another 30 seconds, the dishwasher will display the more serious iD0 code. The most common cause is a wiring or connector issue between the control board and the wash motor.

It is not recommended to continue running the dishwasher while iD1 is active. The control board has already disabled the heating element as a protective response, meaning the dishwasher is not operating normally. Continued use without resolving the fault can lead to escalation to the iD0 error code, which indicates a more serious motor failure. Addressing the fault promptly helps prevent additional component damage.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call can range from $75 to $150. Replacing a wash motor typically costs between $150 and $350 in parts and labor, depending on the specific model and local labor rates. A control board replacement, if needed, can push total repair costs to between $200 and $400 or more.

Start by inspecting the wire harness and all connectors leading to the wash motor, as a loose or corroded connection is the most frequent cause. Reconnect any loose plugs, and look for damaged or pinched wires along the harness. If the wiring is intact, the wash motor or its tacho sensor may need to be tested and potentially replaced. In rare cases, the control board may be at fault if all other components test normally.

A reset may temporarily clear the iD1 display, but the code will return if the underlying fault is not repaired. The error is triggered by an active condition, specifically the absence of a tacho signal, so the control board will re-detect the problem as soon as another cycle begins. A reset is useful for confirming whether a temporary glitch caused the fault, but it is not a fix for a wiring issue or a failing motor.
