Frigidaire Dishwasher Error Code E:29

E:29 means the dishwasher has detected an under-voltage or over-voltage condition on its incoming power supply. The control monitors the AC line voltage and expects it to be within approximately 98 to 120VAC. When the voltage falls outside that range, the dishwasher stops operating and displays this code to prevent damage to internal components.

No, you should not attempt to run the dishwasher while E:29 is active. The code indicates the appliance is receiving power outside its safe operating range, which can damage the control board, power module, and other electronics. Address the wiring and voltage issues before resuming use.

If the issue is simply a loose wiring connection, the repair may cost little to nothing beyond your time. If an electrician is needed to address a circuit problem, expect to pay somewhere in the range of $75 to $200 depending on your location. A power module replacement, if that component is at fault, typically runs between $100 and $250 including parts and labor.

Start by checking the house wiring connections at the junction box and at the power module harness connector inside the dishwasher for looseness or corrosion. Use a multimeter to confirm the supply voltage at the power module harness connector is within the 98 to 120VAC range. If wiring is secure and voltage is correct, the power module may need to be replaced. If voltage is low, the issue is with the home electrical circuit rather than the appliance itself.

Resetting the dishwasher by cutting power at the breaker may temporarily clear the code, but it will return if the underlying voltage issue is not corrected. The fault will keep triggering as long as the supply voltage remains outside the acceptable 98 to 120VAC window or a wiring problem persists.
