What the E:29 error code actually means

Your Jenn-Air dishwasher detected that the electrical power coming into it was too low to run safely, so it stopped and locked up. This is not a problem with the dishwasher itself but rather with the electrical supply in your home or from the utility. Checking the outlet voltage or having an electrician inspect your electrical panel is the right first step.

Questions people ask about E:29

What does E:29 mean on a Jenn-Air dishwasher?
E:29 is an undervoltage error, indicating the dishwasher detected incoming supply voltage in the range of 170V to 195V, which is below the level needed for proper operation. The appliance stops in its current position and disables all functions until adequate voltage is restored. This code points to an external power supply problem rather than a failed part inside the dishwasher.
Is it safe to use the dishwasher while E:29 is active?
No. The dishwasher has deliberately stopped operation because the voltage is insufficient for safe and reliable function. Running appliances on undervoltage can stress motors and electronics, potentially causing premature component failure. Restore proper voltage before attempting to resume a wash cycle.
How much will it cost to fix the E:29 error on a Jenn-Air dishwasher?
If the issue is a utility voltage problem or a simple circuit overload, there may be no cost beyond an electrician's diagnostic fee, which typically ranges from $75 to $150. If a breaker replacement is needed, parts and labor generally run between $150 and $300. More extensive wiring repairs or panel work can cost significantly more depending on the scope of the problem.
Can I fix the E:29 error myself?
If the cause is a utility grid issue or an overloaded circuit, you may be able to resolve it by identifying and reducing the load on the circuit or waiting for utility voltage to stabilize. However, if the cause involves the breaker panel, wiring connections, or supply wiring, a licensed electrician should perform the inspection and repair. Always measure voltage at the outlet with a multimeter before assuming the dishwasher itself needs service.
Will resetting the dishwasher clear the E:29 error?
Resetting the dishwasher may clear the error code temporarily, but if the underlying voltage issue has not been corrected, the code will return as soon as the appliance attempts to draw power for heating or pumping. Address the power supply problem first, then reset the unit to confirm the fault does not reappear.
