Cove Dishwasher Error Code 200129

Error code 200129 means the primary heating element, HTR1, did not reach its required temperature during a cycle. The dishwasher monitors heating performance and triggers this code when the expected temperature threshold is not met within a set period. This fault causes the dishwasher to stop the cycle and requires diagnosis of the heating element, its connectors, and the supply circuit.

You should not continue running the dishwasher with this error active. A heating element that is not functioning correctly means dishes may not be properly sanitized, and in some failure scenarios the element or related wiring could pose a risk. Resolve the fault before resuming normal use.

Resetting the dishwasher may temporarily clear the code from the display, but if the underlying problem with HTR1 or its circuit has not been corrected, the error will return as soon as the dishwasher attempts to heat again. A reset alone is not a repair. The heating element and its supply circuit need to be tested and the fault addressed before the code will stay clear.

A knowledgeable DIYer can perform the initial resistance test on HTR1 by disconnecting the power cord, unplugging connectors PJ22 and PJ23, and measuring resistance with a multimeter. A reading of approximately 16 ohms at room temperature indicates the element is intact. If the element tests bad, replacing it is a moderate repair, but work involving the control board or internal wiring is typically better handled by a qualified technician.

Repair costs depend on the root cause. If only the connections at PJ22 or PJ23 need reseating, there may be no parts cost. Replacing the HTR1 heating element typically runs between $50 and $200 for the part, with labor adding $100 to $250 depending on your area. A control board replacement, if needed, is generally the most expensive scenario and can range from $200 to $500 or more including labor.
