Cove Dishwasher Error Code 200142

Error code 200142 means the dishwasher's primary heating element, HTR1, did not turn off when the control system expected it to. The appliance detected that the heater remained active past its commanded shutoff point, which triggered a protective fault. The first thing to check is the mechanical operation of door latch switch LS1, as a faulty switch is a common contributor to this error.

No, you should not continue running the dishwasher while this error is present. The fault indicates the heater may not be shutting off correctly, which creates a risk of overheating internal components. Keep the dishwasher off until the cause is diagnosed and repaired.

Repair costs depend on the failed component. Replacing the door latch switch LS1 is generally the least expensive repair, typically ranging from around $50 to $150 including parts and labor. A control board replacement is more costly, often falling in the $200 to $500 range depending on labor rates and part availability. Getting a diagnostic estimate from a certified technician before committing to a repair is recommended.

Some diagnostic steps, such as inspecting the door latch switch for visible damage or debris, are within reach for a knowledgeable DIYer. However, testing relay function on the control board and checking for wiring shorts safely requires a multimeter and some electrical knowledge. If the control board or heating element needs replacement, many homeowners prefer to have a qualified technician handle those repairs.

A reset may temporarily clear the fault code, but if the underlying cause is not corrected, the error will return as soon as the dishwasher runs another cycle. Clearing the code without repairing the defective component is not a fix and could allow the unsafe condition to persist.
