Cove Dishwasher Error Code 200179

Error code 200179 is a Heating Issue Fault indicating that the dishwasher's control system has detected a problem with the heating circuit or water temperature. When this code appears alongside codes 100179 or 200198, it is a strong indicator of mineral scaling on the heating components. The recommended first step is to check for scale buildup and run a descale procedure.

Running the dishwasher with an active heating fault is not recommended because the water may not reach the temperatures needed for proper cleaning and sanitization. Continued operation with a scaling issue can also accelerate damage to heating components. It is best to address the fault before resuming regular use.

A reset may temporarily clear the error code, but it will return if the underlying problem is not resolved. If scaling is the cause, the fault will reappear until the descale procedure is completed and the deposits are removed. Resetting without addressing the root cause is not a reliable fix and may delay proper diagnosis.

Start by performing the descale procedure, particularly if error codes 100179 or 200198 are also present, as the combination points to mineral buildup on the heater. If descaling resolves the companion codes but 200179 persists, inspect the heating element and wiring connections for damage or failure. Replacing a faulty heating element or repairing a wiring issue may be necessary if the fault continues after descaling.

If the cause is scaling, the repair cost is minimal and typically involves only a descaling solution. If a heating element replacement is needed, parts and labor costs can range from around $150 to $400 depending on your location and service provider. Control board replacement, if required, tends to be the most expensive repair, generally ranging from $300 to $600 or more.
