Cove Dishwasher Error Code 200193

Error code 200193 means the primary heater, designated HTR1, has been running for longer than the system allows without reaching the target water temperature. The dishwasher triggers this fault as a protective measure. Common causes include cold incoming water, a degraded heating element, or a faulty temperature sensor.

A reset may temporarily clear the error code, but if the underlying cause is not addressed, the fault will return during the next cycle. Resetting is useful as a first step to confirm whether the issue is intermittent, but persistent appearances of 200193 require proper diagnosis of the heater circuit, temperature sensor, or water supply conditions.

Repair costs depend on the root cause. If only pipe insulation is needed, the fix may cost very little, typically in the range of $10 to $30 in materials. Replacing a heating element or temperature sensor, including parts and labor, can range from $150 to $400 or more depending on your location and service provider. A control board replacement is generally the most expensive repair, often ranging from $300 to $600 or higher.

Start by checking whether your water supply line runs along an exterior wall or through a cold space, and insulate it if so. If the error persists after addressing the water supply, the heating element or temperature sensor may need to be tested and potentially replaced. A qualified appliance technician can perform resistance and voltage checks on these components to pinpoint the fault.

The dishwasher is designed to stop operation when this fault is detected, which reduces the risk of overheating or damage to internal components. The error code itself is a protective response, so the unit stopping is the intended safe behavior. You should not attempt to bypass or repeatedly override this fault without identifying and correcting the root cause.
