What 200193 means on a Cove dishwasher

Error code 200193 on a Cove dishwasher indicates that HTR1, the primary heating element or heater circuit, has remained energized for an abnormally extended period of time. The control board monitors how long the heater stays active during a wash or dry cycle. When the heater runs beyond its expected duration without achieving the target water temperature, the system flags this fault to prevent potential overheating damage or energy waste.

The most common root cause of this error involves restricted or cold incoming water supply. If the supply line runs along an exterior wall or through an unheated space, the water entering the dishwasher may be significantly colder than expected. In these conditions, HTR1 must work much harder and longer to bring the water up to the required temperature, triggering the fault before the setpoint is reached. This is precisely why the first diagnostic step focuses on checking water supply line insulation in cold environments.

Additional causes can include a weak or failing heating element that draws insufficient current to heat water effectively, a faulty temperature sensor providing incorrect readings to the control board, or low water pressure causing inadequate water volume inside the tub. A malfunctioning control board may also incorrectly track heater runtime. Each of these scenarios results in HTR1 staying on longer than the programmed threshold, causing the 200193 fault to trigger.

Common causes of 200193

  1. 01

    Cold or uninsulated water supply line

    Wiring / connection

    When the water supply line runs along an exterior wall or through an unheated area, incoming water can be far colder than normal, forcing HTR1 to run excessively long. Check whether the supply line is exposed to cold conditions and add pipe insulation if needed.

  2. 02

    Weak or failing heating element (HTR1)

    Part replacement

    A degraded heating element may draw reduced current and produce insufficient heat output, preventing the dishwasher from reaching its target temperature within the allowed time. Testing the element for proper resistance values can confirm this issue.

  3. 03

    Faulty water temperature sensor

    Part replacement

    If the temperature sensor is providing inaccurate readings, the control board may believe the water is cooler than it actually is and keep HTR1 energized unnecessarily. Inspect and test the sensor for correct output at known temperatures.

  4. 04

    Low water pressure or insufficient fill volume

    Wiring / connection

    Inadequate water pressure can result in a lower water volume inside the tub, which takes longer to heat and can confuse the system into running HTR1 beyond its limit. Verify that supply pressure meets the unit's requirements.

  5. 05

    Control board malfunction

    Part replacement

    A faulty control board may incorrectly track or mismanage the heater runtime, triggering the 200193 fault even when HTR1 and the temperature sensor are functioning correctly. This is the least common cause and should be considered only after other components are ruled out.

Frequently asked questions about 200193

What does 200193 mean on a Cove dishwasher?
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.
How do I fix error code 200193 on my Cove dishwasher?
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.
Will resetting my Cove dishwasher clear the 200193 error?
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.
Is error code 200193 on a Cove dishwasher a safety concern?
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.
How much does it cost to repair a Cove dishwasher showing error 200193?
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.
