Bosch Dishwasher Error Code Oven Temperature

This error means the dishwasher's water temperature sensor detected incoming water that was hotter than 180°F but below 210°F during a wash cycle. The appliance flags this condition because water that hot is outside the normal operating range and can damage internal plastic components, door seals, and dishes. It is most commonly caused by a home water heater set too high or a faulty thermistor inside the dishwasher.

Continued use with water temperatures above 180°F can stress and degrade plastic components, door gaskets, and spray arms over time. While this error sits below the 210°F full-lockout threshold, it is advisable to address the root cause before running additional cycles to avoid accelerating wear or causing damage to the tub interior and dishes.

A reset may clear the error code temporarily, but the fault will return if the underlying cause is not corrected. If the incoming water temperature remains above 180°F or the thermistor is faulty, the control board will detect the same out-of-range condition on the next cycle and trigger the error again. A reset is useful for confirming whether the issue is intermittent, but it is not a permanent fix.

In many cases, yes. Start by checking your home water heater temperature and lowering it to around 120°F to 140°F if it is set higher. Measure the hot water temperature at the kitchen faucet with a thermometer to confirm actual supply conditions. If the water temperature is normal but the error persists, the internal thermistor likely needs to be tested or replaced, which may require a technician depending on your comfort level with appliance repair.

If the fix is simply adjusting the water heater thermostat, there is no parts cost involved. If the NTC thermistor requires replacement, parts typically range from roughly $20 to $60 depending on the specific model. If a technician is needed for diagnosis and repair, total service costs including labor can range from approximately $100 to $250.
