Ikea Dishwasher Error Code i6

The i6 code on an Ikea dishwasher signals a water temperature sensor error that is detected during the appliance's test cycle. The sensor involved is an NTC thermistor that measures water temperature and reports it to the control board. When the sensor signal is missing, out of range, or inconsistent, the test cycle registers i6. Normal wash cycles may still operate, but the fault should be diagnosed to ensure correct water heating.

The i6 error only occurs during the test cycle and may not interrupt normal wash operation. However, a faulty temperature sensor means the machine cannot accurately monitor water temperature, which could result in poor wash or rinse performance or water being heated incorrectly. It is best to address the fault before relying on the dishwasher for regular use.

Resetting the dishwasher may clear the i6 code temporarily, but if the underlying sensor or wiring fault still exists, the code will return the next time a test cycle is run. A reset is a useful first step to rule out a one-time glitch, but it does not fix the root cause. Proper diagnosis of the temperature sensor circuit is needed to resolve the error permanently.

Some causes of the i6 error are DIY-friendly, such as reseating a loose wiring connector or inspecting the harness for visible damage. Testing the thermistor with a multimeter requires basic electrical knowledge but is manageable for experienced DIYers. Replacing the sensor itself is a straightforward repair in most cases. If the control board is the source of the fault, professional service is recommended.

If only the NTC temperature sensor needs replacement, parts typically cost in the range of $10 to $40 depending on the model. If a technician is needed, labor charges can bring the total to somewhere between $80 and $200. A wiring repair may fall on the lower end of that range, while a control board replacement would be on the higher end.
