Error Code tC

The water temperature sensor isn't reading correctly

Moderate

Address soon - your appliance may not work properly

Also displayed as: No display (silent)

What This Means

The temperature sensor (thermistor) is out of order; The thermistor connector is disconnected; The Main PBA is defective

What actually causes this:

The temperature sensor wire came loose or the sensor itself went bad

First Thing to Check

Turn off the dishwasher, wait 30 seconds, and restart — if dishes are still cold after a cycle, it needs service

Parts Involved

ThermistorMain PBA

How to Fix

  1. 1

    1. Check and reconnect the thermistor connector

  2. 2

    2. Measure voltage between both ends of the thermistor — normal range: 0.2V to 4.5V

  3. 3

    3. Measure resistance between both ends of the thermistor (disconnect first). Reference: at 25 degrees C (77 degrees F) = 49.12 kOhm, at 50 degrees C (122 degrees F) = 17.60 kOhm

  4. 4

    4. If thermistor tests normal, replace Main PBA
