2)Remove the front panel.

3)Slide out the control box.

4)Remove the plastic bag covering the thermistor connector, then disconnect the thermistor connector. If replacing the wash tank thermistor, disconnect the leads from the wash tank electrode. If replacing the booster tank thermistor, disconnect the closed end connectors for the booster tank water level float switch and the booster tank backup water level float switch.

5)Remove the tape or ties securing the thermistor leads, then pull out the thermistor from the wash tank or booster tank straight towards you.

6)Clean out all old sealant from inside the thermistor hole.

7)Route the wires from the new thermistor connector through the existing black plastic sleeve.

8)Apply the recommended sealant (KE4560RTV, Part Code 60Y000-11 or 4A0683-01) to the end of the new thermistor, then insert the thermistor quickly and securely.

9)Use tape or ties to secure the thermistor leads in their correct position.

10)Reconnect the thermistor connector and the wash tank electrode leads or the booster tank water level float switch and booster tank backup water level float switch leads, then bag and tie them.

11)Replace the control box and the front panel in their correct positions.

NOTICE

Be careful not to damage the wiring when handling the control box.

I. Removal and Replacement of Control Board or Operation Board

When replacing a control board or operation board, follow the precautions below.

NOTICE

1.The control board and operation board are fragile; handle very carefully.
