How to Fix HEAT EXCHANGER RINSE SYMBOL Error (Step-by-Step)

Wait for the dryer to cool down completely before starting.
Locate the heat exchanger access panel, usually at the bottom left corner of the dryer.
Turn the two locking levers to unlock and open the panel.
Carefully pull the heat exchanger straight out of its compartment.
Rinse the heat exchanger thoroughly with warm running water from all sides to remove lint and debris. Do not use any hard brushes.
Allow the heat exchanger to drain and dry completely and confirm the error stays cleared during a full test cycle.
Re-insert the clean heat exchanger back into its compartment and secure the locking levers on the access panel.
Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
