What Rheem says to do

These steps involve electrical testing or parts replacement. Rheem's manuals tell owners to leave that work to a qualified service technician.

1. Check for obvious water leaks (If leak is present, service for unit leakage). 2. If obvious leakage is not present, disconnect rope sensor from the board and if the code is no longer present, dry (a blow dryer is an acceptable method) or replace rope sensor. 3. If error is still present once the rope sensor has been replaced, the board will need to be replaced. 4. Press and hold the "Clear Alarm" button for 5 seconds to override the alarm for 24 hrs.
