Problem: Time Remaining. Estimated cycle time is less than 2 hours.

How to Fix 2H Error

1. This is an informational status, not an error.
2. It indicates that the estimated time remaining for the cycle is typically ‘2 Hours’ or less (depending on model logic, sometimes means ‘2 Hours +’).
3. No action is required; let the cycle finish.
4. If the timer never drops, check the heating element, as the unit may be waiting for water to reach temp.

Problem: Cool Dry. Unit is running the Cool Dry phase to reduce steam and cool dishes.

How to Fix Cd Error

1. ‘Cd’ stands for Cool Dry. The wash cycle is complete.
2. The dishwasher runs a ventilation fan periodically to reduce humidity and cool the dishes.
3. You can open the door and unload the dishes at any time; this will clear the code.
4. If left alone, the code will usually clear itself after 4 hours.

Problem: Combined Water Supply/Leak Error. Indicates water supply exceeds standard amount, oversudsing, or leveling issues.

How to Fix FE/AE(RE) Error

1. This usually indicates excess suds (similar to bE) or a slight overfill.
2. If suds are visible, pour milk or oil into the tub to disperse them.
3. Verify the dishwasher is leveled properly; if tilted forward, the sensor may trip prematurely.
4. If the error persists, treat it as a hard AE (Leak) or FE (Valve) failure.
