GE Dishwasher Error Code C4

How to fix GE dishwasher error code C4

The GE dishwasher may display the error code C4 if it fills with water twice following a power failure. This error code indicates potential problems with the float switch or a blocked drain or sump. The float switch is responsible for detecting the water level, and it may become stuck or malfunction, leading to incorrect water level detection. Moreover, a blocked drain or sump can impede proper drainage, causing the dishwasher to overfill.

How to troubleshoot the error code C4

To resolve the error code, it is advisable to inspect the appliance and address any obstructions or failures.

Press Start and Cancel/Reset

Start by pressing the touch start button and then the cancel/reset button on the dishwasher control panel. This simple action can sometimes help to resolve minor faults.

Check the float switch

Locate the float switch cover, which looks like an upside-down cup, in the front left-hand corner of the dishwasher bottom. Gently tap the cover to remove the float. This may remove the obstruction that is causing the problem.

Inspect the tray area

Check the tray on the back of the bathtub for debris. The tray looks like an upside-down cutlery basket and is prone to clogging. Remove any foreign objects that may interfere with the normal operation of the dishwasher.

If the problem persists after following the steps above, it is time to seek professional help. Contact Superior Appliance Service, and we will immediately schedule a visit to diagnose and effectively fix the problem.
