Question about Whirlpool Duet GHW9150P Front Load Washer
"F21" is a Long Drain error code which is usually an indication that you may have an obstruction somewhere in the drainage system. Most commonly, there is something lodged in the drain pump or inlet line running from the wash tub to the pump. There is a white screw off cap on the drain pump that you can remove to inspect the pump impeller and clean. The following link explains:
Included is a follow-on link that explains how to check the drain pump to clean. You may also have to remove the inlet hose that runs from the bottom of the wash tub to the inlet side of the drain pump. Debris and small articles of clothing such as socks or under garments can become lodged in this area as well causing the drain cycle to fail.
NOTE: A "SUD" error code can often occur in conjunction with the "F21" error code. This is due to air being detected in the drainage system, which can occur if the pump is not running, or if you have an obstruction BEFORE the pump. You need to remove the inlet hose from the pump to ensure it is also not blocked. Correct your drainage system fault, and the SUD error (if displayed) should go away.
NOTE: If these preliminary measures do not correct your problem, you may have to replace the drain pump. It does not take much to damage the pump impeller or motor. Since the error code is generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced. If the pump requires replacement, the following link explains how:
These are both very simple repairs that you can perform yourself without the assistance of a repairman.
NOTE: For an explanation of all the error codes, each one of these washers comes with a technical data sheet inside.
To access, you will need to remove the lower toe panel under the door. The access screws are located under the bottom front edge of the panel. You may have to prop the two front fett of the washer up for better access ( a 2x4 works well for this). With the screws removed, the panel should drop down, then come off. If the tech sheet isn't directly behind the panel, it will be affixed to one of the interior cabinet walls.
The tech sheet lists all error code definitions, troubleshooting data, diagnostics procedures and wiring diagrams. I mention the tech sheet because you may need it to troubleshoot this error code.
Read through the information provided and let me know if you have any further questions. I hope you find this information helpful.
