Whirlpool Washer Error Code F37

F37 means the washer has detected a total steamer failure, with one or more critical values in the steamer system reading outside of acceptable limits. As a result, the steamer is completely disabled and will not function in any wash cycle. The code will persist until the steamer is replaced and the Diagnostic Test Program is run to reset the fault.

The washer can generally still run non-steam wash cycles when displaying F37, since the fault disables only the steamer system. However, any cycle that calls for steam will not function correctly. It is advisable to address the fault promptly to avoid stressing other components or masking a wiring issue that could develop further.

A reset alone will not permanently clear F37. The error resets after running the Diagnostic Test Program, but if the steamer hardware fault is still present, the code will return as soon as a steam cycle is attempted. A lasting fix requires replacing the faulty steamer before running the diagnostic reset.

The primary repair for F37 is replacing the steamer unit, which is a part-level replacement rather than a minor adjustment. A knowledgeable DIYer comfortable with appliance disassembly can perform this repair, but it requires disconnecting power, accessing the steamer assembly, and running the Diagnostic Test Program after installation. If wiring or a control board is involved, the repair becomes more complex.

Repair costs depend on whether just the steamer unit needs replacement or if additional components like the wiring harness or control board are involved. Parts costs for a steamer assembly typically range from around $50 to $150, and professional labor can add $100 to $200 or more depending on your location and the complexity of access.
