Maytag Dryer Error Code F:50

F:50 means the machine control electronics detected no voltage at the water valve relay. This code only appears during the dryer's diagnostic test mode and relates to the steam system's water valve circuit. It typically points to a loose wiring connection at either the water valve or the control board relay. It does not appear during normal drying operation.

Because F:50 only appears during diagnostic test mode and not during normal operation, your dryer may still run drying cycles without interruption. However, the steam function will likely not operate correctly until the fault is resolved. It is best to address the wiring or component issue before relying on the steam feature.

If the fix is simply reseating a loose wire connector, there may be no parts cost at all, though a service call typically runs between $75 and $150 for labor. If the water valve needs replacement, parts and labor together generally range from $100 to $250. A machine control electronics board replacement is the most expensive scenario, often falling between $200 and $400 or more depending on the model and service rates in your area.

Start by checking that all wire connectors are fully seated at the water valve and at the relay on the machine control electronics board, as outlined in TEST #8 of the diagnostic procedure. If connections are secure, inspect the wiring harness between these two components for damage or broken wires. If the wiring is intact, test the water valve solenoid for an open circuit. If all components test correctly, the machine control board may need to be replaced.

A power reset will not permanently resolve F:50 because the underlying cause, such as a loose connector or a failed component, remains present. The code will return whenever the diagnostic test is run again. The wiring and components in the water valve circuit need to be inspected and corrected to eliminate the fault.
