Maytag Washer Error Code F3E6

F3E6 indicates that the moisture sensor strip circuit is open, meaning the control board cannot detect a valid signal from the moisture sensor. This code only appears during service diagnostic mode and is not triggered during a normal wash cycle. It points to a break in the sensor strip, its wiring, or the connector that links it to the machine's control system.

Because F3E6 only appears in service diagnostic mode and not during normal operation, the washer may still complete wash cycles without immediately displaying this fault to the user. However, a faulty moisture sensor can affect the machine's ability to detect water levels or moisture accurately, which could impact wash performance. It is best to have the issue diagnosed and resolved before continued heavy use.

Because F3E6 only appears during service diagnostic mode, it will not display during a standard power cycle or reset. However, resetting the washer will not resolve the underlying open circuit in the moisture sensor. The fault will reappear the next time a technician runs the service diagnostic, and the root cause must be repaired to clear it permanently.

Some causes, such as a loose wiring connector, can be addressed by a knowledgeable DIYer who is comfortable working with appliance wiring. However, diagnosing an open circuit requires a multimeter and familiarity with continuity testing, and the full diagnostic procedure is outlined in TEST #5: Moisture Sensor. If the sensor strip or control board needs replacement, a qualified technician is recommended for accurate diagnosis and safe repair.

Repair costs depend on which component has failed. Replacing a moisture sensor strip typically costs in the range of $20 to $80 for the part, while a control board replacement can range from $100 to $300 or more. Adding professional labor, total repair costs generally fall between $75 and $400 depending on the root cause and your location.
