Maytag Washer Error Code Sr

Sr stands for stuck relay on a Maytag washer. It means a relay on the machine controller board has failed in the closed position and can no longer be opened to cut power to the motor controller. This is a control board fault that requires diagnosis and likely replacement of the machine controller board.

No, you should not continue using the washer when the Sr code is active. A stuck relay means the machine controller cannot properly cut power to the motor controller, which is an abnormal operating condition. Continuing to run the washer risks further component damage and should be avoided until the board is inspected and replaced if necessary.

Resetting the washer by disconnecting power will temporarily clear the displayed code, but the Sr fault will return if the relay on the machine controller has genuinely failed in the closed position. Because this is a hardware failure of the relay contacts or relay circuit, a reset cannot correct the underlying problem. Proper diagnosis using the P16 resistance test is needed to confirm whether board replacement is required.

A knowledgeable DIYer can diagnose this fault by disconnecting power and measuring resistance between pins 1 and 4 of connector P16 on the machine controller. If resistance is below 10 megaohms, the relay has failed and the machine controller board needs to be replaced. Board replacement requires careful handling of wiring connectors and should only be attempted by someone comfortable working on appliance electronics with power fully disconnected.

The primary repair is replacement of the machine controller board. Parts cost for a Maytag machine controller board typically ranges from $150 to $350 depending on the model. If you hire a technician, total repair cost including labor generally falls in the range of $250 to $500. Getting a repair estimate before proceeding is advisable, as older machines may not justify the cost.
