Customer Questions and Answers for Water Inlet Valve Assembly by Whirlpool

Hello John, First and foremost is to protect yourself from personal injury. Disconnect the unit from the power supply before removal of the main back and wear gloves. Reconnect to the power supply only long enough to perform testing and disconnect from the power supply again. This type unit has to be pulled out from the wall and the back wall removed to access the door lock motor. You will have to remove the door lock motor bracket from the unit body and move the lever to unlock the door. The door lock motor 5304528973, the temperature sensor 316490000, or the clock assembly 316557116 can be the root of the problem. The most probable cause is the door lock motor assembly. The sensor tells the clock the unit temperature and if it's been in self clean it will keep the clock from unlocking the door until the temperature has dropped below about 175°F for the customers' protection. As you can see, if the sensor is out of toleration, it can prevent the clock from unlocking the door. The last thing to consider is the clock assembly. The door lock assembly gets its' power from the clock assembly but is the last ditch effort toward repair. It is also the most costly part of the circuit. The F-90 code is a fault in the door lock circuit and, other than the harness, we have covered all of the components in the circuit. Just in case the door lock assembly clears the issue of the locked door and the clock is still flashing the fault code, try this. With the door closed and the door lock assembly disconnected from the linkage, cycle the unit into the clean cycle for at least one full minute and cancel the clean cycle. If this doesn't clear the fault code, the clock will have to be replaced also.
