If your Time Timer WASH turned off unexpectedly there are a few things you can try to resolve the issue.

1. The Time Timer WASH is activated with an infrared sensor. The Time Timer WASH is designed so if something is blocking the sensor, in close proximity, for more than 90 seconds, the Time Timer WASH will go into Sleep Mode to preserve battery power. For example, if the unit is placed closely facing a wall, or a towel is covering the timer and blocking the sensor, this will cause the timer to go into Sleep Mode
To take the Time Timer WASH out of Sleep Mode, press the top button. Upon pressing the button, the unit will resume normal operation.   
Note: If the Time Timer WASH is in Sleep Mode when batteries are removed and replaced, the unit will remain in Sleep Mode even with new batteries inserted. This may make it appear that the timer is not working, when in fact, it is simply “sleeping.” If this happens, simply press the top button to wake the unit from Sleep Mode. 

2. If your Time Timer WASH was not in Sleep Mode try changing all three batteries to fresh, new AA/1.5V batteries.  For instructions on how to change the batteries view “How to Change Batteries in the Time Timer WASH”
