Troubleshooting My Philips steam generator iron no longer heats up If your Philips steam generator iron stopped working or heating up, there can be several reasons. Please find out here how we can help you. The power light or the LED light on the handle is blinking blue If your iron is switched on and the blue power light or the LED light on the handle is blinking but the soleplate remains cold, your steam generator iron could be in auto shut-off mode. When your iron has not been used for ten minutes, it enters auto shut-off mode. To use it again, please press the on/off button. The iron no longer switches on If this is the case, there might be an internal electric problem with your iron. We recommend that you contact Philips Consumer Care and ask for a solution.
