Appliance Repair Questions? Ask a Technician for Answers ASAP
Welcome to JustAnswer and thank you for your question. My name is***** am an expert from Germany and have been working as an equipment technician for 19 years. I work with a language translation program and I would be very grateful for your understanding.
Sorry, I can't make a call, but another expert can do it for you if you wish. I will try to help you as best I can via chat.
I am sorry that you have faced this problem!
it may be that the key lock has been activated. I hope that we can fix this quickly so that you can save technicians costs. Please try this first: press the start button for at least 5 seconds. The key symbol should then be removed and you should be able to work normally again. If that doesn't work please try this next: press two buttons. Press the rpm and Finished keys once and hold them both together for at least 5 seconds. You must then be able to use the device again.
Please do not hesitate to continue this topic if you have any further questions. I would be very happy to help you!
With best regards,
