yes, if the machine is still under warranty make the dealer come and fix the console. the only other thing it could be is a faulty electrical connection but it does not sound like it. The quality of the unit should be better!!! Hope this is helpful:) thx

It might just need a simple adjustment of the running belt that can eliminate the slipping refer to you owner's manual for the procedure. It will be close to all treadmill adjustments.
Here is a generic procedure for adjusting the belt:
If the walking belt slips when walked on. Run the treadmill @ 3 to 4 mph, walk for a few minutes, Using the allen wrench, turn both rear roller adjustment bolts clockwise, 1/4 of a turn. Then repeat adjusting procedure until walking belt is properly tightened.

The safety magnet/switch is not in the correct place. Make sure it is in the correct location.

First, check and make sure the safety magnet is in the correct place. If not, place magnet. If it is, then the safety magnet sensor, sensor cable, or the console is messing up.

It was the emergency tag that you attached to yourself when you run (in case you fall over - the belt then stops etc). i had not connected it properly
