The Schwinn 418, an elliptical machine made by Nautilus, has been discontinued by the manufacturer but may still be purchased through online sellers. It has a digital control screen that provides both control and diagnostic functions. During normal operation, the control screen lets you control the speed and resistance of your workout and also allows you to program your own routines. If there is an internal problem with the machine, however, the control screen will display a numbered error message. Each error message corresponds to a particular problem. If your control screen indicates "E-1," there is a mechanical problem with a magnetic plate inside the elliptical machine. Fixing the problem once you can get your hands and tools inside the machine is straightforward, but it takes some work to first disassemble the 418.
Open the battery cover from the back of the control screen and take out the batteries.
Use the screwdriver to take out the screws on the left side of the large plastic enclosure that encased the batteries. You can now bend the enclosure so that you can reach behind it to make the repairs.
Use the crescent wrench to unfasten the nut that holds the left pedal onto the crank.
Unfasten the mechanism that keeps the pedal on the crank with the allen wrench.
Unfasten the screws that keep the plastic side panel on the wheel. Use the stubby Phillips screwdriver to get these four screws off. You will have to bend the outer plastic enclosure to reach the screws; make sure you don't break it. Remove the plastic wheel side panel.
Put the batteries back in.
Find the cord that moves the magnetic plate at the base of the wheel. Manually pull the magnetic plate back from the wheel frame. Now that the plate is unstuck, the error message should disappear.
Replace all parts in the reverse order you took them apart.
