Sole (and other Dyaco brands) Error Codes

Sole treadmills with the classic LED or LCD console (F63, F65, F80, F85, S77, TT8 and their predecessors) share one error table, printed in the owner's manual. The codes are short and, unusually for this industry, the manual says what each one means.

Before you use this table: Sole, Spirit, Xterra and Fuel are all Dyaco brands and their consoles are closely related, so the same code usually points the same way. Newer touchscreen Sole models can display different messages; when in doubt, the manual for your exact model wins.

Error code

Leading zeros, dashes and spacing do not matter: E01, E-1 and E1 find the same row.

Manufacturer-documented Meaning taken from a manufacturer manual or support page. Reported Consistent owner and technician reports; the manufacturer has not published this code. Confirm with them if it matters.

Code

What it means

Where to look first

E0Also shown as: E00Classic-console Sole treadmillsManufacturer-documented

The safety switch is open: the console cannot see the safety key, or the switch is making intermittent contact.

Likely causes

Safety key not seated on the console
Tether pulling the key sideways
Worn key magnet or console switch

Source checked 2026-09-13

Remove the key, wipe the contact area and refit it squarely
Make sure the tether cannot pull the key while you walk
If E0 comes and goes during use, the console switch is the likely fault

E1Also shown as: E01, E-1Classic-console Sole treadmillsManufacturer-documented

No motor output signal: the controller commanded the motor but did not see the belt respond.

Likely causes

Belt runs briefly then stops: friction from a dry deck or over-tight belt, or the console needs calibration
Belt never moves: motor, controller or the cable between console and controller
Speed sensor not reporting

Source checked 2026-09-13

If the belt moves and then stops with E1, run the calibration procedure from your manual and check deck lubrication
If you press Start and nothing moves before E1 appears, the manual says to contact service
Check the console-to-controller cable is fully seated at both ends (unplugged)

E2Also shown as: E02Classic-console Sole treadmillsManufacturer-documented

Over-current protection: the treadmill was overloaded and the controller shut the motor down to protect itself.

Likely causes

Walking belt misaligned or too tight
Dry deck raising motor load
Heavy load at high speed or incline

Source checked 2026-09-13

Check belt alignment and tension against the manual before anything else
Lubricate the deck if it is due
If E2 returns with the belt correctly set, stop using the machine and have the motor and controller tested

Stop: Repeated E2 means the motor is drawing more than the controller allows; keep running it and you risk the controller.
