Treadmill wont start-up

Tunturi.com or accellfitnessna.com should have the lubricant you need. Order it online and they should be able to ship it directly to your house. I service tunturi treadmills, although I haven't come across a teflon lubricated machine, it is very important with these machines you stick with the manufacturer specified lubricants.

E1 on the t20 is a speed sensor issue. If you unplug the unit and wait a few minutes, plug it back in and turn it on. If the error clears and it doesn't return, you can use the machine normally. If it does come back, typically, check the following items. The speed sensor is a hall sensor (magnetic), meaning it reads a magnet embedded into the front drive roller. Take the motor cover off and ensure that 1 - the sensor is less than 3mm from the magnet. 2- the magnet is actually in the drive roller pulley and 3 - the drive roller is turning when machine starts.

E1 will appear when the board doesn't receive a signal within 10seconds of starting the machine. If all 3 variables above are met, you can check the sensor itself by unplugging it from the board, (trace the wire back and remove the molar clip from the board) and checking the continuity with a tester. Closed or 0 when the magnet is in front of the sensor, open or 1 when the magnet is moved away. If the sensor is good, within range of the magnet (reading the magnet with a continuity test is a good indicator of placement), the magnet is in the front roller pulley and the roller is turning when the machine turns on, you're more than likely going to be looking at a bad lower board. (circuit board by the drive motor),

Buckmanservices.com solved the E1 code issue only $30 fixed it from online told me what to do

E1 error code : Unplug unit remove motor shroud and check the distance between the speed sensor and the flywheel and ensure that the speed sensor is properly attached to the motor frame. Check also speed sensor connections.
Unplug the electrical cord from the wall outlet and from the treadmill, wait 1 minute and turn the powerswitch on again. If treadmill recovers to normal operation, you may continue to use the treadmill.
Check the motor brushes either they worn or not sitting properly

LED scanning mode for verifying display functionality 3. Press ‘ENTER’ to scan DATA LINES to verify display functionality 4. Press ‘ENTER’ to scan SACN LINES to verify display functionality 5. Press ‘ENTER’ to scan LED’s to verify display functionality 6. After pressing ‘ENTER’ the TIME window shows “test” and the keypad functionality can be tested (the value displayed changes when a button is being pressed) 7. Press ‘ENTER’ to enter IO mode (TIME display shows lift motor potentiometer value, SPEED reads speed from speed sensor and DISTANCE shows heart rate pulse) Press ‘START’ to test lower board relay (a “click” sound) and then press ‘ELEVATION UP’ for 2 seconds to increase the elevation to 8%. Press ‘ELEVATION DOWN’ to decrease the elevation to minimum percentage 0% Press ‘SPEED UP’ to increase speed value and ‘SPEED DOWN’ to decrease speed value. Press ‘ENTER’ to repeat above test or ‘SELECT’ and ‘ SPEED DOWN’ buttons simultaneously to return to the normal mode
