To fix the error you have to put the safety key in start it it and wait for it to say E7. Now press stop and incline( up) together and hold for 20 seconds. Your treadmill will start to incline up. Take out your safety key. You just restarted your treadmill and can now put the safety key back and your problem will be fixed.

Hi,
By E7 it means Speed sensor feedback missing. You have to check the speed sensor mounted near the motor pully. Remove the speed sensor and clean it well Then refix it then check the tread mill by powering ON. If then also the problem remains the same , You have to replace the speed sensor.
ok

hi,
You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will try to run without setting any value or witout safety key . You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i have added the picture of IGBT for your refference. There will be a part like this in your treadmill's motor driver board. You can see the part number on it.

Problem with the Samsung Washing Machines The machine keeps coming up with the message HEI 10x


Here is a list of errors for your machine.

I hope they help you.


SAMSUNG WASHING MACHINES, ERROR FUNCTIONS

When an error occurs, the alarm noise will sound and the error code displayed in the program window. Listed below is a series of error codes you may or may not see for your model of Samsng Washing Machine. The errors are shown as blinking in O.5 second intervals until the error status has cleared. In this case, all the driving devices are turned off until the error is cleared.

1. WATER SUPPLY ERROR - Display shows 4E.

Water Supply Error occurs when water level frequency does not show changes more than 100Hz or water is not supplied up to the preset water level after 10 Minutes or more at the time of initial water supply. The error status can be cleared by turning the POWER switch OFF and back ON.

2. WATER DRAIN ERROR - Display shows 5E.

5E is displayed if the water level frequency detected is 25 KHz or less in the initial phase of the UNB -detecting cycle. The Water Drain error can be cleared by turning POWER SW OFF and back ON.

3. OVER-FLOW ERROR - Display shows oE.

Over-Flow error occurs when the water level is too high. It can be cleared by turning POWER switch OFF. Water is drained prior to POWER switch OFF. The tub is drained for 2 minutes if a frequency of more than 25 KHz is detected.

4. UNBALANCE ERROR - Display shows UE.

Laundry load is unbalanced, manually loosen any tangled laundry.

If only one item of clothing needs washing, such as a bathrobe or jeans, the final spin result might be unsatisfactory and an UE error message will be shown in the display. Unbalance error is cleared by POWER switch OFF and back ON.

5. WATER HEATER ERROR - Display shows HE, HE1.

HE, HE1 is displayed if the water temperature rises by 7 C or more in 1 Min or by 2 C or less 20 Min after heating process has started. The error can be cleared by turning POWER switch OFF.

6. WATER PRESSURE SWITCH ERROR - Display shows 1 E.

* Generated Frequency Signal of WATER LEVEL (WIL) SIW (KHz)

Normal Level = Abnormal W/L Frequency
Low Level = 30.00 Khz
High Level = 15.00 Khz

If the same signal is detected for more than 5 seconds, it is a PRESSURE SWITCH Error. When this error occurs the drain pump will operate for 3 min. and the display will show 1 E indicating a pressure switch error.

7. ABNORMAL WATER TEMPERATURE ERROR- Display shows cE.

e.g. If the water temperature is 50 C or more, during a Delicate or Wool cycle.

At the time of initial water supply, if the water temperature is not appropriate, the display will show cE. This error can be cleared by POWER SWITCH OFF.

8. WATER LEAKAGE ERROR - Display shows 11 E.

Water Leakage error occurs when the water drains naturally, (by leakage) after the washing program starts.

9. THERMISTOR ERROR - Display shows tE

E7 problem


E7 codes deal with the optical scanner unit and or the laser unit. It could also be the lamp in the scanner unit. The E7 is the main code. There is a sub code associated with it. To view the sub code hold down the start button. Below is a list of specific codes and their meanings:
E7-02: LSU trouble
E7-10: Shading trouble (Black Correction)
E7-11: Shading trouble (White Correction)
E7-12: Shading Trouble
E7-16: Abnormal laser output
If it is a laser (LSU) issue then the LSU may need replacing.
If it is a shading error the first step is to remove the platen glass carefully (with the power off because the inverter board). There is a thin white strip on the bottom side of the platen next to the slit glass. Clean this white strip with a soft cloth and a small amout of isopropyl alcohol.
Dust on the optics can also cause shading reference errors so gently blow off the mirrors with canned air.
Perform the following key procedure to reset error:
"#" key, Interrupt key, "C" key, Interrupt key
"1" key, "4"key
Start key, "CA" key.
See if unit cycles and comes back up. If not turn off and then back on the main power.
If error reappears on site technical service may be required.
