Got the E3 code, replaced the board. The new board won' even fire up. Thoughts?

Error code E3 on a Hobart LXiH sanitizer/dishwasher typically indicates a problem with the water fill system. Here are a few things you can check to troubleshoot and resolve this issue:

1. Water supply: Make sure that the water supply to the dishwasher is turned on and that there is adequate water pressure. Check for any kinks or blockages in the water supply line.
2. Water inlet valve: The water inlet valve controls the flow of water into the dishwasher. Check to see if the valve is open and that there is no debris blocking the inlet. If the valve is faulty, it will need to be replaced.
3. Water level sensor: The water level sensor is responsible for detecting the water level in the dishwasher. If the sensor is not working properly, it can cause the dishwasher to display an E3 error code. Check the sensor for any signs of damage or debris.
4. Water pump: The water pump is responsible for pumping water into the dishwasher. If the pump is not working properly, it can cause the dishwasher to display an E3 error code. Check the pump for any signs of damage or debris.
5. Control board: The control board manages all the electrical functions of the dishwasher. If the control board is faulty, it can cause the dishwasher to display an E3 error code. In this case, the control board will need to be replaced.

e3. Drive motor tach fault. This means that the tachometer is not regitering any motor movement when it should. Main reasons for samsung: motor control board fault. Tachometer fault. Motor fault. Also check wireing from motor control board to motor. But this issue is not common at all with samsung.

Technical sheet says all F1 codes to replace control

E3 means "unit-abnormal protection to avoid occurence of unit damage."

Manufactures does not recommend that a homeowner try to attempt a repair on a code like this as it indicates possible wiring or internal problems. Have you checked for an internal fuse on the circuit board? I would also check the incoming power to make sure you have the proper voltage. You can also try unplugging the unit, waiting 30 seconds and plug back in to see if the code disappears.
According to A/A brands, if this code appears, shut off device and call authorized service company. I'm just trying to get you some things you can check yourself prior to doing that.

Hope this helps.

Hi, the E3 error means that the control board is detecting current going to the motor, but the motor won't turn properly. If the error code comes up all the time as soon as you press the power on button, then it means your control board is bad and reading incorrectly. If it only happens during a cycle, then you need a new motor unfortunately.

F2-E0 - Shorted Touch Pad (Keypad) - Check the connection between the touch pad (keypad) and control board (clock) to make sure it is secure.
Select the 'cancel' function and wait 60 seconds.
If error code reappears then replace the touch pad, or touch pad and control board (clock) if all one assembly.
