What do you need help with? Hp Deskjet 2645 is showing error code and it refusrs to print

The carriage that goes back and forth when printing may not be moving freely. Turn off all power and see if you can move it back and forth easily. If not, put a drop of light oil on either side of the cartridge holder and slide it back and forth. You can also clean off the carriage rod with a cloth before oiling.
If this does not clear up the error code, the main board has failed and it will not be worth repairing, unless the unit is under warranty.

Embroidery compontent wont move has computer first starts up

When the embroidery unit is not connected to the machine and you power up the machine it comes up in sewing mode? Holding the embroidery unit in your hand can you move the embroidery arm back and forth and the frame carrier back and forth? Is it very very easy to move or is there resistance? If its easy, probably a belt break. If it is very very hard, take it to a dealer at least for a learned opinion.

Good day!

Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.

When the motor and the belt is OK the problem could be on electrical wiring and switch.

If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that's why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.

In sinkerator will only "hum" and not run to grind food

On The bottom of the unit there should be a place to put an allen wrench. Unplug unit, Insert wrench and turn the wrench back and forth this moves the blades if the blades move freely then nothing is stuck. If wrench does not move freely, with flash light inspect inside of disposal (the rubber flaps are usually removable to gain better eye site) if objects (bones, utensil, etc) are noticed remove them and try the wrench again if now freed problem solved. If wrench turned freely from the beginning and motor still hums. Replace disposal.

I hope this has answered your question, please rate how helpful the answer was. Good Luck and Have a great day.
