Part One: Salvaged Parts from Samsung Washing Machine WD0704CQQ


On 1st Jan 2019, I decided to disassemble my washing machine that had failed a few weeks before. I was not able to diagnose the cause of failure and it would cost too much to pay for Samsung's tech service just to come to tell me what was wrong. As I was curious to see how many interesting or useful parts I could find in it, I chose not to simply trash the entire thing away.


Besides the dozens of screws, bolts, nuts, and washers which can be reused, I found a whole bunch of other items that have the potential to be repurposed or used as parts in a project build.


This is Part One of the list of items, which covers sensors, electrical and electronic components. Part two will continue with the list and includes mechanical parts. If you are not into electricity, you will find the list of items in Part Two more interesting.


1. Pressure Switch
This part detects the water level in the drum to control the inflow of tap water into the washing machine.


Close up inspection reveals the part number of the switch http://applianceoasis.com/shopping/dn-s14t-samsung-washer-water-pressure-switch/














2. Inductor Coil
I found this plugged into the power control board, which has been discarded into the e-waste bin.

Similar to this:

3. Water Inlet Valve

4. Noise Filter



Definitely not for making the washing machine turn more silently. :)








5. Drain Pump Assembly















6. Electronic Control Board
Lots of tack switches, a loud buzzer, a rotating dial selector, and maybe the number display could be removed for other electronic projects.






7. Ceramic Heater
This is a 2000W heater element that seems to be coated in ceramics. Have already given this away.















8. Direct Drive Motor
This is one hefty motor. Potential uses for this motor include powering a bicycle or as an electric generator.









I could get well over 40VAC from it when the motor is turned by hand if I spin it fast enough. See how bright it powers an AC LED bulb in this clip - https://www.youtube.com/watch?v=OR5Mc-1kYyQ
This is the end of Part One. See an even more interesting list of parts in Part Two, especially the mechanical parts in the latter half of the list there.
