The video introduces the full repair process for a BOSCH dishwashers by cleaning the pressure chamber, including the introduction of dishwasher principles, failure analysis, failure location and repair. This video is suitable for beginners and DIY. This failure symptoms are very complicated, the main symptoms are:
• Sometime, the washing temperature is not high enough
• Sometime, the water level is lower than normal
• Sometime, the drain pump is always running
• Sometime, everything including water ingress, water level and temperature is normal at beginning and come to abnormal afterwards
• In one case, it has been running for more than 3 hours, but when open the door, it always shows 1 minutes left (A well known stuck 1 minute issue)
Although the dishwasher in the video is a British model SGV46M43GB, this video can also be used as a reference for repair of BOSCH dishwashers or dishwashers from other manufacture such as AEG, Beko, Samsung, Whirlpool, Neff, Siemens etc.
The video introduces experiment of using three kinds of spot welding machines. One is purchased online, and the other two are made by myself. The three solutions are: MCU controlled mini MOSFET spot welder(the Mini DIY spot welder), the super capacitor spot welder and the MCU controlled high-current relay spot welder
Based on my test and experiment, I found that the home-made MCU controlled high-current relay solution is the simplest and most reliable.
The video introduces a simple and reliable 18650 battery spot welding machine. The spot welding machine consists of only two main components of the ESP8266 control board and high-current relay, with WIFI interface, parameters can be adjusted through the web page. It is very suitable for DIY. I made this spot welder after trying the midi DIY MOSFET spot welder I bought and the super capacitor spot welder I made, and successfully used it to rebuild my electric bicycle battery.
The video records the rebuild process of the Trex Ride+ electric bicycle BionX battery. The new battery is built with 44 Samsung INR18650-35E 3450mAH 18650 battery with configuration of 11S4P and has more than twice the original Sony US18650V 18650 battery. A balancing board has been added to extend battery pack life. The video also shows how to reset the battery level indicator of BionX G1 controller.
This is a demostrate video for the DIY simple and reliable 18650 battery spot welding machine.
