How to test washing machine cuircuit boards for blown capacitors
If your washing machine starts and then stops or turns off and all the lights go out or the digital display goes blank there is a good chance you may have a fault with the circuit board. You may have a bad connection, a dry joint on one of the components, or you may have a faulty component on the board this could be a resistor, capacitor, relay switch, diode, link switch, or another faulty component.

To test washing machine circuit boards for blown capacitors you can either visually inspect the top of the capacitor for damage. it may be blown or have a domed head as you can see in the picture.
You also can test them with the correct tool which is a Transistor capacitance test meter.
I have been using these Transistor capacitance test meters for years testing components on the circuit board and have saved customers thousands of pounds over the years and they only cost around £20 for a reasonable one. I have put it link here
I’ve also put the link to the left for a cheap desoldering Iron this will save you having to buy a more expensive station, but if you feel like buying a desoldering station then i have put a link here
It is also with inspecting the circuit board for any other blown components some of these can be tested using the Transistor capacitance test meter, others you cannot be tested without having the right equipment which is very expensive but normally you would get visual signs of damage, It Is Well worth going to the effort as the cost of the new circuit board normally exceeds at least a hundred pound.
I have put some components in the photographs below which can be tested and also others that you will have trouble testing without the right equipment.
Capacitors
Link switches
Diodes
Relay switches
Resistors
Transistors

This can be tested with Transistor capacitance test meter

You need special equipment to test these but you can visually see cracks in the side if damaged

This can be tested with normal meter or Transistor capacitance test meter

These can be tested with home made test rigs see our other videos on these
