How to fix and adjust a pressure switch of a washing machine

this is my experiment fixing my kelvinator k62.6t washing machine pressure level.
My explanation was wrong. If you turn it in, the spring compression will be stronger making it harder for the diaphragm to push it, so more water is going to fill the barrel and water level will be higher. If you turn it counter clockwise the level will be lower.

Thank you. The method worked for me for the same type of pressure switch Metalflex HD 505. I only tightened the middle screw for higher water level and tested for continuity (as you showed) while adding more water with the door closed and mains not connected. Washing is now better with more water at full load but less efficient with partial load. My machine has no half load button and originally used only about 8 liters of water for a full load at the first stage and when I submerged a washed-and-dried towel in clear water (baby bath) a very fine white powder came out of it and up to the surface of the water. After the adjustment to about 12 liters the effect is gone. Thanks again.

Thanks for your Vid. this made me realized the water didn't have to reach the switch :p and that the pressure seal was broken. all fixed now. so air triggers the switch not water! the metal seal had rusted away. I just used electrical tape after sanding surfaces, pulled it nice an tight. i then used a rubber-band to help fasten. thanks.

Thanks for the Video.

Would you be interested in a mop and bucket. Very cheap.

So if I want to increase the water level, I need to play with the middle screw but should I turn clockwise ? is 1/4 turn enough? Thanks

I think so. My explanation was wrong. If you turn it in, the spring compression will be stronger making it harder for the diaphragm to push it, so more water is going to fill the barrel and water level will be higher. If you turn it counter clockwise the level will be lower.

thanks, at the end i did buy a new one because i cracked the switch and it wasn't sealed well.

It is not a good idea to tamper with pressure switches, unless you fancy flooding out your kitchen. Buy a new one. They don't cost much. Be aware, most problems are with the chamber on the other end of the tube, not the switch.

does it matter, let natural selection take its place. It always does by default anyways. Also, at the end of the day, pressure will always be pressure, therefore adjusting the diaphram for the pressure height, will still set the switch for the proper height. At the end of the day if there is something wrong with the switch, you will have a flood, "Natural Selection" at its best!
