Read through the entire guide. and have a look at your control panel and switches in case they are different.

I found the right size switches at digikey.com part# 2449-CR1102H4.3F160CT-ND. Part# 2449-CR1102H4.3F260CT-ND is the same size but requires 260g of force to actuate the switch instead of 160g. Note: I can't seem to change the link for the second part # so if ordering the 260g force switch change 160 to 260 on the part #.

My washing machine had 9 switches so I ordered 10 (of both switches). I installed the 160g force switches as they took about the same force to actuate as the original switches.

My circuit boards have plenty of space around the switches. Any momentary tactile switch that is roughly 6.2mm on a side with the top of the button about 4.4mm above the board with only two pins with a pin spacing of 5-5.08mm should work.
