Fixed the power switch on our dishwasher for the second time. It's a Hoover HEDS 668 and the mount where the switch is located started to disintegrate so I drilled a couple of holes further down, used a couple of tie wraps and it was ok for about a year then the plastic started to disintegrate even more so the ties were no good, had to drill through the front of the face plate, add a lid off of a drinks bottle and again use ties to secure the switch through the face plate.
What I'm wondering is why is the plastic becoming brittle and disintegrating.
