Dishwasher repair

The dishwasher started tripping out the RCD on the house so I pulled apart the door to see if water had leaked in to the control PCB. It was worse.

The mounting points lugs of the PCB have broken and all 4 corner screw mounts of the button panel are snapped

Not exactly an easy fix. You can see in the photo above my previous addition of a second power button to the PCB which I had to cut the rear of it out to access the copper. I am guessing that possibly with the main control board floating around the heatsinks were touching the surrounding metal door and with the moisture of it being a dishwasher cased the RCD to trip (I hope).

Tape and plastic taken off
Should be much stronger being solid

I thought it would be too hard to repair the plastic on the control board so I decided to make a carrier out of some stainless steel sheet

First side of PCB holder done.

I forgot to take a photo of it all mounted up but it did fit. I had to drill 2.5mm holes for the self tapping screw to thread into

Working dishwasher… for now
