Dishwasher flat cable repair

I'm looking to repair the dishwasher flat cable for the keypad because a new keypad is over $300.

I've seen repair guides online for these cables and they use a window defogger repair kit however it seems better to cut the cable straight with a utility knife and straight edge. Then slide it into a new connector if possible but I'm having trouble finding this 20 pin single row connector. A4 AMP is the only marking on the connector.

Welcome to the forums.

Sorry... I don't know of a reliable way to repair that ribbon cable.
If I determine one track to be defective I'll hand repair it.
50/50 it holds up for any length of time.
Typically I replace the entire assy.

It rarely goes bad at the plug unless it was bent during handling.
Usually there is a spot along a track or two that cracks.

If you post the model number I may be able to find you a good price.

I believe that is an AMP 1-487545-7 connector which uses 1-487547-1 pins. (but you'd have to verify with careful measurements) The problem is AMP connectors generally require special tooling to crimp to the flat cable, and the connectors are often hard to get in small quantities because they come on large reels. But you could try Digi-key as a possible source. You can also buy a length of cable with the connector already attached. If the other end is soldered into the keyboard and you are comfortable with electronics soldering, you could go that route. Or, if there is a similar connector on the other end, Digi-key sells cable assemblies with the connector on both ends.

With most Whirlpool made units.... the keypad is the mylar ribbon cable.
That's why they sell the entire front control with buttons and display.

At one time you could buy just the mylar keypad/ribbon assy.
That made too much sense for the customer but not enough mark up for the retailer.

Even putting a connector is not easy.
That is a mylar ribbon with carbon traces.

Part number for the keypad is WD34X11603 and anything over $100 is extortion considering the age of the dishwasher.

Thank you. Much appreciated.
1-487526-9 is the correct part number for 20 pins and digikey has it in stock. I asked on their forum if a tool is required or if I can simply cut the cable with a rafter square and sharp utility knife. Then slide the cable into the new connector. I await their response.
