Hotpoint dishwasher leaking

I have a rather generic Hotpoint dishwasher that came with the house. It recently started leaking. I don't know much about dishwashers and my wife bakes a lot at home running a cake business so I cannot afford the downtime of fooling around with it and learning as I go. I have included a photo. Behind the yellow electrical cable there is what appears to be a motor or electric switch of some sort. You can see the deposits from the water on it. It is dripping from there. I don't think there is any water connection on it but more likely something above it is dripping down onto it. Anyone have any ideas?

 

There are seals above where the pump shaft and mechanicals below penetrate into the wet area above. Fixing anything will require pulling dishwasher out from under the cabinet to access the bottom of the unit. If you find your model number you can search an online appliance parts company. They usually have diagrams so you can see how your dishwasher is put together.

Dishwashers can be relatively inexpensive. You might consider buying a cheap one to put in place an keep your wife working while you work on the main dishwasher offline. Then when you get it repaired you can put the original one back in service and keep the cheapie as an emergency backup.

 

Replacing the seal on the pump control arm is actually a fairly easy project. Post the model number and I can leave you some more info.

 

The model number is HDA3400G00WW.
Thank you.

 

The video link below illustrates how to replace the seal. They show pulling the washer out but I've done it with the unit in place.... just takes a little patience. Put a towel under unit as water will come out of the seal location when it's removed.

Part # WD8X181 is the rubber seal and WR2X7054 is the silver push-on nut.

Thank you both so much! We always planned on getting a new dishwasher but now is not the time financially. Plus we always like to wait until Lowe's has sales. We got our washer and dryer like 70% off that way. Thanks again. This forum is the best.
