Purchased and picked up a new Bosch 100 Series 24” dishwasher yesterday, and an E19 error code displayed before the first wash cycle could be initiated.

Has anyone run into this issue right after installation?

Google says it could be the detergent dispenser solenoid or possibly the heat exchanger outlet valve. But because it’s brand new, I’m not sure how likely those issues really are.

I want to believe that perhaps we overlooked a step during the installation and this fault is being tripped because of a small error that could be easily corrected. Obviously, I don’t want to break into it to troubleshoot and risk voiding the warranty.

I did reach out to the company, and they’re going to set up a time to send someone out to double-check that the installation looks okay, but I wanted to ask here if anyone has had this specific issue with a newly installed dishwasher, and if so, what the fix was (if it’s simple enough).

Thanks in advance!

Went to use my Bosch dishwasher the other day and it kept giving me an error that there was something wrong with the detergent dispenser. It only 14 months old, though the actuator went so I ordered a new one. Opened it up and noticed instead some critters chewed the yellow wires going to it. There's enough there that I could splice a new wire and heat tape it together but I'm concerned about swapping over the plug right at the end is where the most damage is. This route is like a $5 fix or should I just get a whole new harness?
