Free portable dishwasher (menlo park)

Bought on Amazon for ~$288 two years ago: https://www.

com/gp/product/B08C6GQKQW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 It worked well until last week, where I started getting an E7 error code.
There seem to be videos on YouTube about how to fix that error code but I'm too lazy / insufficiently handy to figure it out.
Maybe you can figure it out? Pickup only.
