E1 code while operating Insignia portable washing machine NS-TWM16WH9

[suds2525]

Insignia top loading portable washing machine (Model no. NS-TWM16WH9) , bought used 1 day ago (from a couple of guys that gave off real scam vibes...). tested spin cycle but could not test other cycles due to no connection to water/drain.

Brought home and installed. Unit can fill and drain with no issue.

When set to light cycle with any load size unit will fill and agitate for beginning of 14-15min cycle. then the unit stops moving and around 12min and only a hum can be heard. after several minutes unit errors out displaying "E1". I then turn the unit off/on and select the drain cycle which does drain. it actually spins the unit very fast so the clothes that were in the machine are fully drained, however not washed.

I took the unit apart to look for obvious problems but don't see much. I checked the belt first and don't see any fraying, the belt feels tight as well. If I lock the motor with my hand I cant move the belt so it doesn't seem to be slipping...

Any ideas or easy steps to take before admitting defeat would be super helpful!

Attached are photos of the unit, more can be taken.

Thanks all,
