Taco Slot - H. E. error + reel doesn't always spin

[ebb]

Welcome
yes HE is hopper error
can you spin the dial by hand
check and clean the sensor where the coins should spit out
what type of coins are you using?
Check all the connection pins to the hopper

also the delay in reels spinning may be what the machine should do if you fast play the machine
in Japan you were only allowed a certain number a spins a minute so they have a built in delay feature
pics always help
