I have a whirlpool on a GFCI outlet.
I can plug a lamp into the GFCI and it works fine.
I plug in the whirlpool to the GFCI outlet and it trips immediately.
I unplug the whirlpool, reset the GFCI, plug the lamp in and it works fine.
I plug in the whirlpool and it trips immediately.
I plugged in a GFCI outlet tester and it shows that it is working properly.
I was thinking that maybe it had something to do with the whirlpool.
So I ran an extension cord to another GFCI outlet and the whirlpool runs just fine.
I next thought it had to do with the GFCI outlet itself.
I replaced the GFCI outlet and the same problem happens again.
I unplugged a few other minor things on the circuit with no change.
I have a 20A breaker and 12 gauge wire for the circuit.
While I am not 100% certain (as I think a parking lot designer wired this house) I do not see that another GFCI is on that circuit.
Any suggestions as to why this is happening and how to troubleshoot further or fix?
