Reading through this doesn’t add up in my book and awfully confusing steps taken. The Guide you found online isn’t a reset it’s for programming for when updating software or loading software.. following this sheet wouldn’t solve the issue you presented at the top. a faulty temp sensor also wouldn’t throw a breaker. A faulty heating element would. my best guess is what someone else suggested a faulty thermal cut which is internal of the pump. Generally no way to bypass. Bench testing with no wet end sometimes won’t show an issue as there is no load on the pump. best way to have diagnosed the issue was having a multi meter attached to the low speed side of the pump and watching the voltage soon as pump stopped if voltage dropped away is a board or control issue , if pump stopped and voltage still present pump issue.. glad spa is working now though.

I followed these instruction and it has worked well since then. The temperature sensor went out and must have caused the tub to throw the breaker. I replaced the sensor and the breaker has not flipped since. This of course is when the poor thing started running for only one minute and then turning it self off for about four minutes, then start again. I checked the sensors, motor, relays, circuit board, transformer, etcetera. I finally called the local shop and was told it is definitely the heater element, so I bought one from them and replaced it...That is when I took the motor in to be checked and again followed the advice of the experts... Then I found this and tried it, wonderful.

Hello. Thank you so much for the help. I checked the motor, it seemed good, so I took it to a motor shop to double check. They said is was no good so I bought a new one and put it in, ... same problem. I then figured out how to reset the control panel / computer and it works fine now. I have since made a bench grinder / buffer out of the old motor and it works... Thanks again.

Wow what a mess! I have good luck with Digikey, their shipping is great, order as late as 9pm the night before and you have it the next day, most times before noon. They do have a standard $8 delivery fee, free over $100. If you go through a lot of batteries (ie kids with toys), thier Panasonic bulk packs are good deals, and help ease the cost of the delivery if you are just buying a few things. https://www.digikey.ca/en/products/filter/terminal-blocks-wire-to-board/371 If you can measure the pitch or pin spacing on the connector, you should be able to match it up. Looks like two separate connectors there, butted together.
