I have a problem with my Dimension 1 hot tub. Sojourner

Customer Question

I have a problem with my Dimension 1 hot tub. Sojourner model (6-7 person). It's 12 years old and usually works fine but has begun to shut off and on frequently at times when is seems it is trying to start to pump. It goes off and on for a few seconds or even one minute, then shuts off, then does it again immediately. This might go on for 30 minutes and eventually it calms down, starts pumping/heating and is fine for several hours. I put in a new thermostat two years ago ago, but now, due to the tub going off and on all the time, it is often overheating. Any ideas what to do? Is the program function off and how can I reset it? Thank you for your help.
JA: Who manufactured the hot tub?
Customer: @home Maybe? This is what it says on some literature, and also, Dimension one.
JA: Do you plan on doing the work yourself?
Customer: Depends on the severity.
JA: Anything else you want the pool technician to know before I connect you?
Customer: I don't think so. Thank you.

My name is Billy.

You have 2 options.

1 - a bad motor

2 - a bad circuit board.

Follow the pump wires to the board.

Use a meter on the 2 wires mounted on board.

If when cycling...the power goes off..= replace control board.

If the power remains steady while motor goes off replace the motor.
