Although highly unlikely, it wouldn't hurt to check the wires where they go into the pump electronics for damage. I can see in your photo that it's a 240 VAC installation, but it's conceivable (although not too common) to have 115V pumps in a 240V spa, You should see either 115V or 220V, depending upon how your hot tub is configured and the voltage on the pump. If you're comfortable using a multi-meter, you can test the connector on the circuit board that the pump is plugged into. The solenoid clicking is a good sign, but still doesn't mean that electricity is going to the pump. That may have happened a few days ago and the electrical circuit in the pump could be burned up. Sometimes you also smell electrical burning.

Rebuild or replace.ĩ out of 10 times I encounter a dead pump, it's because the motor is seized and we get that humming. Put a screwdriver into the shaft and see if you can turn it. It may be covered with a plastic cover that you can pry off. There is a screw slotted shaft in the center. Does anyone have an idea what I can check or if there something I need to replace?ĭo you hear a "hummmmm" when you press the JETS button? If so, check the back of the pump. That said, I am unsure what to check at this point. I live in a pretty rural area so my options to get someone out to check the system are pretty limited but am hopeful I can get this going without needing to send someone out. I am fairly handy, but am not an electrician nor am I very good at interpreting wiring diagrams. This all started with a few times where the pump would stop, but if we power cycled the spa at the household breaker it would work for a day or two. When I open the Balboa control box there are two black square pieces in the center and I am pretty sure the click comes from one of them (marked in an attached pic and K2/K3 in the wiring diagram). The heater does cycle as I hear a wooshing sound from it occasionally and then see HH on the spa control panel (high heat). Everything seems to be working except the pump as I get heater, lights and control panel. The pump makes no noise at all, but the Balboa Instruments control (model 52708-02) makes a solenoid clicking sound when I press the JETS button on the spa control panel. I have a California Cooperage spa from Coleman that has stopped pumping.
