Default run speedwave 2640 without controller?

I'm assuming the controller for my pump is to blame. For the past few days the pump has been turning off and then back on after a few seconds. Early this morning it turned off but did not come back on. The unit still lights up and responds to the pressing of it's buttons but the pump does nothing. The impeller assembly spins freely there's just nothing happening.

So my questions is, can I cut the power cables and connect the pump directly to the power supply? I'm assuming the brick is converting the AC to DC and not the little speed controller but I could be wrong. I already cut the wires and found only two exiting the brick and 3 entering the pump. One of the three appears to be a ground wire.

Red and white wires from the brick. Blue, red and a green/yellow entering the pump.

I don't trust this thing for regular duty and have a mag 18 running in its place. I would however like to use it for maintenance jobs like pump new sw into my sump etc when needed.

I dont think there is a way without a controller of some sort. The wires are 24v+, negative, and pwm (speed control) signal.

The power supply is just converting AC to 24VDC.

I have one connected to an arduino giving a pwm signal for ramp up/down.

I just had my power supply replaced under warranty on one of my pumps. Showed up very fast. I think its a one year warranty.

its possible it is your power supply. Mine had the green light on and when turned up on the control pad the light would go out briefly and then back on. It also made a buzzing noise when loaded up.

If you run any kind of controller you can just order the jebao cable from reef angel and run the regular power supply and have the apex or whatever controller you have tell it to be on or off.

Personally, I think the pumps are fairly good. It's the power supplies that are crap and either die or fry the controller or pump. I managed to get a good deal on a new pump sans power supply and just bought the laptop power supply to run it. I'm hoping that proves more reliable.
