Reconnecting Wires in Dirty Water Pump: Steps for Electrical Installation After Disconnection

Forehead.
I use the dirty water pump every 2 months. Everything worked until yesterday. Once plugged in, I drop the pump into the tank and it doesn't work. You only hear a hum.

I took the top cover off and the moment I lifted it, I saw that all the cables had disconnected. For sure I did it when I was lifting it up ...

I suppose two glitches.
1. The capacitor has fallen - I have already bought a new one (as a precaution).
2. The pump puffed "thick" at the last pumping, but maybe not necessarily because everything is rotating inside the pump.

I am sending photos of the installation inside. How to connect all these wires?

I suspect that the red two are the working winding and the yellow auxiliary winding. I would measure the resistance between individual wires, the one with the greater resistance would be the main one, the less auxiliary one powered by the capacitor. But these are only suspicions to be checked.

Hello .
I have a picture of a similar pump, but the colors do not match yours, my colors are yellow, black, red. The only solution is to measure the windings, as my colleague Osiniak75 suggests.

Are you able to send me a photo?

You can't measure between these three wires, it should be easier, but here you go.

Blue and brown protruding upwards are 230V.

However, the winding with the greater resistance is auxiliary and the winding with the lesser resistance.

Of course, my colleague E2rd.o is right, I did not read exactly what my colleague Osiniak75 said, the main winding has a lower resistance than the starting winding.

Thank you for the photo, colleague nikusert.
After connecting the wires (it turned out that I had deduced just such a connection earlier), the pump was still humming after connecting to the electricity. As if she wanted to move but couldn't. Previously, I cleaned the bottom of the pump (it was not tragically dirty) and when it was started, I supported its start by moving the lower grinder. The pump has operated. Again, a similar pattern of operation and it works again. I left it for a while and after a while it started by itself - I didn't have to help her with that.

Malice of inanimate objects?

You did not mention before if the rotor turns slightly, to be sure check that it starts correctly every time, that it does not hum, and that it does not heat up.

I wrote that everything is spinning, a bit general, but I was nervous about this situation.
Capacitor without reservation. I'll see these windings next time. Thank you for your help

No problem, it's worth helping.
Best regards.
