I needed to replace the motor in my pump, it was old and also ran dry for a couple of hours which finally killed the bearings and seals. After doing quite a bit of research I thought this looked do-able for someone with moderate DIY skills.
I have bought all the parts - new motor, new seal plate and seals and gaskets. I took apart and have put back together replacing old for new. When i put the electricity back on, and restarted the pump it simply hums. I switched it off quick.
So the question is any idea what i can have done wrong?
Could i have wired it incorrectly? It still has its factory configuration of 230 volts, which is the same as the old one. I did not change this on the motor.
The old wiring had 3 wires. Green for Ground, then a Yellow wired to Line 1 and a browny/yellow (confusing) wired to Line 2. I have connected the green to the Ground screw. The new motor has Line 1 and Line 2 constructed the opposite way round but i have checked and i have wired it up with the same wires on L1 and L2 as before. (I also have read elsewhere on this forum that it does not matter which way around as long as one wire on each L1 and L2.
So before i resort to getting an electrician- anyone any suggestions?
