The new pool pump is the same model number of the old but the motor number is different now (by one number at the end). Meanwhile, my pool is now FULL of green algae since we've been without a pump for the last month with temps in the 80's as well as rainfall. I'm feeling overwhelmed. We have already had to return one pump we ordered because hubby got the wrong HP. Now we have the right pump but the motor seems to be wired differently. Any suggestions?

Bought the pump and motor as one unit. Pump #'s are the same at Hayward Super 2 SP3020X25AZ. Old motor # is SP-1620-Z2M. New motor # is SP-1620-Z1M. I may have misled saying 2 and 3 wires. It's actually 3 and 4 wires counting the ground wires (which I wasn't). The old pump has screws for L1, L2, and L3 or 4. The new pump has screws for L1 and L2. Both have separate green screws for the ground. The wires in our box (that were wired to the old motor) are red, blue black and of course the green ground wire. Thanks guys!

your old motor is three phase and the new one is single phase ..if you check the data plates on the motors you will see this information ..you can still use the new pump all you will need to do is replace breaker and not use one of the hot wire just wire nut it off...

I used to work in a motor shop, I could not doubt answer your questions, but without seeing the motor I can do little to help. here is one thing, on the back of the plate that is on the opposite end of the motor there should be a wiring diagram. you can use this to form the two "lines" necessary to make it run, also, are you sure that the motor is designed for pool pumps? are you sure that the voltage is the same? it will either be 115 only, 115/230 or just 230. when buying a replacement motor, it is not uncommon to have to twist a couple of wires together to make it work, but like i said without seeing it, I dont have much to go on. if you could on either here or in an e-mail forward me themodel number of the new and old motor. I should be able to fix your problem from there.

Please update your question with motor make and model number and the color of the old and new wires.
-- EDIT --
Ugh! Here's the manual, nothing useful about wire color that I could see - no wonder you guys are having trouble!

I cannot find the data on the old motor ending in Z2M. The Z1M is 120V single phase 60Hz. I would suggest you examine your circuit breaker panel and verify if you have 120 (one breaker) or 240 (double breaker) servicing this pump. If it is 120 V L1 connects to Red. L2 to the Blue/Black. And obviously green to green.

Most AC systems (house current) use three wires. Two carry the alternating current - while the other is a ground. Usually the two hot wires are white and black and the ground green.
Sometimes - the case itself is grounded. Check the assembly for a screw to attach the grounding wire to. In some cases it will have a little symbol. Two lines, with an L shaped line underneath it.

most motor are dual voltage on the back of the pekerhead cover should be a diagram how to wire for songle phase 208 or three phase 208 if it is residencial i suspect single phase 208 but always test the voltage, also the diagram could be on the motor nameplate
