Question about Pool & Spa

1 Answer

Spa is warm only. It seems that the heater pump only works when other pump runs

After the larger pumps goes through its cycle, the smaller heater pump stops running after about a minute. I can feel the heater pump running, but only when the larger pump is running at either low or high speed.

As this is a 220 volt system you need to be sure both sides of the elect line is proving proper voltages at each junction.
one might fail some where at a switch or breaker an let some functions still kinda work. like in your case.

SOURCE: High speed spa pump shuts off

The motor may have a thermal cutoff if the motor draws too much current. Do you have a sufficient large gauge circuit supplying the motore? If not the actual voltage at the motor may drop, causing it to draw more current to make up for the loss of voltage, thereby tripping the motor's protective breaker. I assume the motor will start again after serveral minutes of cooling down.

SOURCE: Pump will not work in high speed

Clean the relay contacts on the board. Cut the power, ofcourse. Also, try switching the hot wire on the low side of the pump to the high side to rule out the pump.

SOURCE: pump stops running on high speed

You have a magnetek motor and it is overheating and cycling its thermal overload. A local electric motor repair shop may be able to fix it however it will likely need to be replaced. It is to costly to repair the motor if the damage is in the windings.

Assuming at that low a horsepower it is 115V, the likely replacement motor is a catalog #BN37. We sell it for $157. You are usually better off replacing the seal when you replace the motor and most Jacuzzi pumps are either a 200 or 1000. They should be around $5.

Have you called your local Watkins dealer for a service call?
I can have you look at a couple of things before you call it in.
Once you turn the system on it will operate without the heater on to purge the system of air. Once that few minutes has gone by the heater will turn on and they system will operate normally.
At what point during this cycle does the system shut down? Does it blow the circuit breaker? Exactly HOW does it shut the pump down?

It seems to me that if the intake (suction) hose is flattened, it is not allowing enough water to the pump. The suction side must be able to allow full flow and larger is always better than smaller. I think that hose must be replaced. Check with your local pool supplier.

Motor is wire to be on full cylce rather than circulate.

The wiring is not what makes a pump full cycle or circulate. If the spa motor is always on it is either because the pump relay is stuck closed, or the heater isnt keeping temerature therefor requiring the pump to be constantly running. There are also setting on newer style computer boards which determine a pump to be either "jet" or "circulation" pumps.

Also, a spa pump will run fulltime if the water is below 50 degrees F.

Your heater should shut down rite away and the pump will keep running to pump cool water through the heater. After the cool down period then the valves will go back to normal run positions.

I'm need assistance wiring my hayward 2 speed super pump up with my pool timer. the pump is working now but it's running real hot and making alot of noise.

You may have a faulty bearing ... causing the noise. The pump is actually water cooled. Do you have 2 inch line for your 2 HP pump? Small pipe makes the pump work harder. If your lines are smaller, you may want to consider a smaller pump.

the motors will run pretty warm.

Run your pump on high for best results.

If you are using a timer ... you will need a double pole switch to turn it off if it is setup for 220 VAC (which it should be, for most econimical operation)

How long does it take to heat the tub

Make sure that the inline heater has power. It should not take very long to heat since your putting hot water into it anyway. The heater is to keep water warm.

Heater not coming on.

sounds like the heater element is out. if you turn the breaker on and once the tub cycles on it trips the breaker again. it is definitely the heater element.
